Javascript Set Text Of Div

Use the document.createElementmethod, passing in the type of element—in this case, div. The new element is assigned a CSS style through the className property, which is a standard property for all HTMLElement objects. The new div element is then added to the web page with insertBefore. Let's create the same div element with a yellow border around it as above. Inheritance is a key feature in CSS; it relies on the ancestor-descendant relationship to operate. Inheritance is the mechanism by which properties are applied not only to a specified element, but also to its descendants.

Inheritance relies on the document tree, which is the hierarchy of XHTML elements in a page based on nesting. Descendant elements may inherit CSS property values from any ancestor element enclosing them. In general, descendant elements inherit text-related properties, but their box-related properties are not inherited.

Properties that can be inherited are color, font, letter-spacing, line-height, list-style, text-align, text-indent, text-transform, visibility, white-space and word-spacing. You can then get the element's parent through the parentNode property. Once you have a reference to both the parent and the existing element, all you need to do is create the new div element and insert it. In the example below, we'll center a div with a yellow background color, instead of a border, and no text inside. We'll also add a background color to the parent container so you can more clearly see how the child div element is centered horizontally and vertically.

CSS level 2 specification was developed by the W3C and published as a recommendation in May 1998. The color will help you more clearly see how the inner div is centered. Start a new rule set with the CSS selector .center p to style the paragraph within the div.

First, you want to define the display property as "inline-block" so the paragraph flows naturally inside the div. After capturing the div element, the children prop will return a HTMLCollection list containing the HTMLParagraphElements. The childNodes property will return a similar NodeList list of nodes.

Each p tag will still be of type HTMLParagraphElements, but the NodeList can contain additional HTML nodes that the HTMLCollection list cannot. The render function actually creates DOM nodes and appends them to a DOM tree. In this case, the rendered DOM replaces the contents of the document's body tag. As HTML grew, it came to encompass a wider variety of stylistic capabilities to meet the demands of web developers.

This evolution gave the designer more control over site appearance, at the cost of more complex HTML. Variations in web browser implementations, such as ViolaWWW and WorldWideWeb, made consistent site appearance difficult, and users had less control over how web content was displayed. The browser/editor developed by Tim Berners-Lee had style sheets that were hard-coded into the program. The style sheets could therefore not be linked to documents on the web.

This is all really nice functionality, but it works against us sometimes. This is also the reason I didn't use the getElementsByTagName method to get a list of the anchor tags. Let's say you want to create a div element with a short paragraph inside and a yellow border around it, like the examples above.

In your HTML, you'd give the div a class name like "center." You can then use the class selector .center to style it with the margin, width, border, and padding properties. Divs — short for content division elements — are HTML elements that can divide your web page into sections so you can target them with unique CSS properties. For example, say you want to include a caption below an image in a blog post. In that case, you could wrap the text in a div element and apply CSS to that specific element. Unlike other programming languages, we do not use getter and setter methods to set a text to HTML elements.

The HTML element object for a div has an attribute called the innerHTML. We can use it to get and set the content of the HTML object. That is, it reflects any change to the element property in the browser on refresh. UseCallback will return a memoized version of the callback that only changes if one of the dependencies has changed. This is useful when passing callbacks to optimized child components that rely on reference equality to prevent unnecessary renders (e.g. shouldComponentUpdate).

To create elements, you need to use the relevant document's createElementNS() method, passing in the SVG namespace and the tag name. You then will most likely want to add it to the SVG element with appendChild(). You can also use the insertBefore() or insertAfter() methods of an SVG element. As you can see, using setAttribute to change the style element property can significantly impact on previous settings, including any inline CSS settings. When you remove an element from the web document, you're not only removing the element, you're removing all child elements. You can also get a reference to the removed element if you want to process its contents before it's completely discarded.

The latter is helpful if you want to provide an undo method in case the person accidentally selects the wrong table row. You'll have to use a variety of techniques to accomplish this task. If the third paragraph doesn't exist, we can append the element to the end of the div element using the appendChild method instead. The document.createElementmethod creates any HTML element, which then can be assigned other elements or data and appended or inserted into the page. In the solution, the new paragraph element is inserted before an existing paragraph using the insertBeforemethod.

The existing Document Object Models provide a plethora of methods you can use to create new web document elements. Say you want to create a div element with a short paragraph inside and a yellow border around it. In your HTML, you'd give the div a class name like "center." You can then use the CSS selector .center to style it with the border and text-align properties.

In practice, only insertAdjacentHTML is used most of the time. Because for elements and text, we have methods append/prepend/before/after – they are shorter to write and can insert nodes/text pieces. The document.getElementById function returns an HTMLElement. HTMLElement interface extends the Element interface which extends the Node interface.

This prototypal extension allows for all HTMLElements to utilize a subset of standard methods. In the code snippet, we use a property defined on the Node interface to append the new p element to the website. Throughout this tutorial, we touched on React concepts including elements, components, props, and state. For a more detailed explanation of each of these topics, check out the rest of the documentation. To learn more about defining components, check out the React.Component API reference.

We learned earlier that React elements are first-class JavaScript objects; we can pass them around in our applications. To render multiple items in React, we can use an array of React elements. In React, function components are a simpler way to write components that only contain a render method and don't have their own state.

Instead of defining a class which extends React.Component, we can write a function that takes props as input and returns what should be rendered. Function components are less tedious to write than classes, and many components can be expressed this way. Here, ShoppingList is a React component class, or React component type. A component takes in parameters, called props (short for "properties"), and returns a hierarchy of views to display via the render method. If you use this optimization, make sure the array includes all values from the component scope that change over time and that are used by the effect. Otherwise, your code will reference stale values from previous renders.

Learn more about how to deal with functions and what to do when the array values change too often. The clean-up function runs before the component is removed from the UI to prevent memory leaks. Additionally, if a component renders multiple times , the previous effect is cleaned up before executing the next effect.

In our example, this means a new subscription is created on every update. To avoid firing an effect on every update, refer to the next section. In addition to these testing tools, many sites maintain lists of browser support for specific CSS properties, including CanIUse and the MDN Web Docs.

CSS that is not supported by older browsers can also sometimes be patched in using JavaScript polyfills, which are pieces of JavaScript code designed to make browsers behave consistently. Each web browser uses a layout engine to render web pages, and support for CSS functionality is not consistent between them. Because browsers do not parse CSS perfectly, multiple coding techniques have been developed to target specific browsers with workarounds .

Adoption of new functionality in CSS can be hindered by lack of support in major browsers. For example, Internet Explorer was slow to add support for many CSS 3 features, which slowed adoption of those features and damaged the browser's reputation among developers. Tools such as BrowserStack have been built to reduce the complexity of maintaining these environments. Prefixed properties are rendered obsolete by the time of standardization.

Programs are available to automatically add prefixes for older browsers, and to point out standardized versions of prefixed parameters. Since prefixes are limited to a small subset of browsers, removing the prefix allows other browsers to see the functionality. An exception is certain obsolete -webkit- prefixed properties, which are so common and persistent on the web that other families of browsers have decided to support them for compatibility. Next, I'm using the setAttribute method to change the element's height. A couple of things happen when I used the setAttribute method in the example. The element is now 200 pixels wide, 100 pixels tall, with a green background, and the font reverts back to the default font for the browser , and the default font color, black.

Next, the font-family for the element is set to Courier, using the array notation, which is another approach you can use to set and get style property values. Now the div element is 500 pixels wide, with a yellow background, and its font family is Courier. Luckily, as the solution demonstrates, we have other methods that do what we want, without the interesting side effects. The cloneNode method is used to clone the child elements, which the solution places just before the link.

Once the children are taken care of, the entire link element is moved to the bulleted list using appendChild on a newly created list element , which is then appended to our unordered list . The childNodes collection would have a length of 2 for the text node and the em. In Example 12-1, the solution for this recipe is embedded into a web page that originally consists only of one named divelement. When this element receives a click event, a new sister div element is created and inserted into the document before the existing element.

Both the innerText and innerHTML properties let you access and change the contents of a tag. InnerText returns the text without any descendants or spacing. InnerHTML returns the text including any descendants and spacing. To horizontally and vertically center a div within a div whose height and width is unknown, you can use the transform property instead of the margin property. You'll still use the CSS position, top, and left properties.

To truly center the div horizontally and vertically, you need to define the transform property. Specifically, you want to move the div 50% to the left and up from its current position. That will tell the browser to put the center of the div in the center of the page.

In most cases, you can center text vertically in a div using the padding property. While you can use the longhand form, using the shorthand padding property is easier because you only have to set two values. Since you want to center the text vertically, the first value can be any positive length or percentage value. Using CSS, you can center text in a div in multiple ways. The most common way is to use the text-align property to center text horizontally. Another way is to use the line-height and vertical-align properties.

The last way exclusively applies to flex items and requires the justify-content and align-items properties. Using this method, you can center text horizontally, vertically, or both. Tag any time the overall document direction is right-to-left . This sets the default base direction for the whole document.

All block elements in the document will inherit this setting unless the direction is explicitly overridden. But do use logical ('end' and 'start') on properties or values related to margins, padding, alignment, etc. to make it easy to manage direction changes during localisation. However, using the innerHTML causes the web browsers to reparse and recreate all DOM nodes inside the div element.

Therefore, it is less efficient than creating a new element and appending to the div. In other words, creating a new element and appending it to the DOM tree provides better performance than the innerHTML. The best part about the lib.dom.d.ts type definitions is that they are reflective of the types annotated in the Mozilla Developer Network documentation site. For example, the HTMLElement interface is documented by this HTMLElement page on MDN. These pages list all available properties, methods, and sometimes even examples. Another great aspect of the pages is that they provide links to the corresponding standard documents.

Apple Watch Series 6 Vs 7 Reddit

Its apps are basic, although it has seen an upgrade from monochrome to colour touchscreen. Last year, the Series 6 was the most full-featured watch that Apple offered. It had the most complications and the most onboard health-tracking sensors, like optical wrist-based SpO2 measurements and ECGs, all of which I like and found useful. It also has faster charging times than earlier models, which is a necessity if you want to wear it overnight to track your sleep and charge it in an hour while you shower and eat breakfast before work. The Apple Watch Series 7 doesn't have an official release date yet, and by all indications, it's pretty similar to last year's model.

The most significant difference is the Apple Watch Series 7 has a bigger screen and thinner bezels, making the Apple Watch Series 6 screen look smaller side-by-side. Not to mention that the Series 7 comes in two slightly bigger case sizes — 41mm and 45mm — making the device just a bit bigger than the Series 6. The Garmin Forerunner 55 and 245 Music are two less-expensive options worth a look for moderate runners. Those who love the 745's approach but don't need things like music storage, blood oxygen monitoring, or running-cadence analysis can save a significant amount with a Forerunner 45.

The Forerunner 245 Music, meanwhile, may be better for those who don't need an altimeter or tracking for hikes and other outdoorsy activities but want to retain the lion's share of 745's activity-tracking features. The Apple Watch Series 7 builds on the SE's feature set, with a larger display that curves around the edges (that's always-on), along with blood oxygen monitoring, faster charging and exclusive watch faces. While the 3 and SE have aluminium cases, the 7 has options in stainless steel and titanium, too, with more colour and band options. The Apple Watch Series 7 is considered one of the best smartwatches on the market with a robust App Store that even includes games.

The Apple Watch is known to be among the best health trackers, with ECG, heart rate, blood oxygen sensors, and the abilityto detect falls as well as send an SOS in the event of a car accident. As a fitness tracker, the Apple Watch reports activity completion in rings that make it easy to understand where the wearer is for the day with just a glance. It's the do-everything and go-everywhere smartwatch that quickly becomes an important part of the wearer's daily routine. The Apple Watch Series 7is still the best all-around smartwatch available. No other wearable offers close to the app variety, ecosystem cohesiveness, and third-party support that the Apple Watch does.

Battery life is just okay at roughly one day per charge, but charging from zero to 100 now takes just over an hour. The new, bigger screen offers larger font sizes and more space to read fitness data and notifications, too. Fitness tracking could still use more context, but the Series 7's all-around package is tough to beat. Meanwhile, the Apple Watch SE can save you a few bucks depending on your needs. But the smartwatch still has an impressive array of health monitoring features to track ECG, blood oxygen levels, heart rate, and plenty of other metrics.

It offers true "leave-your-phone-at-home" usefulness, with wide first- and third-party app support and LTE connectivity. The Apple Watch Series 7 is a minimal upgrade on the inside, but the new larger display with thinner bezels looks gorgeous. While it has the same battery life as last year's model, the Series 7 has a USB-C charging cable included in the box that charges the watch up to 33% faster, so you'll spend less time juicing up than before.

The Sense also offers cutting-edge fitness-tracking hardware, like an ECG monitor and blood oxygen readings, although the latter doesn't offer spot readings unless you pay for Fitbit Premium. Requisites like GPS, heart rate monitoring, and an altimeter are all on the Sense, as are skin temperature monitors and electrodermal activity sensors for stress measurement. Note that the altimeter can be inaccurate in some weather conditions. The Apple Watch Series 7, announced in September 2021, is the current iteration of the Apple Watch that originally launched in 2015 and replaced the Series 6. The Apple Watch Series 7 builds on the design of previous Apple Watch models with a more rounded design and offers some notable new features including larger displays, improved durability, and faster charging.

There are some tradeoffs with the Apple Watch Series 3 because it is a much older model, such as a smaller display, an older chipset, and the lack of a compass, fall detection, ECG, and blood oxygen monitoring. If at any point this past weekend you missed out on an Apple Watch deal you were keeping tabs on, fret not, you can still pick up the 40mm, GPS version of the Apple Watch Series 6 for just $299 at Best Buy. That's a $100 discount on the otherwise $399 wearable, which offers built-in sleep tracking, a blood oxygen sensor, and an always-on display. It's a more affordable alternative to Apple's new Series 7, with features you won't find in the similarly priced Apple Watch SE. The Series 7's facelift is hard to see if you don't have it side-by-side with a Series 6, and if you already own the latter, the newest model isn't worth the upgrade. New charging coils, paired with a USB-C Apple Watch charger, have cut zero-to-100 charging times in half, from 2.5 hours to 1.25 hours.

That said, overall battery life remains at 18 hours, or roughly a day's worth of use. Samsung's Galaxy Watch 4is the best all-around wearable for Android users, especially Samsung phone owners. Its classic watch styling looks good, and its rotating bezel controls are intuitive. Some of its more advanced health-tracking features require a Galaxy phone, but it's still a very capable fitness tracker on the whole. Its collaboratively created software from Google and Samsung means it keeps the polish Galaxy watches were known for while adding a growing list of popular apps to support it. The Apple Watch may not be as powerful as an iPhone or iPad, but it offers a lot of versatility for such a small package.

Depending on which Apple Watch model you own, there are a variety of settings to tweak and activities to perform, from listening to music and tracking your workouts to monitoring your heart rate and viewing your photos. The Apple Watch Series 7 offers the same health monitoring features available with the Series 6. A built-in accelerometer and gyroscope enable other important health-related features such as fall detection. The bigger screen does look great and gives the Series 7 the ability to have a full QWERTY keyboard on your wrist. Yet, there aren't any new sensors or standout features to really wow us.

A faster charge is a welcome addition, even though the battery life is still only about 18 hours. Apple usually refrains from revealing the processor and RAM options on its wearables. However, Apple was categorical in stating that it has primarily focused on energy usage from the bigger and brighter screen. The efficiency doesn't relate to battery life enhancement here, so on paper it's still 18 hours of playback time; though now the watch supports 33-percent faster charging USB-C. (To that end, a brighter screen and faster charging are better, too.) The Apple Watch Series 7 is absolutely the best Apple Watch to date.

There's no question that people coming to the device for the first time should pick one of the Series 7 models. It lacks the same sensors just mentioned in the SE's omissions, it's a good ways slower than either the SE or Series 7, and it further loses the always-on altimeter, though intermittent altimeter readings are available. But it's still an attractive buy for the basics at its MSRP of $200, and it's often on sale for less than that. Just be aware that users have experienced issues updating their Series 3s with the watch's limited 8GB storage.

It's also better viewed as a smartwatch than a health or fitness tracker given all the features it lacks compared to the Series 7, Series 6, and most of their competitors. Fitness-wise, the Series 7 has its bases covered with over 50 different activity-tracking modes and an easy way to see your health vitals from exercises, sleep, and everyday life via Apple's Health app. The app focuses mostly on trends, so it's not the most insightful, and it doesn't offer the most guidance of any watch in this guide. But consistency is key to any health regimen, and guidance via Apple Fitness+, Apple's paid fitness subscription (priced at $10 a month or $80 a year), helps to provide a bit of that missing guidance.

Five ATM water resistance and IPX6 dust resistance—the latter of which is new to the Series 7—along with sturdier screen geometry make this the most durable Apple Watch yet. While the Apple Watch Series 3 is an older version , it is still a great smartwatch with fitness and health features at a low price point. Its display is much smaller and not as bright as the other two Apple Watch versions, with a lower resolution. It gives high and low heart-rate notifications and can check on irregular heart rhythms.

It has built-in GPS, optical heart sensor, gyroscope, altimeter, speaker and microphone . The Apple Watch Series 7 has a bigger, brighter, and tougher display that extends all the way to the edge of the device. There isn't any flashy new gimmick or headlining health feature in this model, but there are still a handful of changes worth exploring. New colors, faster charging, and exclusive edge-to-edge watch faces add up to an iterative, yet desirable upgrade. As an ultra low-cost option, Apple is continuing to sell the Apple Watch Series 3, priced starting at $199. The Series 3 has an older design with a smaller display, a much slower S3 chip, and no blood oxygen sensor or ECG function.

It is GPS only and lacks a few other bells and whistles like always-on altimeter and compass that are found in the other Apple Watch models. The Series 3 is several years old at this point and is using outdated technology, so we do not recommend purchasing it. Apple bases "all-day" battery life estimates on 90 time checks, 90 notifications, 45 minutes of app use, and a 60-minute workout with music playback via Bluetooth. For LTE models, Apple assumes four hours of LTE connection and 14 hours of connection to an iPhone.

In some situations, the Apple Watch will drain faster, such as during calls or workouts. Anyone who tells you they can't tell the difference are crazy lol. I love the keyboard, faster charging and the bigger screen for me was a no brainer. If by some chance you get a scratch, you can take it to a jeweler and they will buff it out for you. I've decided to upgrade my old Fitbit and buy my first apple watch.

Are there any significant features that make it worth going with this model? If not, I would probably prefer series 6 since its price has been reduced. The Apple Watch Series 6 is still a reliable and excellent Apple Watch. With all the features you love, like an always-on display, blood oxygen sensor, ECG app, and more, it isn't missing any major features compared to the Series 7.

Although it doesn't have a new larger display and still uses the same old case size — 40mm and 41mm — you can actually order the Apple Watch Series 6 right now and maybe even find some great deals. With at least three worthwhile Apple Watch options at descending price points, it's hard to create a ton of separation among the runners-up. The Fitbit Sense's main draw, though, is having almost all the fitness and health sensors of the Apple Watch Series 6 but with universal compatibility for use with Android, iPhone, and even computers. It also has between two and three times longer battery life than the Apple Watch, which translates to almost a full week of use.

As mentioned, the Series 7 is essentially just a faster-charging and face-lifted Series 6 that starts at $400. While stock lasts, you can often find the Series 6 for around $50 less than an equivalent Series 7 model. Alternatively, if you're not in need of the always-on display, blood oxygen sensor, and ECG sensor, then you can save a nice chunk of change with the otherwise similarApple Watch SE, which retails for $279. TheVivomove Luxe, Style, and 3/3S share elegant looks and premium materials at varying price points, making them nice pieces of jewelry that don't compromise too much on moderate fitness tracking.

The Garmin Lily, meanwhile, is an especiallygreat choice for women or those with smaller wrists. It requires a phone for GPS, but it delivers useful stats for all sorts of activities and notifications with a fashionable aesthetic. Aside from the Sense and Versa family, Fitbits don't run multiple apps like a smartwatch, but they are directly comparable on many of their fitness-measuring functions, design themes and functions. And most feature on-wrist notifications such as Caller ID, Texts and WhatsApp - which, to be fair, are the most used non-fitness apps on most smartwatches anyway.

Apple is known for its smartwatches, and Fitbit for itsactivity trackers and fitness and health smartwatches. But the boundaries and functions are getting blurred with Fitbit adding apps and lovely touchscreens to its trackers, and Apple adding more health features to its Watch. Fitness aspects are unchanged with the same workout-tracking, heart rate detection, and awards as previous models.

Users can take an ECG, notify emergency contacts in the event of a fall, and get abnormal heart rate notifications as well. To take a reading, open the Blood Oxygen app on your watch and tap the Start button to begin the scan. If the measurement is successful, the screen will then indicate the percentage of your blood oxygen level. For best results, make sure your watch is not too low on your wrist and that the band is snug but comfortable. Keep your hand and wrist as still as possible during the reading. The most significant update to the new smartwatch, arriving on Friday, is a slightly larger touch screen, which can fit more text from messages and features bigger, easier-to-press buttons.

However, if you don't own Apple's signature smart watch at all, there are a few reasons to opt for this latest model. The bigger screen is obvious, but the Series 7 also includes extra durability features such as crack, dust, and water resistance. Not only is the Series 7 the fastest model, it should also be the strongest.

One can continuously debate about the squared-off design of the Apple Watch and the round dial of the Samsung Galaxy Watch. Truth be told, the design is only momentary, the difference lies in the fitness tracking ability, the set of features, selection of third-party apps, and the option for mobile payment. Garmin's Forerunner 745 is our top runner's watch for its deep training stats, useful yet easy-to-read analysis for all athletes, and suite of dedicated runner's tools. It lacks a touchscreen, but with GPS, 24/7 heart rate, all-day blood oxygen monitoring, and music storage for up to 500 songs, it's a capable companion for running, swimming, biking, and most other sports. Building on everything on the Versa 3, the Fitbit Sense adds a bunch of sensors that are built around health as well as fitness. It has stress-management tools based on sensors that measure Electrodermal Activity and Skin Temperature.

There's SP02 monitoring for blood oxygen and electrocardiogram to check your heart's rhythm with high and low heart-rate notifications. The Apple Watch Series 8 could perhaps offer new health features like blood pressure monitoring, temperature tracking for fertility, sleep apnea detection and more. It may also have the new flat-edged design that was initially rumored for the Series 7. All Hermès models feature a silver or space black stainless steel Apple Watch body paired with one of the Hermès signature hand-crafted leather bands and an additional orange Hermès-branded Apple Watch Sport band. Hermès Apple Watches include unique watch faces based on Hermès watch designs.

With the Series 7, there are color updates across the Classic, Attelage, and Jumping styles, as well as two brand new Circuit H and Gourmette Double Tour styles. The Apple Watch can now charge 33 percent faster charging compared with Apple Watch Series 6 thanks to a new charging architecture and Apple's Magnetic Fast Charger USB-C Cable and an 18W or higher power adapter. This means that just eight minutes of charging time can provide up to eight hours of sleep tracking. The Magnetic Fast Charger USB-C Cable ships with the Apple Watch Series 7, but users will need to supply a 20W or higher power adapter to get fast charging. The new models feature a larger, re-engineered Retina display with more screen area due to slimmer borders. The display has a unique refractive edge that almost curves to the casing.

There are interface improvements and two unique watch faces to take advantage of the larger displays. The Series 7 continues to feature the low power OLED Always-On display technology introduced with the Series 5, allowing users to see their watch face and complications at all times. The Apple Watch Series 7 is Apple's latest smartwatch, featuring a larger always-on Retina display, a more rounded design with a larger casing, improved durability, and faster charging, starting at a price of $399.

Apple Watch Series 6 Vs 7 Sure a slightly bigger screen is a nice upgrade and the slightly faster charging is also nice but those are not huge changes. Apple Watch Series 7 was expected to feature a new design, enhanced health features and more. Ultimately though, the watch is not a huge upgrade from the last year's Apple Watch 6. The notable change is a thinner bezel, which despite almost the same body size provides a bigger, brighter display and tougher crystal.

There also aren't any new health tracking features – it looks like we'll have to wait for next year's Apple Watch 8 for the rumored blood pressure and glucometer sensors. And while the Apple Watch 7 reportedly has a new chipset, it seems this isn't really an upgrade on the one in the Apple Watch 6. The standard silver, black or gold colors are only available across the stainless steel and titanium models.
