We can divide this question into 2 parts

• Set the value of Label control using jQuery
• Get the value of Label Control using jQuery

Before answering each of these questions, we can revisit some basics for better understanding

asp:Label is a server side ASP.Net control and resides at server side. When you request a page which contains Label control, ASP.Net converts it to span html element while sending to the cient(browser).

jQuery is a javascript library which works at client side.

And jQuery does not have any knowledge about ASP.Net or any server side technology, let alone server side control.javascript

jQuery is a powerful and widely used JavaScript library to simplify common web scripting task.

jQuery is a fast, lightweight, and feature-rich JavaScript library that is based on the principle "write less, do more". It's easy-to-use APIs makes the things like HTML document traversal and manipulation, event handling, adding animation effects to a web page much simpler that works seamlessly across all the major browsers like Chrome, Firefox, Safari, Internet Explorer, etc.

jQuery also gives you the ability to create an Ajax based application in a quick and simple way. Big companies like Google, Microsoft and IBM are using the jQuery for their applications. So you can easily understand how popular and powerful the jQuery is?

jQuery was originally created by John Resig in early 2006. The jQuery project is currently run and maintained by a distributed group of developers as an open-source project.

You can save a lot of time and effort with jQuery. So bookmark this website and continue on.microsoft javascript

WAI-ARIA, the Web Accessibity Initiative - Accessible Rich Internet Applications Suite, defines a way to make Web content and Web applications more accessible to people with disabilities. It especially helps with dynamic content and advanced user interface controls developed with Ajax, HTML, JavaScript, and related technologies. Currently certain functionality used in Web sites is not available to some users with disabilities, especially people who rely on screen readers and people who cannot use a mouse. WAI-ARIA addresses these accessibility challenges, for example, by defining new ways for functionality to be provided to assistive technology. With WAI-ARIA, developers can make advanced Web applications accessible and usable to people with disabilities.javascript

Package, dependency and environment management for any language---Python, R, Ruby, Lua, Scala, Java, JavaScript, C/ C , FORTRAN

Conda is an open-source package management system and environment management system that runs on Windows, macOS, and Linux. Conda quickly installs, runs, and updates packages and their dependencies. Conda easily creates, saves, loads, and switches between environments on your local computer. It was created for Python programs but it can package and distribute software for any language.

Conda as a package manager helps you find and install packages. If you need a package that requires a different version of Python, you do not need to switch to a different environment manager because conda is also an environment manager. With just a few commands, you can set up a totally separate environment to run that different version of Python, while continuing to run your usual version of Python in your normal environment.ruby javascript

Today, you can't do anything in JavaScript without bumping into a CLI.

Want to install a library? yarn add it. Want a React app? create-react-app. Want to format your JavaScript? prettier --write. Want your types checked? tsc. Bundling? Pick from webpack, rollup, or parcel. Deploying? now or netlify deploy.

CLI's are everywhere, and even if you don't write them, sooner or later you'll have to debug them.

This workshop serves as a comprehensive survey of the state of the art of CLI tooling for everyone looking to make an impact in open source, across their company, and even in their own productivity.react javascript typescript

We are in a time where it’s necessary to develop in both mobile and web for your software. However, maintaining three different codebases for iOS, Android, and Web development results in immense time strain when in most cases you are developing the exact same solution. This has lead to the rise in cross-platform development tools that have traditionally used Javascript to develop apps that utilize Web Views to give native-esque experience. However, a relatively new player which came out of beta earlier this year is Google’s Flutter Framework.javascript flutter

Recently Google released the technical preview of Flutter Web, an extension to Flutter for the modern web. So what does this mean? It means that now it’s possible to have one single code base for Android, iOS and the Web. Since Flutter is built using Dart, which includes production-quality compilers for both native machine code and JavaScript, web support was just a matter of time.javascript unity flutter dart

Effective Dart

Over the past several years, we’ve written a ton of Dart code and learned a lot about what works well and what doesn’t. We’re sharing this with you so you can write consistent, robust, fast code too. There are two overarching themes:

Be consistent. When it comes to things like formatting, and casing, arguments about which is better are subjective and impossible to resolve. What we do know is that being consistent is objectively helpful.

If two pieces of code look different it should be because they are different in some meaningful way. When a bit of code stands out and catches your eye, it should do so for a useful reason.

Be brief. Dart was designed to be familiar, so it inherits many of the same statements and expressions as C, Java, JavaScript and other languages. But we created Dart because there is a lot of room to improve on what those languages offer. We added a bunch of features, from string interpolation to initializing formals, to help you express your intent more simply and easily.

If there are multiple ways to say something, you should generally pick the most concise one. This is not to say you should code golf yourself into cramming a whole program into a single line. The goal is code that is economical, not dense.javascript dart

Building interactive sites can involve sending JavaScript to your users. Often, too much of it. Have you been on a mobile page that looked like it had loaded only to tap on a link or tried to scroll and nothing happens?

Byte-for-byte, JavaScript is still the most expensive resource we send to mobile phones, because it can delay interactivity in large ways.javascript

When you first encounter Regular Expressions, they may seem like a random string of gibberish. While they might look awkward (with a somewhat confusing syntax), they are also extremely useful.

The truth is properly understanding regular expressions will make you a much more effective programmer. In order to fully understand the regex world you first need to learn the basics concepts, on which you can later build.

So without further ado, lets get started :)perl javascript

About two years ago, I begrudgingly opened Visual Studio Code (VS Code) for the first time. The only reason I even did so is that I was working on a TypeScript project (also quite begrudgingly) and I was tired of fighting with the editor and the compiler and all of the settings that I needed to make a TypeScript project work. Someone mentioned to me that TypeScript “just works” in VS Code and I was pleasantly surprised to find that they were right.

I expected that though. VS Code is from Microsoft, so it’s entirely expected that TypeScript would just work. What I did not expect was that virtually anything that I needed to do in VS Code “just worked” too. And I do mean anything. While this article focuses primarily on features for the web as well as JavaScript developers, VS Code has integrations with Go, Python, Java, and Ruby — just to name a few.

Over the next few months, I began to discover things in VS Code that I found remarkable. I made the official switch to VS Code, and I haven’t looked back since. Over the months I’ve been compiling a list of my favorite tips, tricks, and extensions for VS Code that might leave you with the same reaction that I had and continue to have: “VS Code can do that?!”microsoft ruby react javascript typescript

As a web developer, you know very well the need to debug your code. We often use external libraries for logs, and to format and/or display them in some cases, but the console of our browsers is much more powerful than we think.

When we think about the console, the first thing that comes to mind and the console.log, right? But there are many more methods than those we imagine. Now we will see how to make the most of using the console, and I’ll give you some tips to make them these methods more readablejavascript

Both React and Firebase are technologies that have been around for a while. 2018 has seen some exciting new developments that bring the two together in a way that’s greater than the sum of the individual parts — as awesome as they already are!

This article will show you how to build a realtime, highly scalable web app combining the two. Here’s a live demo of the result, a minimal “local Yelp clone” that lets you write reviews using your Google login:

Learn to code on your mobile device with Google Grasshopper. The app is available for Android and iOS and is aimed at teaching adults to code in JavaScript with a series of lessons in the form of quizzes and puzzles.

The Grasshopper app has a game like interface and uses game puzzles and quizzes to teach coding in JavaScript. The interface is easy to use, and the puzzles and quizzes are presented in small bites. The lessons focus on three areas:

• The Fundamentals - How code works, calling functions, variables, strings, for loops, arrays, conditionals, operators, objects, and how all these things work together.
• Animations I - Drawing shapes using the popular D3 library, defining functions, callback functions, and animations.
• Animations II - Creating more complex functions using D3 and the topics from The Fundamentals course.

IntroToRx.com is the online resource for getting started with the Reactive Extensions to .Net. Originally starting life as a blog series, it has now flourished into an online book. You can read it online here via the website, or get a copy of the Kindle edition for reading offline.

The content of the this book targets version 1.0.10621.0 of Rx (NuGet: Rx-Main v1.0.11226). This means all code samples will compile against that version. Note that Rx has shipped v2 since the release of this book. While this may initially be a concern for some readers, I would like to reassure readers that their investment in this book is still sound. All of the concepts are still valid. Virtually all of the code will still work on the latest version of Rx. The version 2.0 of Rx is largely a set of performance and portability improvements, and there are a few new features mainly around async/await support. The key things to take away from this book are the concepts. The concepts are equally applicable to v1 as they are to v2 and even transcend languages and platforms; these concepts will take you a long way in using Rx in JavaScript or even on the JVM with Java or Scala.react test javascript

So…you must have heard about ‘Flutter’ — a brand new SDK developed by Google themselves!

There was a lot of hype surrounding it as developers all around the world waited for the beta release with bated breath. Long story short, Flutter allows you to build cross-platform apps using the Dart language (Google’s own) and aims to speed up ‘Development cycles’. As with every developer(self-styled as I am only a student), I couldn’t contain my excitement and I immediately dived into the docs. From my experience, the Dart language appears to be a blend of Object-Oriented languages(like Java) and scripting languages(like JavaScript) which makes it intuitive and quite easy for people from both backgrounds’ to pick it up. Another great feature that Flutter offers is the stateful ‘Hot reload’ — Changes in code are reflected almost instantaneously while the app is running — and you can watch the changes live. This in my opinion will accelerate app development and maximize productivity (Think about all the time saved!). There is tons of information in the official docs so be sure to check it out!javascript flutter

Today, I’ll give some examples for creating forms in flutter. If you don’t know Flutter, you can start in here. The Flutter is a mobile SDK for creating mobile applications by fast. It can craft a application on iOS and Android devices with one code and this framework has full native performance!

A good news!

Flutter is in beta. Do not worry about beta because when Flutter in alpha, it used applications in production by Google. These applications downloaded and used by millions. Yes, Flutter is Google mobile UI Framework. Flutter using Dart language. It’s like Typescript or Javascript (my idea). And in the beta version, you can use Dart v2 in Flutter. I updated Flutter version in my computer using by this document. It’s easy.

Flutter has widgets for UI and we use Form and Field widgets today for creating a log in form. So first you need to look Flutter input widgets page. It has Form widget and FormField widget.news javascript typescript flutter

Flutter is a mobile App SDK by Google which helps in creating modern mobile apps for iOS and Android using a single(almost) code base. It’s a new entrant in the cross platform mobile application development and unlike other frameworks like React Native, it doesn’t use JavaScript as a Programming Language.

The programming language used by flutter is DART, which is similar to JavaScript in a way that it also runs a single threaded event queue. The biggest benefit of using Flutter is that it directly generates the ARM binaries which will execute directly on the native platform running it faster.react javascript flutter
