JQuery is a cross-browser JavaScript library that simplifies operations between HTML and JavaScript. The following is a description of jQuery on Wikepedia: jQuery is an open-source software and is authorized using the MIT license. [4] jQuery syntax design makes many operations easy, such as operating document objects, selecting DOM elements, Creating Animation effects, processing events, and developing Ajax programs. JQuery also provides developers with the ability to create plug-ins on them. This allows developers to abstract underlying interaction and animation, advanced effects, and advanced theme components. The modular approach enables the jQuery function library to create powerful dynamic web pages and network applications. JQuery has the following features: DOM inspection and modification for cross-browser DOM elements: supports CSS 1-3 and basic XPath. After jQuery 1.2, XPath support will be canceled by default, and plug-in support Events (Events) will be changed) CSS controls special effects and animations (move the display position, fade in, fade out). Ajax Extensibility tools include browser versions and each functions. JavaScript plug-in is lightweight. Many application development frameworks have integrated jQuery, such as the PHP Yii Framework and Java EE Vaadin Web application development Framework described earlier, these frameworks can use jQuery's UI functions using PHP or Java instead of JavaScript. But learning about jQuery JavaScripts programming is still very helpful for better compiling Web pages. Microsoft and Nokia have announced that they will bind jQuery to their platforms. [5] Microsoft initially integrated jQuery [6] in Visual Studio for use in Microsoft's ASP. net ajax Framework and ASP. net mvc Framework. Therefore, if you are engaged in ASP. Net, Sharepoint Web Part, or Application Page development, it is particularly important to understand jQuery. This tutorial helps beginners understand basic jQuery development and lay a solid foundation for further learning other Web programming. This tutorial uses Visual Studio as a development tool, you can also use your favorite development IDE, Visual Studio supports Javascript debugging, jQuery uses the latest version of jquery-1.9.1.js. Download to local. Using Visual Studio to create a Website, put the downloaded jquery-1.9.1.js in the default.html of the scripts repository with the following code framework as the basis for subsequent examples: [html] <! Doctype html>
