This will bring your programming habits and ideas closer to jquery. Because jquery still has defects, so after learning to a certain extent, you can also try to understand the source code of jquery and explore the principle of jquery fundamentally. Become a real talent.

Extended data

JQuery is a fast and concise JavaScript framework, and it is another excellent JavaScript code base (or JavaScript framework) after Prototype. JQuery is designed to be "write Less,Do More", which advocates writing less code and doing more. It encapsulates the common functional code of JavaScript, provides a simple JavaScript design pattern, and optimizes HTML document operation, event handling, animation design and Ajax interaction.

The core features of jQuery can be summarized as follows: unique chain syntax and short and clear multi-function interface; efficient and flexible css selector, which can be extended to CSS selector; convenient plug-in extension mechanism and rich plug-ins. JQuery is compatible with a variety of mainstream browsers, such as IE 6.0 +, FF 1.5 +, Safari 2.0 +, Opera 9.0 + and so on.

JQuery's selection mechanism is built on Css's selector, which provides the ability to quickly query elements in DOM documents and greatly strengthens the way page elements are retrieved in JavaScript.

Provide beautiful dynamic effects on the page

JQuery has a series of built-in animation effects to develop very beautiful web pages, and many websites use jQuery's built-in effects, such as fade in and out, element removal and other dynamic effects.

Create an AJAX web page without refresh

AJAX is the abbreviation of asynchronous JavaScript and XML, which can develop very sensitive web pages without refresh, especially when developing server-side web pages, such as PHP websites, need to communicate with the server back and forth, if you do not use AJAX, every data update has to refresh the web page, and after using AJAX special effects, the page can be partially refreshed to provide dynamic effects.

Provides enhancements to the JavaScript language

JQuery provides enhancements to basic JavaScript structures, such as element iteration and array processing.

Enhanced event handling

JQuery provides a variety of page events that prevent programmers from adding too much event handling code to HTML, and most importantly, its event handler eliminates various browser compatibility issues.

Change the content of a web page

JQuery can modify the content of a web page, such as changing the text of a web page, inserting or flipping a web page image, and jQuery simplifies the way it would have to be handled with JavaScript code.
