Xiaobian to share with you what types of jquery library, I believe most people do not know how, so share this article for everyone's reference, I hope you have a lot of harvest after reading this article, let's go to understand it together!

There are two types of jquery library: 1. The production version "jquery.min.js" is mainly used for products and projects after being compressed by tools or gzip by server opening;2. The development version "jquery.js" is mainly used for testing, learning and development.

This tutorial operates on Windows 7, jquery version 1.10.2, Dell G3 computers.

jQuery is a fast, concise JavaScript framework, another excellent JavaScript codebase (framework) after Prototype, released by John Resig in January 2006. jQuery is designed to "write Less, Do More," which means write less code and do more. It encapsulates JavaScript's commonly used functional code and provides a simple JavaScript design pattern that optimizes HTML document manipulation, event handling, animation design, and Ajax interaction.

The core features of jQuery can be summarized as follows: unique chain syntax and short and clear multifunctional interface; efficient and flexible CSS selector, and CSS selector can be extended; convenient plug-in extension mechanism and rich plug-ins. jQuery is compatible with all major browsers, such as IE 6.0+, FF 1.5+, Safari 2.0+, Opera 9.0+, etc.

JQuery library types are divided into several types

There are two types of jquery libraries: production version (jquery.min.js) and development version (jquery.js).

The development version is mainly used for testing, learning and development.

The production version is compressed by tools or server open gzip, mainly for products and projects.

These two libraries do not need to be installed, just put in the corresponding directory, when a page needs to use jquery, just need to introduce the location of the library file in the relevant html document. You can write in html:

Advantages of jQuery

1. Lightweight: Compressed to only about 30KB.

2. Powerful selectors: jQuery allows almost all selectors from CSS1 to CSS3 as well as its own original selectors.

3. Excellent DOM manipulation encapsulation: jQuery encapsulates a large number of commonly used DOM manipulations, which is handy for developers when writing DOM manipulation-related programs.

4. Reliable event handling: The jQuery event handling mechanism is fairly reliable when handling event bindings.

5. Perfect Ajax: jQuery encapsulates all Ajax operations in a function called $.ajax(), allowing developers to focus on business logic when dealing with Ajax without having to worry about complex browser compatibility and the creation and use of XMLHttpRequest objects.

6. Do not pollute top-level variables: jQuery creates only one object named jQuery, and all its function methods are under this object. Its alias $can also surrender control at any time, never contaminating other objects.

7. Excellent browser compatibility: jQuery fixes some browser differences, so developers don't have to build browser compatibility libraries before launching projects.

8. Chain operation mode: jQuery is the most distinctive way of chain operation-that is, a group of actions that occur on the same jQuery object can be directly linked without repeatedly obtaining the object.

9. Implicit iteration: When jQuery finds all elements with a ".myClass" class and hides them, there is no need to loop through each returned element.

10. Separate the behavior layer from the structure layer: Developers can select elements using the jQuery selector and add events directly to the elements.

11. Rich plug-in support: jQuery's extensibility attracts developers from all over the world to write jQuery extensions.

12. Perfect documentation: jQuery documents are very rich, whether it is Chinese documents or English documents.

13. Open Source: jQuery is an open source product.
