Is jquery native?

JQuery is an acronym for js+query, which can be understood as encapsulating a lot of methods on the basis of native js and creating a library of js.

Introduction to jquery:

JQuery is a fast and concise JavaScript framework, which is another excellent JavaScript code base (framework) released by John Resig in January 2006 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.

The difference between native js and jquery:

1. Native js and jquery entry function loading modes are different

two。 Native js waits until the dom element is loaded and the picture is loaded; jquery waits until the dom element is loaded, but not until the picture is loaded

3. On the problem of function coverage, when native js writes multiple entry functions, what is written later will overwrite what was written earlier; jquery will not overwrite but execute sequentially
