How to solve jQuery conflict problem

In front-end development, $ is a function in jQuery. If the parameters of $ are different, the functions implemented are different. During programming, $, as a symbol, may conflict with defined names in other files. So how do we handle this conflict? This article introduces two methods:

1. Solve the problem by releasing the right to use the $ symbol in the jQuery framework;

2. Solve using custom access symbols.

Method 1: Releasing the right to use the $ symbol in the jQuery framework

Processing instructions: $ is just an alias of jquery. If you need to use another js library other than jquery, you can return control to the library by calling $.noConflict().

jQuery.noConflict();
jQuery(function () {
   alert("hellow")
 });

Note: The release operation must be written before writing other jQuery codes, and after the release, $ cannot be used, use jQuery instead.

Method 2: Use custom access symbols to solve

Processing instructions: Customize a nj to replace the function of $

var nj =jQuery.noConflict();
nj(function(){
  alert("hello inj custom access symbol")
});
