JS method to implement dynamic sequential loading of files_javascript skills

The example in this article describes the method of dynamic sequential loading of files using JS. Share it with everyone for your reference. The specific analysis is as follows:

Use script tags to dynamically load JS code.

Derived from the feature of JavaScript language that definitions of functions, variables, etc. can be declared repeatedly (leading to overwriting), and are loaded in order.

The implementation is based on the Mootools framework and is compatible with IE, Firefox, and Chrome.

Usage is as follows:

<script language="javascript"> 
  window.addEvent('domready', function() { 
    // 载入器声明，成员函数 include 载入文件
    new JsLoader(function() {
      // 载入后完毕的回调函数定义
    }, null).include([
      // 待载入文件列表（数组） 
    ]); 
     // 也可保存该对象，调用 callback 重新赋值回调函数 
    // 并导入新的文件 
  });
</script>

I hope this article will be helpful to everyone’s JavaScript programming design.
