This article shares with you the js self-executing function. Friends in need can refer to it


1 Use self-executing function To wrap the code format

APP = function(){
     var a,b; //变量a、b外部不可见
     return {
          add : function(c){
               a + b + c;
          },
          format: function(){
               //......
          }
     }
}()

2 jQuery style anonymous self-executing function


(function(window){
    //代码
 
    window.jQuery = window.$ = jQuery;//通过给window添加属性而暴漏到全局
})(window);
//通过匿名函数包装代码,所依赖的外部变量传给这个函数,在函数内部可以使用这些依赖,然后在函数的最后把模块自身暴漏给window。如果需要添加扩展,则可以作为jQuery的插件,把它挂载到$上
