Multiple layers of jquery's anonymous method and multiple layers of jquery's anonymous method

Anonymous method:

(Function (x) {}) (3 );

Explanation: the first () is a method, and the second () is a parameter in the method.

Purpose: The anonymous method is automatically executed in javascript. For example, the start method of jquery can be written as an anonymous method:

(Function ($) {}) (jQuery); // The second parameter is the object name in the jquery file you call.

Multi-layer calls to anonymous methods:

<Script type = "text/javascript">

(Function ($ ){

Var tt = (function (){

Var module = {
Shop :( function (){
Var sub = {
Buy: function (x ){

Return x + 8;
}
};
Return sub;

})(),

};
Return module;

 

})();
Console. log (tt. shop. buy (3 ));

}) (JQuery );
</Script>
