Differences between anonymous functions in jQuery

Example

Differences between the two methods in jQuery

The code is as follows:

Copy code

/* Make sure that jQuery can be referenced correctly, because $ may be redefined outside the anonymous function, Passing jQuery as a parameter to an anonymous function ensures that $ in the function is jQuery. */ (Function ($ ){ // Code Here... }) (JQuery) /* $ (Document). ready () refers to a function passed to $ (). This function will be executed when DOM loading is complete. */ $ (Function (){ // Code Here... })

Most of the time,

The code is as follows:	Copy code
(Function ($ ){...}) (Jquery );

In the context environment, the parameter jquery does not exist. Therefore, in the jquery anonymous function, the user creates a jquery object.

I will give a brief description here,

The code is as follows:	Copy code
(Function ($ ){...}) (Jquery ); And A = function ($ ){...}; A (jquery );

Equivalent.

Therefore, this method is used to allow anonymous functions to be executed immediately.
