Introduction to jquery events and functions _ jquery

Jquery events and functions are frequently used. This article describes event binding, function declaration, and naming function expressions. For more information, see 1. Bind events

Method 1:

This method can be used to add events to elements during page loading.

The Code is as follows:

$ ("# MyElement"). click (function (){
Alert ($ (this). text ());
})

Method 2:

Like 1, you can add events to elements after loading a page, such as creating a new DOM element.

The Code is as follows:

$ ("# MyElement"). bing ('click', function (){
Alert ($ (this). text ());
})

2. function declaration and naming function expressions

Function declaration:

The Code is as follows:

Function myFun1 (){
$ ("P"). hide ();
}

Call: myFun1 ();

Function expression:

The Code is as follows:

Var myFun2 = function (){
$ ("P"). hide ();
}

Call: # ("# myElement"). click (myFun2 );

Differences:The difference between the call time and the function declaration can be used anywhere. The name function expression can only be used after the declaration.
