1. Bind events
Method 1:
This method can be used to add events to elements during page loading.
Copy codeThe 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.
Copy codeThe Code is as follows:
$ ("# MyElement"). bing ('click', function (){
Alert ($ (this). text ());
})
2. function declaration and naming function expressions
Function declaration:
Copy codeThe Code is as follows:
Function myFun1 (){
$ ("Div"). hide ();
}
Call: myFun1 ();
Function expression:
Copy codeThe Code is as follows:
Var myFun2 = function (){
$ ("Div"). 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.
