Summary of js object creation methods, js object Creation

This example summarizes how js creates objects. Share it with you for your reference. The details are as follows:

Copy codeThe Code is as follows:
<Script type = "text/javascript">
// 1. Create an object using the Literal Value
Var obj = {holobby: 'basketball ', girlf: 'beauty '};
Document. write (obj. Hoby + 'and' + obj ['girlf ']);
// 2. Create an Object using the new Object method. The Object is the built-in constructor of the system.
Var obj2 = new Object ({holobby: 'basketball ', girlf: 'beauty'}); // if no parameter is added, an empty Object is returned. This creation method is not required

// 3. self-built constructor methods, which are consistent with the 2nd methods. The difference is that 2nd types of objects come with the system, and they are created for themselves here.
Function Dog (){
This. leg = 4;
This. bark = function (){
Alert ('wang ...');
};
}
Var obj3 = new Dog ();
Alert (obj3.leg );
</Script>
