The three most common methods of JS object definition

Defining objects: The combination of properties and methods (combinations of variables and functions)
1. (* * *) var obj = {}

2.var obj = new Object ();

3. Defining objects with function

Specific examples are:

1 //1. Defining an Obj Object2 //obj: Object name3 var obj = {4 //Height,weight,sex properties called Objects5 height:170,//use, separating properties and methods6 weight:90,7 sex: ' BBW ',8 9 //Say (): Method called ObjectTen say:function () { One alert (' 付帅帅, you have a long handsome '); A         }, - eat:function () { - alert (' eat '); the         } -     } -  - //Gets the object's properties (object name. Property name) + Console.log (obj.weight); - //method of the Calling object (object name. Method Name ()) +Obj.say ();

1 //2. Defines an empty object2 var O1 = new Object ();3 //Assigning properties to an object4 o1.height = ' 150cm ';5 o1.color = ' Silver ';6 O1.fire = function () {7 alert (' Chop it, when firewood Burns ');8     }9 Ten //Call One Console.log (o1.height); AO1.fire ();

3. Use the function to define    the Object function demo () {        //This represents the current object        this.memory = ' 16G ';        This.hard = ' 1T ';        This.ys = function () {            alert (' The computer is doing a high-load operation at this moment ');}    }    Call (Instantiate demo () function)    var d = new demo ();    Console.log (d.memory);    D.ys ();
