JS Object-oriented constructors

The simplest object-oriented program
<script type= "Text/javascript" >    varnew  Object ();     = ' 1079161148 ';     = ' Mr Lan '    function() {        alert (this. Name)    }     function() {        alert (this. QQ)    }    obj.showname ()    OBJ.SHOWQQ ()</script>

the method of encapsulation reuse;
<script type= "Text/javascript" >functionCreateperson (name, QQ) {//The constructor constructs an object;        varobj =NewObject (); OBJ.QQ=QQ; Obj.name=name Obj.showname=function() {alert (' My name = ' + This. Name)} OBJ.SHOWQQ=function() {alert (' My QQ = ' + This. QQ)} //Factory        returnobj}varobj = Createperson (' Mr Lan ', ' 1079161148 '); varObj2 = Createperson (' Mr Li ', ' 1079161168 ');    Obj.showname (); OBJ.SHOWQQ ();</script>

//Upgrade-------> constructor call plus new
<script type= "Text/javascript" >functionCreateperson (name, QQ) {//The constructor constructs an object;         This. QQ =QQ;  This. Name =name This. ShowName =function() {alert (' My name = ' + This. Name)}  This. SHOWQQ =function() {alert (' My QQ = ' + This. QQ)} }    varobj =NewCreateperson (' Mr Lan ', ' 1079161148 '); varObj2 =NewCreateperson (' Mr Li ', ' 1079161168 '); Obj.showname () obj.showqq ()

Alert (obj.showname () = =Obj2.showname ())//false

</script>

//Advanced Object-oriented programming
<script type= "Text/javascript" >//Mixed constructor Blending (constructor mate prototype)    functionCreateperson (name, QQ) {//Constructors Plus Properties         This. QQ =QQ;  This. Name =name} createPerson.prototype.showName=function(){//prototype Plus methodAlert (' My name = ' + This. Name)} CreatePerson.prototype.showQQ=function() {alert (' My QQ = ' + This. QQ)} varobj =NewCreateperson (' Mr Lan ', ' 1079161148 '); varObj2 =NewCreateperson (' Mr Li ', ' 1079161168 '); //obj.showname ()//can also continue to be used without affecting the use of    //obj.showqq ()Alert (obj.showname () = =obj2.showname ())//true</script>
