JavaScript creates class objects

The right example:

var person=function (name,age) {this      . Name= ";      This. Age= ";      This. Say=function (msg) {             alert (msg);      }      This.init=function (name,age) {this             . Name=name;             This. age=age;      }      This.init (name,age);      var fun=function () {            alert (' fun ');      }      This.funshow=function () {fun             ();      }

      <pre name= "code" class= "HTML" >      var mutilfun=function () {             <pre name= "code" class= "HTML" >             Say ();

<span style= "font-family:arial, Helvetica, Sans-serif;" > This                          . Say ();</span>

}

      This.mutilfunshow=function () {          <pre name= "code" class= "HTML" >             mutilfun ();

}

Fun ();} Call: Var jon=new person (' Jon ', 26); Jon.say (' Go away '); Alert (jon.name+jon.age), above all to Var shaw=new person (' Shaw ', 26);

   Shaw.fun ();

<pre name= "code" class= "HTML" >   shaw.funshow ();//This is right. Other Shaw is wrong.

   Shaw.mutilfunshow ();//This inside is capable of running to mutilfun this culvert, but <span style= "font-family:arial, Helvetica, Sans-serif;" >mutilfun this number of errors, because Mutilfun in This.say () is not the person in this class This.say (). This here refers to the                                                   </span><span style= "font-family:arial, Helvetica, Sans-serif;" >mutilfun, not person. </span>

Shaw, this object is wrong.

Why Shaw.fun () will be wrong, and the reported error isShaw.fun () is not a function. Because fun is not a property of Shaw, if the attribute is not var;

But Shaw.funshow () is right.

a person is a class and a method, and it is more appropriate to say the method with attributes. Person inside is also step by step execution pull down, first run this.init (name,age), in Run Fun ().
