Author: User

I hope you can provide more support.
I,AddScriptmanagerControl.

II,Register a namespace:

Type. registernamespace ("Demo ");

 

III,Add constructors, attributes, and methods to the class.

Demo. Sample = function (){}

IV,Registration type.

Demo. Person. registerclass ('demo. sample', null, SYS. idisposable)

The following is an example:

Namespace. js

Type. registernamespace ("Demo ")

Demo. Person = function (firstname, lastname, emailaddress ){

This. _ firstname = firstname;

This. _ lastname = lastname;

This. _ emailaddress = emailaddress;

}

Demo. Person. Prototype = {

Getfirstname: function (){

Return this. _ firstname;

}

Getlastname: function (){

Return this. _ lastname;

},

 

Getname: function (){

Return this. _ firstname + ''+ this. _ lastname;

},

Dispose: function (){

Alert ('bye' + this. getname ());

}

}

Demo. Person. registerclass ('demo. person', null, SYS. idisposable );

 Namespace. aspxCode:

<! Doctype HTML public "-// W3C // dtd xhtml 1.0 transitional // en"
