一、为页面添加一个ScriptManager控件。
二、注册命名空间：
Type.registerNamespace("Demo");
三、为类添加构造函数、属性、方法。
Demo.sample=function(){}
四、注册类。
Demo.Person.registerClass('Demo.sample',null,Sys.IDisposable);
下面是一个具体的实例：
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(){
returnthis._firstName;
},
getLastName:function(){
returnthis._lastName;
},
getName:function(){
returnthis._firstName+''+this._lastName;
},
dispose:function(){
alert('bye'+this.getName());
}
}
Demo.Person.registerClass('Demo.Person',null,Sys.IDisposable);
Namespace.aspx代码：
<!DOCTYPEhtmlPUBLIC"-//W3C//DTDXHTML1.0Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<htmlxmlns="http://www.w3.org/1999/xhtml">

'John','Smith','john.smith@example.com');
alert(testPerson.getFirstName()+""+
testPerson.getLastName());
returnfalse;
}
</script>
