3. 支持类实例方法
添加类Person3.js 代码如下：
Ext.namespace("Ext.dojochina");
Ext.china_hongzk.Person = Ext.emptyFn; // Ext.emptyFn 等同于function(){};
Ext.apply(Ext.china_hongzk.Person.prototype,{
name: "",//为空的实例属性
sex: "",//为空的实例属性
print:function(){ //定义方法为print
//format方法 功能是参数拼接
alert(String.format("xingming:{0},xingbie:{1}",this.name,this.sex));//方法体
}
});然后再在Person3.aspx 页面里调用 Person3.js类 代码如下：
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>类实例方法</title>
<link rel="stylesheet" type="text/css" href="../ext-2.0.2/resources/css/ext-all.css" />
<script src="../ext-2.0.2/adapter/ext/ext-base.js" type="text/javascript"></script>
<script src="../ext-2.0.2/ext-all.js" type="text/javascript"></script>
<script src="Person3.js" type="text/javascript"></script>
<script type="text/javascript" language="javascript">
var _Person = new Ext.china_hongzk.Person(); //实例对象
_Person.name = "hongzhikang";
_Person.sex = "nan";
_Person.print();
//再次赋值
_Person.name = "洪志康";
_Person.sex = "男";
_Person.print();
</script>
</head>
<body>
<form id="form1" runat="server">
<div> </div>
</form>
</body>
</html>
