(编辑：jimmy 日期: 2024/10/15 浏览：2)
由于 Microsoft AJAX Library 对于 JavaScript 进行了大幅扩展，
枚举这个常用的功能当然也被加进去了，
本次就是来探讨 JavaScript 的枚举功能。
由于范例很简单，
所以直接看 HTML 标签就 OK 了
复制代码 代码如下:
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<script language="javascript" type="text/javascript">
Type.registerNamespace("BaoBeiMe");
//注册一个枚举
BaoBeiMe.EnumDepartment = function() {
}
BaoBeiMe.EnumDepartment.prototype = {
One: "信息部",
Two: "业务部",
Three: "财务部",
Four: "研发部"
}
BaoBeiMe.EnumDepartment.registerEnum("BaoBeiMe.EnumDepartment");
function Button1_onclick() {
var enumDepartment = new BaoBeiMe.EnumDepartment();
var lblMsg = $get('<%=lblMsg.ClientID %>');
lblMsg.innerText = "One 是 " + enumDepartment.One + " , " +
"Two 是 " + enumDepartment.Two + " , " +
"Three 是 " + enumDepartment.Three + " , " +
"Four 是 " + enumDepartment.Four + " ";
}
</script>
<div>
<input id="Button1" type="button" value="获取所以枚举值"
onclick="return Button1_onclick()" /><br />
<br />
<asp:Label ID="lblMsg" runat="server" Text=""></asp:Label>
</div>
</form>
</body>
</html>
结果
