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>

        }
        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
