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
<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>
