Question

我在网上找到了一些javascript代码。我正在使用它，但在这里我无法获得windows.alert（）方法。以下是我的代码。

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Javascriptexmple.aspx.cs"     Inherits="MIS_Javascriptexmple" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<script language="javascript" type="text/javascript">
  function Validate() {
      // Get the password entered in the page
      var Pass = $get("MyPass").value;
      // Encrypte the password
      var MD5 = hex_md5(Pass);
      // Run ValidateLogin PageMethod to validate the password
      PageMethods.ValidateLogin(MD5, Done);
      window.alert(MD5);
  }
  function Done(result) {
      // Alert the boolean result returned from PageMethod
      alert(result);
  }
  </script>
<title></title>
</head>
<body>
<form id="form1" runat="server">
    <asp:ScriptManager EnablePageMethods="true" ID="ScriptManager1" runat="server">
    <Scripts>
      <asp:ScriptReference Path="md5.js" />
    </Scripts>
  </asp:ScriptManager>

<div>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
    <ContentTemplate>
      <asp:TextBox ID="MyPass" runat="server"></asp:TextBox>
      <input id="BtnLogin" type="button" value="Login" onclick="Validate();" />
    </ContentTemplate>
  </asp:UpdatePanel>
</div>
</form>

请让我知道我失踪的地方？

$get未定义。 hex_md5未定义。 PageMethods.ValidateLogin未定义。包括定义这些功能的脚本，你应该好好去。像这样：

<script src="md5script.js" type="text/javascript"></script>
<script language="javascript" type="text/javascript">
  function Validate() {
      // Get the password entered in the page
      var Pass = $get("MyPass").value;
      // Encrypte the password
      var MD5 = hex_md5(Pass);
      // Run ValidateLogin PageMethod to validate the password
      PageMethods.ValidateLogin(MD5, Done);
      window.alert(MD5);
  }
  function Done(result) {
      // Alert the boolean result returned from PageMethod
      alert(result);
  }
  </script>

javascript中的Window.Alert（）无效
