<title></title>
<script type="text/javascript">
function ChangeCode() {

var date = new Date();
var myImg = document.getElementById("ImageCheck");

myImg.src = "../ValidateCode.aspx?GUID=" + GUID.innerHTML + "&flag=" + date.getMilliseconds()

return false;
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
驗(yàn)證碼：
<input class="nemo01" id="CheckCode" tabindex="3" maxlength="22" size="11" name="user"
runat="server">
<a id="A2" href="" onclick="ChangeCode();return false;">
<asp:Image ID="ImageCheck" runat="server" ImageUrl="../ValidateCode.aspx?GUID=GUID"
