asp.net 后面获取Label值的问题
- C# code
<html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"> <title></title> <script src="js/jquery-1.4.1.js" type="text/javascript"></script> <script type="text/javascript"> $(function () { $("#Button1").click(function () { var sumall = 33; $("#Label14").text(sumall); }) }) </script></head><body> <form id="form1" runat="server"> <div> <input id="Button1" type="button" value="button" /> <asp:Label ID="Label1" runat="server"></asp:Label> </div> </form></body></html>在后台用Label1.Text获取的值为空的，为什么呢？
[解决办法]
例子
<%@ Page Language="C#" %>
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
if (Request.RequestType == "POST")
{
Response.Write(HiddenField1.Value);
}
}
</script>
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title></title>
<script src="jquery-1.7.1.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(function () {
$("#Button1").click(function () {
var sumall = 33;
$("#Label14").text(sumall);
$("#HiddenField1").val(sumall);
$("#form1").submit();
})
})
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<input id="Button1" type="button" value="button" />
<asp:Label ID="Label1" runat="server"></asp:Label>
<asp:HiddenField ID="HiddenField1" runat="server" />
</div>
</form>
</body>
</html>
