先看aspx： 复制代码 代码如下:
先看aspx：
<!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">
<title>petter liu demo</title>
<script src="http://img.jb51.net/jslib/jquery/jquery14.js" type="text/javascript"></script>
<script type="text/javascript">
$(function() {
$("input:submit").click(function() {
$("#hiddenfield1").val($(this).attr("id")
+ " 引起一个 postback");
});
});
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:button id="button1" runat="server" text="button1" />
<asp:button id="button2" runat="server" text="button2" />
<asp:button id="button3" runat="server" text="button3" />
<asp:hiddenfield id="hiddenfield1" runat="server" />
</div>
</form>
</body>
</html>
然后在sever端这么写：
/// <summary>
/// handles the load event of the page control.
/// </summary>
/// <param name="sender">the source of the event.</param>
/// <param name="e">the <see cref="system.eventargs"/> instance containing the event data.</param>
/// <remarks>author petter liu http://wintersun.cnblogs.com </remarks>
protected void page_load(object sender, eventargs e)
{
response.write(hiddenfield1.value);
}
很简单的code.
