The Script tag is placed incorrectly in your markup. 脚本标记未正确放置在您的标记中。
Try this 尝试这个
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="ReportViewer.aspx.cs" Inherits="stackoverflow1.ReportViewer" %> <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <script type ="text/javascript" src="http://code.jquery.com/jquery-1.10.1.min.js"></script> <script type ="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script> <script type="text/javascript"> function CleanUpSession() { $.ajax({ type: "POST", url: "ReportViewer.aspx/CleanUp", contentType: "application/json; charset=utf-8", dataType: "json", data: "{}", error: function (XMLHttpRequest, textStatus, errorThrown) { alert("Request: " + XMLHttpRequest.toString() + "\\n\\nStatus: " + textStatus + "\\n\\nError: " + errorThrown); }, success: function (result) { alert("We returned: " + result); } }); } </script> <title></title> </head> <body> <button OnClick="CleanUpSession();">test</button> </body> </html>

Solved my problem. 解决了我的问题。 Just used asp:button instead of simple button and ajax 只是使用asp：button而不是简单的button和ajax
<body onbeforeunload="CleanUpSession();">
<script type="text/javascript">
function CleanUpSession() {
var item = document.getElementById('<%=ButtonCleanUp.ClientID%>');
if (item != null)
item.click();
}
</script>
<form id="form1" runat="server">
<asp:Button ID="ButtonCleanUp" OnClick="CleanUp_Click" Text="Button Text" runat="server"/>
</form>
</body>
