我已經在一個aspx的ASP按鈕：ASP.NET Web表單 - 調用C＃方法與AJAX
<asp:Button id="btnReport2" name="btnReport2" runat="server" class="gradientBlueBtn" Text="Show Report" OnClientClick="Alert();" ToolTip="Report"/>
正如你所看到的，我打電話給它使用AJAX調用C＃中的javascript函數方法。我這樣做：
<script>
function Alert()
{
$.ajax({
type: "POST",
url: "Selection.aspx/GetReport",
contentType: 'application/json; charset=utf-8',
dataType: 'json',
success: function()
{
alert('success');
},
error: function()
{
alert('error');
}
});
}
</script>
事情是，我總是收到錯誤信息，當我點擊按鈕。有什麼我做錯了嗎？
編輯：C＃方法。我已經設置了一個斷點來查看該方法是否被調用，但顯然不是。

添加錯誤消息，將是有益的。 –
請爲您的＃GetReport方法添加c＃代碼 –
