每次我在IE8Version中展开和折叠树视图时都会询问确认消息。

问题描述

嗨

在我的网页上，当我离开页面并浏览新页面时，我会显示确认消息。它工作正常。但我的一个页面有树视图。在该页面上，每次我展开和折叠树视图时都会询问确认消息。我们如何避免它。请帮我解决这个问题。

我的编码是

Hi
In my webpage, I show confirm message when I leave the page and navigate new page. It is working fine. But one of my page has treeview. On that page only every time I expand and collapse treeview It asks confirmation message. How we avoid it. Please help me, for this problem.
My coding is

<script type="text/javascript" language="javascript">
       window.onbeforeunload = function () {
          
           if (document.getElementById("<%=hdnSavingMode.ClientID %>").value.toUpperCase() == 'TRUE') {
               return "Do you want to leave this page without saving?";

           }
       };
    </script>

只有IE不在Firefox中。我正在使用IE 8版本。

It happens only IE not in firefox. I am using IE 8 version.
