scrollTop无效。 [英] scrollTop is not working.

问题描述

我有一个以模态弹出方式打开的用户控件。在用户控件内部，我有一个面板和网格。我希望在回发后保持网格的滚动位置。我想用javascript做这件事。这是我的代码 -  

I have a user control that open in modal pop up. Inside the user control i have a panel and Grid. I want to maintain the scroll position of grid after postback. i am trying to do this with javascript. Here is my code - 

< script type =" text / javascript" language =" javascript">

  &NBSP; var test;

  &NBSP; Sys.WebForms.PageRequestManager.getInstance（）。add_beginRequest（beginRequest）;

  &NBSP; Sys.WebForms.PageRequestManager.getInstance（）。add_endRequest（endRequest）;
$


  &NBSP; function beginRequest（sender，args）{

  &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; var m = document.getElementById（'OrderSelector1_pnlGridView'）;

  &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; test = m.scrollTop;



  &NBSP; }¥b $ b  &NBSP; function endRequest（sender，args）{

  &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; var m = document.getElementById（'OrderSelector1_pnlGridView'）;

  &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; m.scrollTop = test;



  &NBSP; }
< / script>

<script type="text/javascript" language="javascript">
    var test;
    Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(beginRequest);
    Sys.WebForms.PageRequestManager.getInstance().add_endRequest(endRequest);

    function beginRequest(sender, args) {
                var m = document.getElementById('OrderSelector1_pnlGridView');
                test = m.scrollTop;

    }
    function endRequest(sender, args) {
                var m = document.getElementById('OrderSelector1_pnlGridView');
                m.scrollTop = test;

    }
</script>

我在var" test"中获取值但是在endRequest函数中，当我将值放回m.scrollTop时，它似乎无法正常工作。它始终显示为0。

I am getting the value in var "test" but in the endRequest function when i am putting back the value in the m.scrollTop, it seems it is not working. It shows always 0.
