showModalDialog 父窗口下拉条位置记住没有记住哦，这样的代码。

showModalDialog  打开子窗口后，在关闭字窗口，父窗口的下拉条位置会跑到顶部，有没有办法记住呢。关闭子窗口，父窗口没刷新。
<script   language= "javascript ">

function newsearch(murl,width,height) //为状态提供打开页面
{
murl = encodeURI(murl);
var obj = window.showModalDialog(murl,window,"dialogWidth="+width+"px;dialogHeight="+height+"px;resizable=yes;status=no;help=no;");

//window.location.href =window.location.href; //刷新父窗口
//window.location.reload();
}
</script>
<script   language= "javascript ">
function   GetCookie   (name)
{
      var   arg   =   name   +   "= ";
      var   alen   =   arg.length;
      var   clen   =   document.cookie.length;
      var   i   =   0;
      while   (i   <   clen)
      {
              var   j   =   i   +   alen;
              if   (document.cookie.substring(i,   j)   ==   arg)
              return   getCookieVal   (j);
              i   =   document.cookie.indexOf( "   ",   i)   +   1;
              if   (i   ==   0)   break;
      }
  return   null;
}

function   getCookieVal   (offset)
{
      var   endstr   =   document.cookie.indexOf   ( "; ",   offset);
      if   (endstr   ==   -1)
          endstr   =   document.cookie.length;
          return   unescape(document.cookie.substring(offset,   endstr));
      }
function   SetCookie   (name,   value)
      {
          document.cookie   =   name   +   "= "   +   escape   (value)
      }
</script>

不用 showModalDialog  ,这个js代码，是可以控制住刷新记住下拉条位置。
怎么用到 showmodaldialog 时，也能使父窗口记住下拉条位置呢。
<script   language= "javascript ">
function   GetCookie   (name)
{
      var   arg   =   name   +   "= ";
      var   alen   =   arg.length;
      var   clen   =   document.cookie.length;
      var   i   =   0;
      while   (i   <   clen)
      {
              var   j   =   i   +   alen;
              if   (document.cookie.substring(i,   j)   ==   arg)
              return   getCookieVal   (j);
              i   =   document.cookie.indexOf( "   ",   i)   +   1;
              if   (i   ==   0)   break;
      }
  return   null;
}

function   getCookieVal   (offset)
{
      var   endstr   =   document.cookie.indexOf   ( "; ",   offset);
      if   (endstr   ==   -1)
          endstr   =   document.cookie.length;
          return   unescape(document.cookie.substring(offset,   endstr));
      }
function   SetCookie   (name,   value)
      {
          document.cookie   =   name   +   "= "   +   escape   (value)
      }
</script>
<body   bgColor= "#f1f5f5 " leftMargin= "0 " topMargin= "0 " rightMargin= "0 " MS_POSITIONING= "GridLayout " onload= "document.body.scrollTop=GetCookie( 'posy ') " onunload= "SetCookie( 'posy ',document.body.scrollTop) ">

你记住滚动条位置然后刷新之后再滚动到那个位置就可以了吧
