父页面关闭子页面问题..帮我看一下..10分钟等待.

主要是弹出的   页面点关闭   无法关闭   我不知道是不是页面机制的问题..请朋友帮我看看...谢谢


页面:
<script   language= "JavaScript "   type= "text/JavaScript ">
  //消息提醒机制
  function   reply(data){
        //判断数据的状态   如果有新的数据则调用ringPlay();
        if(data   !=0){
              popmsg(data);
        }
  }
 
  function   check(){
      //调用系统的查询数据
//       QueryMessageAjaxHelper.getNewDocPub(reply);
      var   data   =   10
      popmsg(data);
      //设置循环时间
      setTimeout( "check() ",6000);
  }

  //根据不同的参数调用页面的声音提醒文件
  function   ringPlay(){
      document.getElementById( "ring ").play();
  }
 
  function   closeDiv(){
      //document.getElementById( 'eMeng ').style.visibility= 'hidden ';
      //if(objTimer)   window.clearInterval(objTimer)
      alert( "aaaa ");
  }
 
  var   oPopup   =   window.createPopup();
  var   popTop=50;
 
function   popmsg(msgstr){
var   winstr   =   " ";
winstr+= " <TABLE   style=\ "BORDER-TOP:   #ffffff   1px   solid;   BORDER-LEFT:   #ffffff   1px   solid\ "   cellSpacing=0   cellPadding=0   width=\ "100%\ "   bgColor=#cfdef4   border=0> ";
