window.opener在Firefox中为null [英] window.opener is null in firefox

问题描述

我有一个打开弹出窗口的页面

  openWindow（top，'prcsTypeSelectionPopup？event = prcsTypeSelection'，'lovWindow '，{width：750，height：550}，true，'dialog'，pathCallBack）; 
  

，弹出窗口有以下代码：

 函数returnSelect（）
 {
 window.document.forms [0] .choice_processType.value; 
 window.opener.document.forms [0] .pevent.value ='getprocessName'; 
 window.opener.document.forms [0] .processName.value =''; 
 for（var i = 0; i< document.forms [0] .elements.length; i ++）
 {
 if（document.forms [0] .elements [i]。已检查）
 {
 window.opener.document.forms [0] .processName.value = document.forms [0] .elements [i] .value; 
 break; 
 
 $ b $ if（window.opener.document.forms [0] .processName.value ==''）{
 window.opener.document.forms [0] .lovProcessType.value =''; 
 window.opener.document.forms [0] .pevent.value =''; 
 
 window.opener.document.forms [0] .submit（）; 
 closeConn（）; 
 
 
函数closeConn（）
 {
 self.close（）; 
} 
  

但是当页面在firefox中加载时，出现
window.opener在returnselect（）函数的第二行是空的

$ p $函数returnSelect（）
{
window.document.forms [0] .choice_processType.value;
- > window.opener.document.forms [0] .pevent.value ='getprocessName';

任何想法如何克服这个

在此先感谢...

解决方案

它只适用于parent.window.opener而不适用于window.opener

感谢Sergzach你的时间

I have a page which opens the popup as

openWindow(top, 'prcsTypeSelectionPopup?event=prcsTypeSelection', 'lovWindow', {width:750, height:550}, true, 'dialog', pathCallBack);

and the popup has the following code

function returnSelect()
{
    window.document.forms[0].choice_processType.value ;
    window.opener.document.forms[0].pevent.value = 'getprocessName';
    window.opener.document.forms[0].processName.value='';
    for (var i=0; i < document.forms[0].elements.length; i++)
   {
   if (document.forms[0].elements[i].checked)
      {
      window.opener.document.forms[0].processName.value=document.forms[0].elements[i].value;
      break;
      }
   }
   if(window.opener.document.forms[0].processName.value=='')    {
        window.opener.document.forms[0].lovProcessType.value = '';
        window.opener.document.forms[0].pevent.value = '';
   }
    window.opener.document.forms[0].submit();
    closeConn();
}

function closeConn()
{
         self.close();
}

But when the page is loaded in firefox, am getting the error as window.opener is null at the 2nd line of returnselect() function

function returnSelect()
    {
        window.document.forms[0].choice_processType.value ;
        --> window.opener.document.forms[0].pevent.value = 'getprocessName';

Any idea how to overcome this

Thanks in advance...

解决方案

it works only for "parent.window.opener" and not for "window.opener"
