Running AJAX function in parent window from child

[jack21]

I have a main window containing a list of items along with some buttons. If the user clicks the 'View' button, I open a child window containing the details of the item along with 'Approve' and 'Reject' buttons.

What I'm trying to do is if the user presses the 'Approve' button on the child window, then the parent window is updated via an AJAX function within the parent's <SCRIPT> tags and the child window is closed.

I've tried running the parent function from the child window via window.opener.l oadApprovalList () (which does run) but it returns an error stating '[Exception... "Component returned failure code: 0x80040111 (NS_ERROR_NOT_A VAILABLE) [nsIXMLHttpReque st.status]" nsresult: "0x80040111 (NS_ERROR_NOT_A VAILABLE)" location: "JS frame :: http://localhost/cgi-bin/functions.js :: parseApprovalLi st :: line 171" data: no]

Any ideas what's going on?

Welcome to TSDN!

Post the code for loadApprovalLis t().

I've narrowed the problem down to this:

it appears that once I perform a document.x.subm it() and then try to do an xmlhttp.open, the browser (only tested with FF at this juncture) does a submit().

Anyway, here is the relevant code:

function postDoc(data,func)
{ 
  var url='/cgi-bin/ajax.js';
 
  // Mozilla, etc.
  if (window.XMLHttpRequest)
  { xmlhttp=new XMLHttpRequest();
    xmlhttp.onreadystatechange=func;
    xmlhttp.open("POST",url,true);
    xmlhttp.setRequestHeader('Content-Type','application/x-www-form-urlencoded');
    xmlhttp.send(data);
  }
  // IE
  else if (window.ActiveXObject)
  { xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
    if (xmlhttp)
    { xmlhttp.onreadystatechange=func;
      xmlhttp.open("POST",url,true);
      xmlhttp.setRequestHeader('Content-Type','application/x-www-form-urlencoded');
      xmlhttp.send(data);
    }
  }
}
 
function loadApprovalList()
{
  postDoc('function=listApprovals',parseApprovalList);
}
 

Note: I'd post the parseApprovalLi st function, but it never gets called!

The error is in parseApprovalLi st, line 171.
