I've been working on a Firefox extension, and I'm having trouble with a particular javascript function.

code:

function GetStatus(timeout) {
  var sreq = new XMLHttpRequest();
  sreq.onreadystatechange = function (aEvt) {
    if (sreq.readyState == 4) {
      if(sreq.status == 200) {
	    var img = document.write("http://url.com/Smileys/sa/" + sreq.responseText);
        document.getElementById("WOPR-ImgLeft").value = img;
		document.getElementById("WOPR-ImgRight").src = "http://url.com/Smileys/sa/goonpatriot.png";
      }
    }
  };
  sreq.open('GET', URL()+'/toolbar_status.php', true);
  sreq.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
  sreq.send(null);
  if (timeout) {
    setTimeout ("GetStatus()", 1000*60*30);
  }
}

The function is supposed to recursively call itself every 30 minutes (it does), retrive the image name from toolbar_status.php (it does) and point two images that appear in the toolbar to it.

I have tried multiple combinations of document.getElementById(image id).value and .src with combinations of the above image options (document.write("http://url.com/Smileys/sa/" + sreq.responseText) and a direct url like "http://url.com/Smileys/sa/goonpatriot.png") and neither seem to work.

The part of overlay.xul in particular is correct as far as I can tell, but posting it just in case:

code:

<toolbaritem flex="0" height="20">
	<image id="WOPR-ImgLeft" />
</toolbaritem>
<toolbaritem flex="0" align="center">
	<label id="WOPR-GetMessage" />
</toolbaritem>
<toolbaritem flex="0" height="20">
	<image id="WOPR-ImgRight" />
</toolbaritem>

Edit:

Never mind, fixed.
