Flabbergastion: Identical script works on one site, but not on another

[Travholt]

I'm a webmaster for a couple of sites. We have a deal with a business search provider, and we're putting a search box on our sites that's supposed to pop up a new window with search results from their site. Working example here:

http://www.ukeavisenledelse.no/

The box is the one in the top right named "Proff™ Firmasøk / Bransjesøk". It has been tested and found working in Safari, Firefox (Mac/Win) and IE 7.

But when the same code is duplicated – and I do mean duplicated, as in "copied and pasted without any modification whatsoever" – and pasted into the other site, it doesn't work, but rather just reloads the page. Non-working example here:

http://www.orapp.no/

(The box is in the same position on that site too, btw.)

I suspect it must have something to do with some other script which is on the latter site and not on the former, but I don't have enough experience with Javascript on the web to know how to start debugging – or even what tools to use.

So I guess my question is twofold:

1. Why does it work on one site but not another?

2. What kind of tool can I, a Mac guy, use to debug this myself another time?

I have Firebug (of course), but is not proving very useful in this case.

EDIT: First, here's the code:

<script language="javascript" type="text/javascript">
<!--
function testproffboksSendForm(f) {
  url = "http://search.eniro.no/partnersearch/search.c?service=PF_FIRMA&partnerID=Ukeavisen%20Ledelse&source=ukeavisenledelse.no&query="+escape(f.query.value);
  proffwindow = window.open(url);
  if (window.focus) { proffwindow.focus() }
  return(false);
}

function testproffboksSendMedEnter(f,e) {
  keycode = e.keyCode;
  if (keycode == 13) {
    testproffboksSendForm(f);
    return false;
  }
  else
    return true;
}

// -->
</script>

<div id="proffsokbox">
  <h2 class="proffsoktittel">Proff™ Firmasøk / Bransjesøk:</h2>

  <form method="get" action="javascript:void('');">
    <input id="query" name="query" class="sokfelt" size="10" value="" type="text" onkeypress="return testproffboksSendMedEnter(this.form,event)" ><input name="Submit" class="sokknapp" value="> Søk" type="submit"  onClick="testproffboksSendForm(this.form);" />
    <input type="hidden" name="service" value="PF_FIRMA" />
    <input type="hidden" name="partnerid" value="Okonomisk Rapport" />
    <input type="hidden" name="source" value="orapp.no" />
    </form>
  <ul class="profflinks">
      <li><a href="/nyttig/proff/roller" class="profflink1 profflinkfirst">Rollesøk</a></li>
        <li><a href="/nyttig/proff/nyheter" class="profflink1">Nyhetssøk</a></li>
        <li><a href="/nyttig/proff/kart" class="profflink1">Kartsøk</a></li>
        <li><a href="/nyttig/proff/kurs-konferanser" class="profflink2">Kurs-/konferanseplanlegger</a></li>
    </ul>
</div>

Second, I remembered that there's a builtin error console in Firefox, so I've used that and found that for orapp.no it says "newwindow has no properties". What I don't understand is why this is happening on one site but not the other.

Heh, what do they call it, "power of posting"? The increased chance that you find the solution to a problem just after posting about it on a forum.

Anyway, there is another script, "smsajax.js", which our CMS provider has installed, and in this script there is a function:

function open( ){
  document.location = document.location;
}

I guess it should be possbile to just rename that.
