That is not a problem description.  Next time, show what you have tried, say 
what you expected to happen and why, and what happened instead.  And please 
post using your real name.

Given the code above, you are either calling this function the wrong way or 
the function does not make use of the “elm” argument.  Your code is wrong 
either way.

> invoiceArray = eval('(' + response.responseText + ')'); 

You might want to consider a wrapper that prefers 
JSON.parse(response.responseText) before the comparably unsafe eval().

  var invoice_listings = $('invoiceListings');
  invoice_listings.style.position = "relative"; 
  invoice_listings.style.left = "0";

Better yet, avoid $('invoiceListings') and associated libraries in favor of 
document.getElementById("invoiceListings") or something like that.

And finally, try replacing all of that with

  invoice_listings.style.display = "";

$('invoiceListings').style.left = "-5000px"; 
>                                                         
$('invoiceListings').style.visibility = "hidden"; 

Try replacing that with

  invoice_listings.style.display = "none"; 

NOTE: Elements where “display: none” are not subject to transition and 
animation effects, while nowaways the “visibility” property can be animated.  
But if you do not use those, using the “display” property is usually better.  

Consider viewports that are wider than 5000px, for example.  In fact, there 
should be no good reason to move the element at all in order to hide it, if 
you position it absolute and set its “visibility” property to “hidden”.
