Javascript dynamically change onkeydown event?

[eboyjr14]

I have this UserScript for Grease monkey. but I can't get the onleydown event to fire in FIREFOX only. I've looked everywhere!

// ==UserScript==
// @name           iGoogle Suggest
// @namespace      Devin Samarin
// @description    This automatcally selects the top result for your query.
// @include        *google.com/ig*
// ==/UserScript==
function makeRequest() {
    GM_xmlhttpRequest({
        method: 'GET',
        url: 'http://suggestqueries.google.com/complete/search?output=firefox&client=firefox&qu='+encodeURI(document.getElementById('q').value),
        headers: {
            'User-agent': 'Mozilla/4.0 (compatible) Greasemonkey/0.3',
        },
        onload: function(responseDetails) {
 
            var response = responseDetails.responseText;
            document.getElementById('q').value = response.split('["')[2].split('"')[0];
        }
    });
}
var quer = document.getElementById('q');
quer.onkeydown = "alert('asa');";

onKeyDown = function() { ... };

onkeydown = function() { ... };

onkeydown = "...";

onKeyDown = "...";

onKeyDown = makeRequest;

onkeydown = makeRequest;

hi ...

add the onkeydown-eventhandling into a call from the onload-handler of the documents body ... during load the page is not fully rendered and the node is not available to be retrieved ... when you try it onload ... then the entire dom is loaded and document.getElementById finds your node and it will work then ;)

kind regards
