I believe it goes like this
<script ...>
var tex
tex = (document.getElementById('bereich').value);
alert(tex);
</script>

its not possible to edit stuff in the <script> tags unless its inside a function, because greasemonkey is called on DOMContentLoaded and <script> tags run before that event
if its inside a function then from your greasemonkey script you just replace the function like

code:
unsafeWindow.functionName = function(){alert(":o");}

As long as it isn't used before Greasemonkey has had a chance to start.

FWIW, Opera's UserJS feature can modify the content of <script> tags...

quote:
User JavaScripts can use the 'BeforeScript' event to detect when a script on a page is about to be interpreted by the JavaScript engine. If needed, the contents of the script can then be rewritten, or prevented from being interpreted.

Can anyone attach that file (school blocks it),
and is anyone willing to give it a go using greasemonkey?
Thanks.
