How to add onload event to a div element
You can trigger some js automatically on an IMG element using onerror, and no src.
<img src onerror='alert()'>
No, you can't. The easiest way to make it work would be to put the function call directly after the element
Example:
...
<div id="somid">Some content</div>
<script type="text/javascript">
oQuickReply.swap('somid');
</script>
...
or - even better - just in front of </body>
:
...
<script type="text/javascript">
oQuickReply.swap('somid');
</script>
</body>
...so it doesn't block the following content from loading.
