[Javascript] Multiple ajax calls onload

[Murphy, Matt]

All, 

I thought I had this ingenious idea, to make a slow-loading page load
faster, I'd break up the sections into divs, and then call a series of
ajax functions to populate those divs asynchronously. 

Problem is, only the last one called shows up. I can see in the firefox
error log that both document.getElementById('mydiv').innerHTML="myhtml"
calls ran, (the output of the php scripts called) but only one showed
up. 

Here's the js I'm using to call my ajax functions:

<script language="javascript">

function loadparts() {
ajaxme('script.php?var=var');
ajaxme('script.php?var=var2')
}
</script>

<script>
window.onload = loadparts();
</script>

Should this work? Is there a better way? 

Thanks,

Matt
