Question

I manage to incorporate an iframe resizing script by DynamicDrive and it works nicely.

http://www.dynamicdrive.com/dynamicindex17/iframessi2.htm

I set it up to load only on mouseover..

onmouseover="javascript:loadintoIframe('myframe', 'http://mysite.com/page.php)"

However, I need it to only load once instead of reloading on every hover.

I’ve tried this but I think I have to add something to javascript but not sure.

onclick="this.value = '';this.onclick=null;"

I guess if you want to keep the onmouseover handler delcared as an attribute, you could try:

onmouseover="javascript:if(loadintoIframe) {loadintoIframe('myframe', 'http://mysite.com/page.php); loadintoIframe=null;}"

The second time it gets called, it doesn’t do anything

Personally, I prefer using Unobtrusive JavaScript
