So you want to load Page A, click on a link, stay on Page A, but execute a
function located in a script on Page B, without leaving A????
I've never done it, but I believe you call a javascript function which can
do it I think... maybe it's a POST form... sorry I can't be more help, but
I've never needed to do it.
If you can live with the page refreshing, then there's heaps of options.
