With the following code:
framename.location.reload()
You could use it in a function or a link e.g.
<a href="javascript:framename.location.reload();">Reload frame</a>
...or if you wanted to refresh the page in the other frame when a link was clicked in the main frame....
<a href="pagewhatever.html" onclick="javascript:framename.location.reload();">Page Whatever</a>
...or in a function...
function myFunction(){
framename.location.reload();
}
Hope that helps
