Hi! thank you.

But a question.

This part no found in IE.

var strclick = "changePage('" + url + "')";
nodes[n].setAttribute('onclick', strclick);

I try with:

nodes[n].onclick = function () { var frmPage = document.getElementById('frame1'); frmPage.src = strclick; };

But, no found again.

This problem is in IE.
