Hi,

on one page have two iframes that displays two different web pages. Iframes hight is 900 px and width is set to 100%, scrolling is auto. Problem is that web pages are larger than size of iframe and they are not loading correctly. I want to have full size web page in iframe with scroll bars (horisontal and vertical if necessary, how to do that?

This Javascript function works in FF and IE:

// Sets iframe src
        function changeIframeSrc(id, url) {
            var el = document.getElementById(id);
            el.src = url;
}

Following code is used to resize iframe and called at iframe's onresize="reSize();":

/* Resizes iframe height to 100%.
        iFrame was not filling whole available area.
        So had to introduce this logic.*/
        function reSize() {
            try {
                var ifrm = document.getElementById('feedDetail');

                ifrm.style.height = '100%';
            }
            catch (e) {
                //window.status = 'Error: ' + e.number + '; ' + e.description;
            }
        }

Solution was to put iframe in div and then with div properties define size of an iframe and with iframe properties define page visibility properties (owerflow must be se to scroll). Anyway thanks for effort and help.

Cheers.
