I have the following JavaScript to rotate pages in a iframe tag every 5 seconds.

function setPage() {

    if (i == pages.length) {

        i = 0;

    }

    alert(pages[i]); //verify the right url is there

    var elmnt = document.getElementById('dashboard');

    elmnt.setAttribute('src', pages[i]);



    i++;

}

setInterval(setPage(), 5000);

The loop, interval, etc., is working. However, nothing changes for the src attribute of my iframe tag.

I tested with both IE8 and Chrome.

What am I doing wrong? How can I accomplish that (no jQuery...)
