iframe on the page bottom: avoid automatic scroll of the page

Question

I have an iframe from the middle to bottom on a page. When I load the page it scrolls to the bottom. I tried to body onload window.scroll(0,0) but

Answer 1

Similar method but using classes.. I added a class to the iFrame's parent div of "iframe_display" with a style inside that of visibility: hidden. On page load I then used jQuery to remove the class

.iframe_display{visibility:hidden}

$(function(){
    $('#iframe_wrapper').removeClass('iframe_display');
});

This takes the focus away from the iFrame and stops the scrolling down to the iFrame on page load
