Make iframe automatically adjust height according to the contents without using scrollbar? [duplicate]

Answer 1

function autoResize(id){
    var newheight;
    var newwidth;

    if(document.getElementById){
        newheight=document.getElementById(id).contentWindow.document.body.scrollHeight;
        newwidth=document.getElementById(id).contentWindow.document.body.scrollWidth;
    }

    document.getElementById(id).height=(newheight) + "px";
    document.getElementById(id).width=(newwidth) + "px"; 
}

add this to your iframe: onload="autoResize('youriframeid')"
