Answer 1

Normally you set and width and height for iframes. If the content inside is bigger, scrollbars have to suffice. The script below attempts to fix that by dynamically resizing the iframe to fit the content it loads.

you can use this function to set auto hight using jquery /javascript

<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<script>

     $(function(){

            var iFrames = $('iframe');

            function iResize() {

                for (var i = 0, j = iFrames.length; i < j; i++) {
                  iFrames[i].style.height = iFrames[i].contentWindow.document.body.offsetHeight + 'px';}
                }

                if ($.browser.safari || $.browser.opera) { 

                   iFrames.load(function(){
                       setTimeout(iResize, 0);
                   });

                   for (var i = 0, j = iFrames.length; i < j; i++) {
                        var iSource = iFrames[i].src;
                        iFrames[i].src = '';
                        iFrames[i].src = iSource;
                   }

                } else {
                   iFrames.load(function() { 
                       this.style.height = this.contentWindow.document.body.offsetHeight + 'px';
                   });
                }

            });
</script>

And your Iframe html like this

<iframe  src="http://www.google.com"  class="iframe" scrolling="no" frameborder="0"></iframe>
