Iframe dynamic Height and src url using jquery

Below jquery code will help you to  generate dynamic height without scroll bar in iframe and also you can change src url dynamically. 

$(document)

    .ready(

        function() {

                  var newurl = 'any_url';

            $('#iframe_id').attr('src', newurl);

            // For other good browsers.

            $('iframe')

            .load(

                function() {

                    this.style.height = 0;

                    this.style.height = this.contentWindow.document.body.scrollHeight

                    + 500 + 'px';

                // this.style.width =

                // this.contentWindow.document.body.offsetWidth

                // + 100 + 'px';

                });

        });

Hope this will help :)

Cheers
