Jquery setting .attr to an iframe scrolling=yes

Question

I have an iframe with "scrolling="no"" and a button that sets iframe attribute to scrolling="yes", when it's needed.

    $("#button3").click(function(){
    $( "#iframe_id" ).attr( "scrolling", "yes" );});    

But the scroll bar doesn't appear, when i press the button3, only after i refresh the iframe. How to force the srcoll bar appear instantly?

Answer 1

Now jquery sets .attr to scrolling="yes" and reloads the iframe!

$(document).ready(function () {
    $("#button3").click(function () {
        $("#iframe_id").attr("scrolling", "yes");
        $('#iframe_id').attr("src", $('#iframe_id').attr("src"));
    });
});

Trust me, there is no way you can do it with iframe. It will not work in Chrome or IE. I have played a lot with iFrame in past and such things never worked for me.

iFrame simply doesn't accept any changes, after it's loaded
