Delay load of iframe?

asked Oct 19, 2009 by sean

I know there are some tools and techniques for delaying the load of javascript, but I have an iframe that I would like to delay loading until after the rest of the page has finished downloading and rendering (the iframe is in a hidden that will not be revealed until someone clicks on a particular tab on the page. Is there a way to delay the load of an iframe? Any suggestions would be much appreciated. Thanks!

with jquery it is easy!

either enclose your code which loads the iframe within a $() or use $(document).ready(function(){}) these both are the same and would execute your code after the DOM is ready!


    $('iframe#iframe_id').attr('src', 'iframe_url');

Use Javascript in the onLoad event, or in the button click handler, to set the src attribute of the iframe.

Or my favorite use

setTimeout('your app', 6000)

That will make it wait x number of milliseconds to call any function....

You can also apply display:none to the iframe with CSS, then use jQuery's .show like this:

This works for me, but has problems if you change the code at all:

function loadIFrame() {
    window.frames['BodyFrame'].document.location.href = "iframe.html";
function delayedLoad() {
    window.setTimeout(loadIFrame2, 5000);


<iframe src="" onLoad="delayedLoad()"></iframe>

Load iFrame after page has loaded With JQuery and a little html and js

// Javascript
$(window).bind("load", function() {
  $('#dna_video').prepend('<iframe src="//" width="680" height="383" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>');
<!-- Append JQuery-->
<script src=""></script>

<!-- HTML -->
<div id="dna_video"></div>
