I’m completely new to using jQuery. Why isn’t this working?

<iframe width="800" scrolling="no" id="prev" src="">your browser needs to be updated.
</iframe>
<script src="jquery.js"></script>
<script>
    //var c = 0;
    $(document).ready(function() {
        $('#prev').contents().html("<html><body><div> blah </div></body></html>");
    })
</script>

Also, I am planning on using this iFrame to present a preview of changes to an html file to a user. I am going to either empty the entire iFrame every time a change is made or, if I can figure out how to do so, change particular lines using jQuery. Is that the best way to go about this?

    If you want to update the iframe content using html then you should first find the body element inside the iframe and then append the required markup.

    $(document).ready(function() {
    $('#prev').contents().find('body').html('<div> blah </div>');
});
