Insert HTML into iframe

I am creating a in browser HTML editor. I am using the syntax highlighter called Code Mirror which is very good.

My setup is an iframe that holds a view of the page which is being edited and a textarea which the plain text HTML sits which the user edits.

I am trying to insert the edited HTML from the textarea into the iframe which displays they rendered HTML.

Is this possible? I have tried the following:

HTML setup:

<iframe id="render">

</iframe>

<textarea id="code">
HTML WILL BE 

HERE
</textarea>
<input type="submit" id="edit_button" value="Edit" />

JQuery Setup:

$('#edit_button').click(function(){
    var code = editor.getCode(); // editor.getCode() is a codemirror function which gets the HTML from the text area
    var iframe = $('#render');
    iframe.html(code)
})

This does not seem to load the HTML into the iframe, is there a special method to insert HTML into a iframe or is this not possible?

Cheers

Eef

You can do it all on one line with jquery

$("iframe").contents().find('html').html("Your new HTML");

See working demo here http://jsfiddle.net/dWpvf/972/

Replace "iframe" with "#render" for your example. I left in "iframe" so that other users can reference the answer.

try 

iframe[0].documentElement.innerHTML = code;

Assuming that the url to the iframe is from the same domain as the webpage.

This problem bugged me too and finally found solution.

Its late but will add value to other visitors who might need proper fix.

    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN">
<html lang="en">
<head>
    <title>Iframe test</title>
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js">
    </script>
    <script type="text/javascript">
        $(function() {
            var $frame = $('<iframe style="width:200px; height:100px;">');
            $('body').html( $frame );
            setTimeout( function() {
                var doc = $frame[0].contentWindow.document;
                var $body = $('body',doc);
                $body.html('<h1>Test</h1>');
            }, 1 );
        });
    </script>
</head>
<body>
</body>
</html>
