Change iFrame width and height on submit.

I have a form as such:
<form action="showPage.php" method="post" target="virtualDisplay">
Width : <input type="text" name="viewWidth" value="" /> x Height: <input type="text" name="viewHeight" value="" />
<button type="submit">try me.</button>
</form>

When the form is submitted, I want to change the height/width of an iframe located on the same page (via JavaScript):
<iframe src ="showPage.php" width="xxxx" height="xxxx" name="virtualDisplay">
  <p>Your browser does not support iframes.</p>
</iframe>


Thanks!

Depending on what your doing, it may be better to resize the iframe according to it's contents with an iframe onLoad event.

1) add id attributes to your iframe and two input text elements.
2) don't use the old type width and height attributes - but instead use the style.width and style.height like in this example
3) seriously consider using jquery - it makes every javascript programmers life SO much easier (haven't used it in this example)

<html>
<head>
    <script type="text/javascript">
        function $(elem) {
            return (document.getElementById(elem));
        }
        function resize(elem, viewWidth, viewHeight) {
            var newWidth = $(viewWidth).value;
            var newHeight = $(viewHeight).value;
            var e = $(elem);
            e.style.width = newWidth;
            e.style.height = newHeight;
        }
    </script>
</head>
<body>
<form action="#" method="post" target="virtualDisplay" onsubmit="return false;">
Width : <input id="viewWidth" type="text" name="viewWidth" value="1024" /> x 
Height: <input id="viewHeight" type="text" name="viewHeight" value="800" />
<button type="submit" onclick="resize( 'virtualDisplay' , 'viewWidth' , 'viewHeight' )">try me.</button>
</form>
<iframe src ="http://www.w3.org" id="virtualDisplay" name="virtualDisplay">
</iframe>
</body>
</html>
