Wrap two adjacent elements in a containing div using jQuery

jQuery.Adjacent.Wrapping.htm

This is a useful trick if you want to wrap two sibling elements in a containing element, for example to fix stupid float bugs in IE7. I had a bit of a time figuring out how to select the right elements (wrapping is easy enough with one element, or one element's children), so I thought I'd share for the Greater Good.

From markup like this:

<div class='form-container'>
	...
	<div class='form-label'>Name (required)</div>
	<div class='form-field'><input type="text" name="you-name" value="" class="textbox" size="30" maxlength="200" /></div>

	<div class='form-label'>Email (required)</div>
	<div class='form-field'><input type="text" name="you-email" value="" class="textbox" size="30" maxlength="200" /></div>
	...
</div>

To this:

<div class='form-container'>
	...
	<div class='form-element-wrapper'>
		<div class='form-label'>Name (required)</div>
		<div class='form-field'><input type="text" name="you-name" value="" class="textbox" size="30" maxlength="200" /></div>
	</div>

	<div class='form-element-wrapper'>
		<div class='form-label'>Email (required)</div>
		<div class='form-field'><input type="text" name="you-email" value="" class="textbox" size="30" maxlength="200" /></div>
	</div>
	...
</div>

With a jQuery statement like this:

<script type='text/javascript'>
	$(".form-container .form-label").each(function(index) {
		$(this).next(".form-field").andSelf().wrapAll("<div class='form-element-wrapper' />")
	});
</script>

Pop the above tag in some IE7 conditional comments and enjoy.
