Some untested Javascript:

	<script type="text/javascript" charset="utf-8">
		var formChanged = 0;
		var submitted = 0;
		window.onbeforeunload = function () {
			if (!submitted && formChanged) {
				return "You have unsaved changes.";

<form onsubmit="submitted = 1;">
	<input name=somefield onchange="formChanged = 1;">
