in html5, there's a placeholder property for <input /> but some browsers(like IE6) don't support it, this project provide a fallback for them.
Usage: include placeholder_fixer.js on the bottom of your <body>
<!doctype html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<title>Demo</title>
</head>
<body>
<input type="text" placeholder="aaaaaa" />
<input type="text" placeholder="hahah" />
<input type="text" placeholder="fhhfsh" />
<input type="text" placeholder="bbbb" />
<script type="text/javascript" src="placeholder_fixer.js"></script>
</body>
</html>One important thing to notice is that you would have to use getValue() of the input element to get it's real value.
for example: var uname = document.getElementById("uname").getValue();
I can't find a way to simplify this step.
