JavaScript String Variable Question

Here you go:

<html>
<head>
<script language="JavaScript" type="text/javascript">
function changeAction() {
document.players.action = document.players.frmAction.value;
}
</script>
</head>
<body>
<form name="players" method="get" action="http://www.yahoo.com" onsubmit="changeAction()">
Go to this page: <input type="text" name="frmAction">
<input type="submit" value="Go">
</form>
</body>
</html>

Just keep in mind that a lot of sites have disabled post action to their site, so you might have to always use the "get" method. Using the "get" method will work depending on the site. (some sites will not allow this either if you are passing an unrecognized parameter) All of this is due to security concerns.
