I want JavaScript functions that will work just like escape() and unescape() that use an underscore instead of a percent.

My function below does not work, as the example demonstrates:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta charset="utf-8" />
<title>Demo</title>
</head>
<body>

<script type="text/javascript">
//<![CDATA[

var x = 'Hello_World "123%"';
alert(x);

x = escapeu(x);

x = unescapeu(x);
alert(x);

function escapeu(str) {
 return escape(str).replace(/%/g, '_' );
}

function unescapeu(str) {
 return unescape(str.replace(/_/g, '%' ));
}

//]]>
</script>
</body>
</html>

what about :
function escapeu(str) {
 return escape(str).replace(new RegExp(escape("%"),"g"), escape('_'));
}
