What if we need one in JavaScript? Here's how to do just that!
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script language="javascript" type="text/javascript">
<!--
function htmlEncode(value) {
return $('<div/>').text(value).html();
}
function htmlDecode(value) {
return $('<div/>').html(value).text();
}
var s = "<b>hello's world</b>";
var encoded = htmlEncode(s);
var decoded = htmlDecode(encoded);
alert(encoded);
alert(decoded);
//-->
</script>
