I know there are a number of "Try It Yourself" JavaScript editors, such as W3School's Try It editor , JSBin , and JSFiddle .
I'm developing a graphical JavaScript library that I'd like to let people try out from my own site (one difference from other editors is that my output would be to a canvas, not an HTML frame). Not wanting to reinvent the wheel, are there established ways for creating a "Try It Yourself" capability that consider issues like DOM-based scripting vulnerabilities?

A simple design would be a start page with a form containing three textarea's and one iframe. The textarea's contain the html/css and javascript parts, and the iframe contains the result:
ReplyDelete<!--index.html-->
<html>
<form method="post" action="tryit-result.php" target="result">
<button>Try it</button>
<table>
<tr>
<td><textarea name="html"></textarea></td>
<td><textarea name="css"></textarea></td>
</tr>
<tr>
<td><textarea name="js"></textarea></td>
<td><iframe src="tryit-result.php" name="result"></iframe></td>
</tr>
</table>
</form>
</html>
The submit is then handled at the server by saving the html/css/scripts to file and then returning a page that references these files, something in the line of:
<!--tryit-result.php-->
<html>
<head>
<style type='text/css'>
<?php echo file_get_contents('css contents')?>
</style>
<script type='text/javascript'>
$(function() {
<?php echo file_get_contents('js contents')?>
});
</script>
</head>
<body>
<?php echo file_get_contents('html contents')?>
</body>
</html>
