I’m working on a small GreaseMonkey script where I would like to embed a jQuery plugin (Markitup) so that the script is fully self contained (images + js) except for jQuery which is served from google.

I found the site http://www.greywyvern.com/code/php/binary2base64 which says that you can embed javascript with the href if you base64 encode the script, much like serving images as basse64 from CSS.

<script type='text/javascript' href='data:text/javascript;base64,dmFyIHNjT2JqMSA9IG5ldyBzY3Jv...'></script>

So i tried that but couldn’t get it to work at all, using Firefox 3.0.5 on OS X.

I put together a small test page to isolate the problem but couldn’t get it to work at that page either.

<!DOCTYPE HTML> <html>    <head>       <title>Title</title>       <meta charset='utf-8'>    </head>    <body>       <script href='data:text/javascript;base64,YWxlcnQoJ2FzYWRhc2QnKTsK'></script>        <script>alert('a');</script>      </body> </html>

The base64 string (YWxlcnQoJ2FzYWRhc2QnKTsK) says alert('asadasd'); so I’m supposed to get two alerts but the only one I see is the second one where the alert is located as text inside the script tag.

Am I doing something wrong or why isn’t this working, any ideas?

  1. maybe just a thought but maybe the ‘href’ should be ‘src’ instead.
