Hi Ron,

To load data into the HTML5 player you'll want to do an ajax call. In its simplest form:

$.ajax({
  url: "test.html",
  cache: false
}).done(function( html ) {
  // do something with html
});

If you try to do this cross server then you may run into the same origin policy though (http://en.wikipedia.org/wiki/Same_origin_policy)

The only way to do that is to do an ajax JSON with callback request (well tehnically its not ajax) but the page must return a valid JSON object wrapped in a function name, which may require creating a new file on a remote server...

Take a look at how the delicious, rss and youtuberss ones work, it'll be similar.

One think to think about though is that If you get it working in toolkits using proxy_rss then it won't work if exported to run in a scorm player...

Subject: [Xerte-dev] QRcode page for html5 version

Hi Fay
like Jonathan I thought I'd have a go with the html5 stuff and at converting one of the pages you haven't yet converted. As the QR code page was one I put together I thought I'd have a go at that. I used your textGraphics.html page as a starting point and have this working reasonably well as far as I can tell but have attached a copy here rather than committing it for now.

The bit I haven't got working and haven't even tried yet is how to grab the short url. In the flash version I used readfile() and in the case of xot use it together with rssproxy e.g.

myurl.readFile(_level0.site_url + 'rss_proxy.php?rss=' + "http://is.gd/api.php?longurl="+pastedurl);

my question is what's the equivalent of readFile for use with the xenith code? e.g. to read and display the result of something like http://is.gd/api.php?longurl="http://nottingham.ac.uk/xerte<http://is.gd/api.php?longurl=%22http://nottingham.ac.uk/xerte>" which just displays the text on screen

Cheers
Ron
