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://is.gd/api.php?longurl=%22http://nottingham.ac.uk/xerte>
"http://nottingham.ac.uk/xerte" which just displays the text on screen

 

Cheers

Ron
