The following files should be updated (if you want to satisfy IE 8 users):

• \components\com_virtuemart\js\mootools\mootools-release-1.11.js  (update to 1.21)
• \components\com_virtuemart\js\mootools\mooPrompt.js (you have to revise it manually. Should change a lot of JS class definitions in accordance with mootools 1.21 syntax)
• \components\com_virtuemart\js\slimbox (update to slimbox for mootools 1.21)
• \components\com_virtuemart\themes\default\theme.js (you have to revise it manually. Should fix a bug on line 59, change to var timeoutID = setTimeout( ‘document.boxB.close()’, 3000 );)

Besides updating corresponding files, you can also disable Ajax function on the administration page. Or.. Wait until next stable release of VM). If you need the files above, just leave me a message, and I will pack them up for you.

The definition of my interface is:

Name: Rss2JSon
Interface: http://www.koumei.net/rss2json/
Method: GET
Parameter 1:  rss  – The URL of the rss content
Parameter 2: cb — The javascript callback function
Return: application/x-javascript
Example: http://www.koumei.net/rss2json/?rss=http://www.blogjava.net/max/rss&cb=<callback>  (A blog of my friend)

The callback function is very significant. Don’t forget to define a callback JS function on your script. The definition of the callback function should be similar as below ( parameter rss is an object, containing “title”, “link” and “description” and so forth<please go through RSS schema on item tag>.)

<script type=”text/javascript”> 

function myCallback(rss){
    var title = rss["title"];   // or rss.title
    var link = rss["link"];  // or rss.link
    var desc = rss["description"];  // or rss.description.
}

</script>

Now, you can embed the script to wherever you need.
<script type=”text/javascript” src=”http://www.koumei.net/rss2json/?rss=http://www.blogjava.net/max/rss&cb=myCallback”></script> 

Enjoy scripting.
