Ajib, I am using jQuery, which makes an json object out of the json string you would get. This is very straightforward. Since you are using plain javascript this is not possible so easily.
Basically you get a string and need to turn it into a jsonobject. You could do it like that: http://www.json.org/js.html You probably need to make something like that: var myObject = JSON.parse(data); and then you can iterate over myObject like an array and create the html you need. I am afraid, you'll need to dig that out on your own now, but I guess you have a good direction ;-) Cheers Christian On Wed, Sep 28, 2011 at 6:08 PM, Anjib Mulepati <anji...@hotmail.com> wrote: > This is great I am able to get the String of all shows.
