How to extract data from JSON string by using JQuery

@elvicmic Sorry for late reply. Again u'r above code worked without any problem. Thx a lot for that. But, the thing is that.. i'm doing all these for a google chrome extension. So, when i use above code inside my chrome extension it giving error like...

"XMLHttpRequest cannot load http://localhost/CI/index.php/welcome/chromeExtension. Origin chrome-extension://fddehjfinihjhhcnolbpbhckaagaefbp is not allowed by Access-Control-Allow-Origin.
localhost/CI/index.php/welcome/chromeExtensionFailed to load resource"

May b that why u'd suggested that "set headers correctly" . But, still using those headers in my controller function.. i've no luck(may be i'm not using the headers properly in side that controller function)..

My controller function is like this...

Code:

function chromeExtension()
{
    $this->load->model('home/welcome_page_model');
    $data = $this->welcome_page_model->latestThreadsForChromeExtension();

    $this->output->set_header('Last-Modified: '.gmdate('D, d M Y H:i:s', $last_update).' GMT');
    $this->output->set_header("Cache-Control: no-store, no-cache, must-revalidate");
    header('Content-type: application/json');

    echo json_encode($data);
}

For headers i'm using codeigniter output class : http://ellislab.com/codeigniter/user-gui...utput.html
