i have the following site, which makes a callback to a different domain.

      </td>

        <a href="" onclick="getParameters();"><img src="script/pic.png" alt="Get Data"/></a>
      </td>
     </tr>
    </table>
</body>
</html>

The stated script works fine, except for two major problems:

  1. it only works, when there is an alert(); in the script, which is not in the &.getJSON() function.
  2. after the last alert(); fires (“End of Script!”) the site is reloading (the browser says: http://code.jquery.com/ -> the jquery script) and after being finished. All data are gone.

Why? And how can I fix this?

    Try onclick="return getParameters();" and replace alert with return false; (or was it true?)

    Or replace a tag with span. Or remove it altogether and add onclick to the img.

    What happens now is that you initiate the async request and go on doing what would normally be done when clicking the link.
