Use drupal_to_js on the server and parseJson on the client to transfer serialized data in the server->client direction. I also like to send serialized JS to the server, but this requires external JSON libraries (both client and server side). -Robert Dan Robinson wrote:
I am trying to get some AJAX stuff to work -
javascript function -
function setMapContacts(uri, groupname) { HTTPGet(uri+"/"+groupname, addContactsToMap, "") ; }
this is the PHP function that gets called as a result of the above HTTPGet -
function getContacts($GroupName) { $contacts = getContactsInGroup($GroupName); print drupal_to_js($contacts); exit(); }
Here is the callback .js function I don't think I understand the correct way to format the callback - "contacts" has no value -
function addContactsToMap(httpresponse, xmlhttp, contacts) { if (xmlhttp.status != 200) { return alert('An HTTP error '+ xmlhttp.status +' occured.\n'+ httpresponse.uri); } ; map.clearOverlays(); alert(httpresponse); }
and I get a dump in httpresponse - the dump has the data i want in it - but I would much rather be dealing with a javascript array :). How do I get a javascript array? Is there a cast I have to do?
Thanks,
