Hi T.J,
Thanks for the response!
I got it to work, but I had to make some changes...
In 1.5, it used to return the actual response text from json, not the
header. The code is set to assign a variable to take that response
(see my example in the original post). Example:
// php file
$arrSomeStuff['name'] = "John Smith";
$arrSomeStuff['city'] = "Toronto";
echo json_encode( $arrSomeStuff );
// js file
onComplete: function(response, arrSomeStuff){
$('name_div').update(arrSomeStuff.name);
}
On 1.6, after some tinkering, the only way I could get it to work was
by making these changes:
// on the php file
header('Content-type: application/json');
echo json_encode( $arrSomeStuff );
// on the js file
onComplete: function(response){
var arrSiteVariable = response.responseJSON;
}
At this point, I guess my only question is, is there a way to get the
actual response on the second argument passed? (you know, without
massive changes...). Also, any particular reason the header was sent?
What is that useful for?
Thanks again!
