Question

I’m using this code

$.post("assets/scripts/chat/load_convos.php",{}, function(data) {
$.each(data, function(index, value) { 
  alert(value);
});

,and the return of the data is [57,49] but it just doesn’t do anything… If I replace the data just after the $.each( with [57,49] it works but not with the data in its place.

I’m not the best with Javascript so all help is much appreciated.

Answer 1

What do you mean with “the data is [57,49]” ?

My guess is, that you expect a (JSON)-object but you just receive a string. My second guess is that jQuery interpretates the result the wrong way and does not identify the return as JSON-String and hence, does not implicit JSON.parse it.

Check the content-types of the request. Try to call data = JSON.parse(data); manually before calling the each loop. Actually jQuery should be able to identiy that string as a JSON result itself, so I’m also wondering which jQuery version you use.

Another shot you might have is to call .getJSON() instead of .post() directly.
