Question

So I have a $.post, that returns some json_encode($array);

$array is one dimensional, and it contains numbers: 2, 4, 6.

So now data is holding the json data, how can I loop through and make options to my #time selector? The value="" and display text should be the number from the array.

Answer 1

Something like that should work:

$.each(data, function(i, val) {
    $("<option />").text(val).val(val).appendTo("#time");
}​);​

UPDATE. Your data is not decoded from string format to JSON. Either add dataType property to $.post, or use data = JSON.parse(data) before making iteration.
