Question

PHP (processing.php):

$responce["x"] = 0;
$responce["y"] = [1, 3];
echo json_encode($responce);

javascript:

$.get("processing.php", function(data){
   alert("Data: " + data)
});

Output (alert):

Data: {"x":0,"y":["1","3"]}

I need to access the variable x, and the array y in javascript ?!!

Answer 1

Parse the JSON string with $.parseJSON().

Then, access data.x.

$.get("processing.php", function(data){
   data = $.parseJSON(data);
   var x = data.x;
});

Alternatively, you can set the dataType to json or use $.getJSON() which will automatically do it.
