Question

It is possible to make something like this?

$.ajax({
  url: "test.php",
  success: function(json, json1){ //Question here, can i have more than one?
    $m0 = [];
    $m0.push(parseFloat(json));
    alert($m0); //show 750

    $m1 = [];
    $m1.push(parseFloat(json1));
     alert($m1); // show 320
  }
});

and what is expected return in json?

this for example? [750, 320] or this [750] [320]?

Answer 1

I don’t think this is possible; JSON generally includes only a single top-level value. The standard approach would be to have test.php return a JSON array of two values:

[750, 320]

Your load function would then look like this:

$.ajax({
  url: "test.php",
  success: function(json){
    $m0 = [];
    $m0.push(parseFloat(json[0]));

    $m1 = [];
    $m1.push(parseFloat(json[1]));
  },
  // this will ask jQuery to parse the JSON for you;
  // otherwise, your success function will receive the
  // string "[750, 320]" as the argument
  dataType: 'json'
});
