 var counter = 0;
var jsonObj;
var stringify, obj;

function myFunction(con) {
  counter = con + counter;
  $.ajax({
    url: 'http://localhost/driverapp/www/c11/week.php',
    type: 'POST',
    dataType: "json",
    data: {
      counter: counter
    },
    success: function(response) {
      jsonObj = JSON.stringify(response);
    }
  });
  alert(jsonObj);
}

    var json=[{"id":0,"date":"05-11-2018","total":0},{"id":1,"date":"06-11-2018","total":0},{"id":2,"date":"07-11-2018","total":0},{"id":3,"date":"08-11-2018","total":0},{"id":4,"date":"09-11-2018","total":0},{"id":5,"date":"10-11-2018","total":0},{"id":6,"date":"11-11-2018","total":0}];

for(var i = 0; i < json.length; i++) {
    var obj = json[i];
    console.log(obj.date);
}
