how to push the each loop variable value in to the array

Question

My problem is how do push each loop variable value in to the single array?(my code is not working)

$(document).on('click', '.overtime_check', function() {
   //temp = 0;

  $('#ot_send_table tbody tr').each(function(row, tr) {
    var test = [];
    var emp_no = $(tr).find('td:eq(0)').text();
    var ot_hours = $(tr).find('input').val();
    test.push(ot_hours);

    });
        $.ajax({
              url: 'ot_divide_action.php',
              type: 'POST',
              data: { action:'check_ot_count', test:test},
              //dataType:"json",
              success:function(data)
              {
              //swal({title: "No data entering?",text: "Not set the overtime hours !",type: "warning"});
              $('#display-output').html(data);
             }
          });
   //swal({title: "No data entering?",text: "Not set the overtime hours !",type: "warning"});

});

$time_arr =  [
'00:02:55',
'00:07:56',
'01:03:32',
'15:13:34',
'02:13:44',
'03:08:53',
'13:13:54'
 ];

how do i do it ?

update Code

First you iterate, then you send the ajax request. You don't put the ajax request inside the loop. — Federico klez Culloca

You need to make the variable global, declare it outside the each scope. — Marco

Your problem is that you define the var test = []; array inside the .each() callback. You need to define it before the iteration. Try this one:

$(document).on('click', '.overtime_check', function() {
    //temp = 0;

    var test = []; // Here, the array declaration should be outside the each()

    $('#ot_send_table tbody tr').each(function(row, tr) {
        var emp_no = $(tr).find('td:eq(0)').text();
        var ot_hours = $(tr).find('input').val();
        test.push(ot_hours);
    });

    $.ajax({
        url: 'ot_divide_action.php',
        type: 'POST',
        data: { action:'check_ot_count', test:test},
        //dataType:"json",
        success: function (data) {
            //swal({title: "No data entering?",text: "Not set the overtime hours !",type: "warning"});
            $('#display-output').html(data);
        }
    });
    //swal({title: "No data entering?",text: "Not set the overtime hours !",type: "warning"});
});
