My function is :

function collect_que_ids(e) {

  var val = e.val();

  var data_lo = e.attr('data-lo');

  new_hash = {};

  new_hash[val] = data_lo;

  if(e.is(':checked')){

    if(checked_box_hash.includes(new_hash)){

      checked_box_hash;

    }else{

      checked_box_hash.push(new_hash);

    }

  }

  else{

    new_hash_key = Object.keys(new_hash)[0]

    new_hash_value = new_hash[new_hash_key]

    $.each(checked_box_hash, function(key, value){

      if (typeof Object.keys(value) !== 'nil') {

        current_key = Object.keys(value)

        if (current_key[0] == new_hash_key && value[current_key[0]] == new_hash_value) {

          checked_box_hash.splice(key, 1)

        }

      }

    })

  }

};
