Merge multiple serializeobject to one?

is it possible to merge multiple serializeobject to one serializeobject? I will be using it in a post. The serializeobjects are created via for loop.

var data = [];
for (var i = 0; i < riid_count; i++) {
  data[i] = $('input[type=checkbox][data-record='+i+']').serializeObject();
  data[i].id = $('input[name=id][data-record='+i+']').val();
  console.log(data[i]);
}

$.ajax({
  url : '<?php echo base_url() . 'index.php/unsubscribe/submit' ?>',
  data: data (hopefully access the merged objects),
  method: "POST",
  processData: true,
  dataType: 'json',
  error: function(xhr, status, thrown)
  {
  // i have stuff here
  },
  success: function(data)
  {
  // i have stuff here
  }
});

And here is an example of how the <form> element could look:

<form>
  <input type="checkbox" data-record="0" class="selection" name="somename"> 
</form>

Depending on the data I get from the database there can be up to 10 (or even more) checkboxes.

I still have no idea what your HTML might look like and what optimizations we could still carry out. But the following collects the input fields of those elements following a “checked” checkbox. Maybe it is of some help to you?

function collectData(){
  var data = [];
  for (var i = 0; i < 7; i++) {
    data[i] = $('input[type=checkbox][data-record='+i+']').serializeArray();
    if (data[i][0]) data[i][0].id = $('input[name=id][data-record='+i+']').val();
  // console.log(data[i]);
  }
  let da=data.filter(e=>e.length).map(e=>e[0]);
  console.log(da)
}
$('button').click(collectData);

input[type=text] {width:25px}
