I'm using ajax to send my data to controller and save it in database, before my code was working then I needed to sort my data when they append in blade after sorting them it stop working by %50.

Good to know

Here is my old code and solution of sorting my data (which caused this issue that i have now)

Logic

1. I select set
2. Set childs will append in blade (sorted by custom column)
3. I choose single or multiple options and hit save button
4. Data saves to database

More to know

My appended data (based on selected set) are include 2 types of data

1. Custom inputs (text field & text-area field) which i can manually fill and save (still working with no issue)
2. Dynamic select option which returns from database and i can select and save their id's (this is the issue dynamics)

Code

Script of appending data

<script defer>
$(document).ready(function() {
    $('select[name="selectset"]').on('change', function() {
        var id = $(this).val();
        if(id) {
            $.ajax({
                url: '{{ url('admin/selectset') }}/'+encodeURI(id),
                type: "GET",
                dataType: "json",
                success:function(result) {
                    $('div#dataaamsg').empty();
                    $('div#dataaamsg').append('Use <kbd>CTRL</kbd> or <kbd>SHIFT</kbd> button to select multiple options');
                    result.sort(function(a,b) {
                        return (a.position > b.position) ? 1 : ((b.position > a.position) ? -1 : 0);
                    });

                    $.each(result, function(key1, value1) {

                        var vvvid = value1.id;

                        if(value1['type'] == 'textfield'){
                            var my_row = $('<div class="row mt-20 ccin">');
                            $('div#dataaa').append(my_row);
                        }else if(value1['type'] == 'textareafield'){

script of saving data (issue part)

<script defer>
  $(document).ready(function() {
   $("body").on("click", ".savedynspecto", function(e){
      var form = $(this).closest('form');
      var id = form.find('input[name="product_id"]').val();
      // e.preventDefault();
      $.ajax({
        type: "post",
        url: '{{ url('admin/spacssendto') }}',
        data: {
          '_token': $('input[name=_token]').val(),
          'product_id': id,
          'subspecifications': $(this).closest('form').find('select.subspecifications').val()
        },
        success: function (data) {
          alert('Specifications added successfully.');
          console.log($(this));
        },
        error: function (data) {
          console.log(data);
        }
      });
    });
  });
</script>

Issue

1. When I try to save my dynamic values i cannot get id of selected option/options

   //returned data in network params _token g1GnKZvzXDztR1lqgDdjI5QOg67SfmmBhjm80fKu product_id 18 subspecifications

Ps1

I've tried to change val() to serialize() and I got

_token g1GnKZvzXDztR1lqgDdjI5QOg67SfmmBhjm80fKu
product_id 18
subspecifications subspecifications%5B%5D=20&subspecifications%5B%5D=21&subspecifications%5B%5D=23&subspecifications%5B%5D=32"

All I needed was 21,23,32 instead i got subspecifications%5B%5D= before each of them.

Ps2

I've tried to change $("body").on("click", ".savedynspecto", function(e){ that would not send any data to back-end (nothing prints in network not even error codes)

Any idea?
