I have read all the related posts and used them with no success. Obviously I’m not a javascript expert. I had tried with option, and selectedItem, but don’t know how to extract the select object to use it.
This is a fraction of my code, I hope you can help me.

I see you are already using JQuery
function in the code, and as far as Laravel
use that as well you can manage this with JQuery
. I did some changes so it should work as desired. Here is the example:
JavaScript
$("#add_row").on('click', function(e){
let row_number = $('#products_table tbody tr').length;
e.preventDefault();
$('#products_table').append('<tr id="product' + row_number + '"></tr>');
$('#product' + row_number).html($('#product' + (row_number - 1)).html());
});
$("#products_table").on('change', '#suajes_lista', function(e){
$("#test").val(this.value); //get current selected option value
alert('Row where the select was triggered has ID: ' + $(this).parent().parent().attr('id')); //get up on 1 level and get parent ID
});
JavaScript
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="card-body">
<input type="text" id="test" name="test" value="" class="form-control"/>
<button type="submit" id="add_row">Add new</button>
<table class="table" id="products_table">
<thead>
<tr>
<th>Descripción</th>
<th>Suaje</th>
</tr>
</thead>
<tbody>
<tr id="product0">
<td>
<input type="text" name="descripcion" class="form-control" value=""/>
</td>
<td>
<select id="suajes_lista" name="suajes_lista" class="form-control" style="width: 100px;">
<option value="">-- Select --</option>
<option value="1">1</option>
<option value="2">2</option>
</select>
</td>
</tr>
</tbody>
</table>
</div>
Hope it will help you understand the concept.
