Question

Im been trying to select all checkbox in my table when clicking the checkbox in my header but the problem is when I try to submit all selected list it include the checkbox header. What I want is only the tbody should return value

  $(':checkbox:checked')each(function(i){
        id[i]=$(this).val()
      })

$(':checkbox:checked')not('thead tr').each(function(i){
        id[i]=$(this).val()
   })

If you only want to select the checkboxes in the tbody element, include that in the selector:

$('tbody :checkbox:checked')

In addition you can simplify the logic to create the array of selected checkbox values by using map() instead of each(). Try this:

let id = $('tbody :checkbox:checked').map((i, el) => el.value).get();`

Here's the complete example without some other improvements to the logic:

jQuery($ => {
  $('#update_btn').click(function() {
    if (!confirm("Are you sure ?"))
      return;

    let csrf = $('input[name=csrfmiddlewaretoken]').val();
    let id = $('tbody :checkbox:checked').map((i, cb) => cb.value).get();

    $.ajax({
      url: "/update/",
      method: "POST",
      data: {
        id,
        'prov': "{{province}}",
        'muni': "{{municipal}}",
        csrfmiddlewaretoken: csrf
      },
      success: function(response) {
        url: "/dashboard/"
        /*
        Swal.fire({
          title: "Successfully saved!",
          text: "Mark As Paid",
          type: "success",
          confirmButtonClass: "btn btn-success",
          buttonsStyling: false
        })
        */
      }
    });
  })
});
