Select Onchange with ajax

问题

i have problem with change by ajax. this is my code :

$(document).ready(function() {
  addBarang();
});

function addBarang() {
  var new_barang = $(".hidden_input").find(".barang_in").clone().addClass("barang_in_clone");
  $(".target_clone:last").append(new_barang);
  $(".barang_in_clone:last").find("input[name=show]").val('');
  //        $(".barang_in_clone:has(select)").addClass("select2");
}

$('body').on('click', '.btn_kurangi_barang', function() {
  $(this).closest('.barang_in_clone').remove();
});

 //Tampilkan model ketika memilih kode hanca
    function showModel(el) {
        if (el === "") {
            $(el).siblings("input[name=model]").val("");
        } else {
            $.ajax({
                url: 'vendor_inout/vendor_inout_crud.php',
                type: 'POST',
                dataType: 'JSON',
                data: {id_vendor_detail: el, type: "get_model"}, //get model dan ukuran
                success: function (data) {
                    console.log(data);
                    $(el).siblings("input[name=model]").val(data.nama_model + " " + "(" + data.ukuran + ")");
                },
                error: function (e) {
                    //called when there is an error
                    console.log(e.message);
                }
            });
        }
    }

回答1:

el is the element not the value of the element

use el.value to get the selected value or $(el).val(); via jquery

  function showModel(el) {
        if (el.value === "") {
            $(el).siblings("input[name=model]").val("");
        } else {
            $.ajax({
                url: 'vendor_inout/vendor_inout_crud.php',
                type: 'POST',
                dataType: 'JSON',
                data: {id_vendor_detail: el.value, type: "get_model"}, //get model dan ukuran
                success: function (data) {
                    console.log(data);
                    $(el).closest('.barang_in').find("input[name='model']").val(data.nama_model + " " + "(" + data.ukuran + ")");//get the parent element and then find the input
                },
                error: function (e) {
                    //called when there is an error
                    console.log(e.message);
                }
            });
        }
    }
