成功时使用 ajax 触发更改选择

问：

我的模式允许我更改所选分支的数据。使用 ajax，我可以通过我的 getter/get_location_info.php 获取数据，当我更改选择时，会填充以下选择。

我的城市选择是从我用 php 获取的列表中填充的，但其余的选择是通过我的 getter 用 ajax 填充的。当我选择要更新的分支时，我的模态城市选择是正确的，并且填充了县选择，它没有被选中，并且没有填充地区、宿舍。

“我要填充的脚本”选择：

<script>
    $(document).ready(function() {
        $('#edit_city').change(function() {
            var cityId = $(this).val();
            $.ajax({
                type: 'POST',
                url: 'functions/getters/get_location_info.php',
                data: {
                    city_id: cityId
                },
                success: function(counties) {
                    $('#edit_county').html(counties);
                    $('#edit_district').html('<option value="0">Semt Seçiniz</option>');
                }
            });
        });

        $('#edit_county').change(function() {
            var countyId = $(this).val();
            $.ajax({
                type: 'POST',
                url: 'functions/getters/get_location_info.php',
                data: {
                    county_id: countyId
                },
                success: function(districts) {
                    $('#edit_district').html(districts);
                    $('#edit_quarter').html('<option value="0">Köy Mahalle Seçiniz</option>');
                }
            });
        });

        $('#edit_district').change(function() {
            var districtId = $(this).val();
            $.ajax({
                type: 'POST',
                url: 'functions/getters/get_location_info.php',
                data: {
                    district_id: districtId
                },
                success: function(quarters) {
                    $('#edit_quarter').html(quarters);
                }
            });
        });
    });
</script>

我的脚本，用于获取分支数据并更新模态输入值：

<script>
    $('.btn-edit-branch').click(function() {
        var branchId = $(this).data('branch_id');
        var city_id, county_id, district_id, quarter_id;
        $.ajax({
            url: 'functions/getters/get_location_info.php',
            type: 'POST',
            data: {
                branch_id_edit: branchId
            },
            success: function(data) {
                var branchInfo = JSON.parse(data);
                city_id = branchInfo.ref_city;
                county_id = branchInfo.ref_county;
                district_id = branchInfo.ref_district;
                quarter_id = branchInfo.ref_quarter;
                // Set branch information in modal form
                $('#edit_branch_id').val(branchInfo.id);
                $('#edit_branch_name').val(branchInfo.branch_name);
                $('#edit_address').val(branchInfo.address);
                $('#edit_branch_mail').val(branchInfo.email);
                $('#edit_branch_phone').val(branchInfo.phone);
                $('#edit_city').val(city_id).trigger('change');
                $('#edit_county').val(county_id).trigger('change');
                $('#edit_district').val(district_id).trigger('change');
                $('#edit_quarter').val(quarter_id).trigger('change');
            },
            error: function() {
                alert('Veriler çekilirken bir hata oluştu');
            }
        });
    });
</script>
