Laravel-admin 解决表单 select 联动时，编辑默认没选上

• /vendor/encore/laravel-admin/src/Form/Field下的Select.php文件

$script = <<<EOT
$(document).off('change', "{$this->getElementClassSelector()}");
$(document).on('change', "{$this->getElementClassSelector()}", function () {
    var target = $(this).closest('.fields-group').find(".$class");
    $.get("$sourceUrl",{q : this.value}, function (data) {
        target.find("option").remove();
        $(target).select2({
            placeholder: $placeholder,
            allowClear: $allowClear,
            data: $.map(data, function (d) {
                d.id = d.$idField;
                d.text = d.$textField;
                return d;
            })
        }).trigger('change');
    });
});

$('{$this->getElementClassSelector()}').trigger('change');

EOT;

添加

$('{$this->getElementClassSelector()}').trigger('change');
