Question

我的结d里有一个田地

        $this->crud->addField([
            'name'      => 'transaction_type',
            'label'     => 'Transaction Type',
            'type'      => 'select2',
            'entity'    => 'transactionType',
            'attribute' => 'name',
            'model'     => 'App\Models\TransactionType',
            'attributes' => [
                'required' => true,
            ],
        ]);

        $this->crud->addField([
            'name'      => 'developer_id',
            'label'     => 'Developer',
            'type'      => 'select2',
            'entity'    => 'developer',
            'attribute' => 'name',
            'model'     => 'App\Models\Developer',
        ]);

我想使developer_id所需的属性为true，因为默认情况下为false。我知道如何通过下面的代码将其设为虚假

$this->crud->modifyField('developer_id',['attributes' => [
      'required' => true,
]]);

现在的问题是，在developer_id中选择一个选项后，如何使'required' => true到transaction_type？到目前为止，我所要做的就是将'data_source' => url("admin/api/devrequirement")'放在transaction_type的addfield中。所以看起来像这样

$this->crud->addField([
            'name'      => 'transaction_type',
            'label'     => 'Transaction Type',
            'type'      => 'select2',
            'entity'    => 'transactionType',
            'attribute' => 'name',
            'data_source' => url("admin/api/devrequirement"), //i added it here
            'model'     => 'App\Models\TransactionType',
            'attributes' => [
                'required' => true,
            ],
        ]);

，然后将一条路线放入我的自定义路线中： Route::get('/api/devrequirement', 'SaleCrudController@setDevRequirement'); 该函数内部是：

public function setDevRequirement(Request $request)
    {
        $form = collect($request->input('form'))->pluck('value', 'name');
        $transaction_type = $form['transaction_type'];
        if($transaction_type == 3) //if transaction type is equal to a specific value then required attribute of developer_id should be true
        {
            $this->crud->modifyField('developer_id',['attributes' => [
                'required' => true,
            ]]);
        }
    }

但是它什么也没做。它没有在我的开发人员字段上添加红色星号，也没有要求验证。我在laravel背包以及如何使用其操作ajax方面遇到了困难。

没关系，我只是创建自定义字段并在其中放置一些js操作

背包换laravel如何在选择ajax时更改字段属性
