Question

在一个ok项目中，它应该是这样的：

   <script type="text/javascript">
    jQuery(document).ready(function() {
                jQuery('#form-signup').yiiActiveForm({
                            "username": {
                                "validate": function(attribute, value, messages) {
                                    yii.validation.required(value, messages, {
                                        "message": "Username\u4e0d\u80fd\u4e3a\u7a7a\u3002"
                                    });
                                    yii.validation.string(value, messages, {
                                        "message": "Username\u5fc5\u987b\u662f\u4e00\u6761\u5b57\u7b26\u4e32\u3002",
                                        "min": 2,
                                        "tooShort": "Username\u5e94\u8be5\u5305\u542b\u81f3\u5c112\u4e2a\u5b57\u7b26\u3002",
                                        "max": 255,
                                        "tooLong": "Username\u53ea\u80fd\u5305\u542b\u81f3\u591a255\u4e2a\u5b57\u7b26\u3002",
                                        "skipOnEmpty": 1
                                    });
                                },
                                "id": "signupform-username",
                                "name": "username",
                                "validateOnChange": true,
                                "validateOnType": false,
                                "validationDelay": 200,
                                "container": ".field-signupform-username",
                                "input": "#signupform-username",
                                "error": ".help-block"
                            },
</script>

但是在我的项目中，当我输入无效的电子邮件或用户名时，没有提示或错误显示！当我检查yii生成的代码时，我看到yiiActiveForm的空args

  <script type="text/javascript">
    jQuery(document).ready(function() {
        jQuery('#form-signup').yiiActiveForm([], []);
    });
</script>

谁能告诉我为什么？供应商文件夹有什么问题吗？

这可能是因为您的模型类未设置为在正确的方案中，导致跳过验证。请查看有关此主题的文档：

http://www.yiiframework.com/doc-2.0/guide-structure-models.html#scenarios

如果您希望在当前视图上应用某些规则，则需要在创建模型实例时设置方案：

// scenario is set as a property
$model = new User;
$model->scenario = 'login';

// scenario is set through configuration
$model = new User(['scenario' => 'login']);

在您的模型中，用户上面的案例，您将拥有此功能：

namespace app\models;

use yii\db\ActiveRecord;

class User extends ActiveRecord
{
    public function scenarios()
    {
         return [
            'login' => ['username', 'password'],
            //more scenarios would follow here...
         ];
    }
}

yii.activeform.js生成无效的验证js脚本
