我在 yii2 视图中遇到了困难的形式，其中一些字段显示或隐藏。它从用户字段选择中决定，在表单中选择选项。我用自定义 jquery 文件编写了这个前端逻辑。一切正常。但是当我提交表单时 - 隐藏的字段没有验证并且什么也没有发生。我怎么能杀死前端验证，当字段隐藏并打开它时，当字段可见时？

$form->field($model, 'youAttribute', ['enableClientValidation' => false])->textInput();
The ActiveFieldclass has a property enableClientValidation, you can simply set this property to falseif you want to disable clientValidation form some fields.
该ActiveField班有一个属性enableClientValidation，你可以简单地设置该属性false，如果你想禁用clientValidation形式的某些字段。

To disable client side validation. Begin your active form like this.
禁用客户端验证。像这样开始你的活动形式。
ActiveForm::begin(['enableClientValidation'=>false]);

You can set your active field using this code: (not active record, activefieldexactly)
您可以使用以下代码设置您的活动字段：（不是active record，activefield完全是）
$activeField = $form->field($model, 'someField');
$activeField->enableClientValidation=false;
$activeField ->enableAjaxValidation=false;

You can try setting default values for attributes that aren't set:
您可以尝试为未设置的属性设置默认值：
[
// set "username" and "email" as null if they are empty
[['username', 'email'], 'default'],
// set "level" to be 1 if it is empty
['level', 'default', 'value' => 1],
]
You can also use conditional client-side validationwith "whenClient"option when defining you validators:
您还可以在定义验证器时使用带有选项的条件客户端"whenClient"验证：
From the manual:
从手册：
If you also need to support client-side conditional validation, you should configure the whenClient property which takes a string representing a JavaScript function whose return value determines whether to apply the rule or not. For example,
[ ['state', 'required', 'when' => function ($model) { return $model->country == 'USA'; }, 'whenClient' => "function (attribute, value) { return $('#country').val() == 'USA'; }"], ]
如果您还需要支持客户端条件验证，则应配置 whenClient 属性，该属性采用表示 JavaScript 函数的字符串，其返回值决定是否应用规则。例如，
[ ['state', 'required', 'when' => function ($model) { return $model->country == 'USA'; }, 'whenClient' => "function (attribute, value) { return $('#country').val() == 'USA'; }"], ]

To remove a field from validation:
从验证中删除字段：
$('#yourFormID').yiiActiveForm('remove', 'yourinputID');
To add a field to validation list:
将字段添加到验证列表：
$('#yourFormID').yiiActiveForm('add', {
id: 'country',
name: 'yourinputID',
container: '.field-inputID', //or your cllass container
input: '#yourinputID',
error: '.help-block', //or your class error
validate: function (attribute, value, messages, deferred, $form) {
yii.validation.required(value, messages, {message: "Validation Message Here"});
}
});
And don't forget conditional validation in your model. More info
并且不要忘记模型中的条件验证。 更多信息

For your Form, use whenClient:
对于您的表单，请使用 whenClient：
['name', 'required', 'when' => {serverSide Condition),
'whenClient' => "ut_utils.isAttributeVisible",
],
['name', 'string', 'min' => 2, 'max' => 28],
['name', 'trim'],
And in ut_utils (JS):
在 ut_utils (JS) 中：
/**
* Useful for FE validation (whenClient) to validate only if visible (ie valid input)
*
* @param attribute Obj containing all sorts of info about attr including container name :-)
* @param value
*/
isAttributeVisible: function (attribute, value) {
return $(attribute.container).is(':visible');
},
You will need to add 'when' to validate serverside too you can add specific logic here or use a scenario to exclude attributes from being validated ...
您还需要添加“何时”来验证服务器端，您也可以在此处添加特定逻辑或使用场景从验证中排除属性...
