How does ActiveForm submit asynchronously?

1. First configure the following attributes in the ActiveForm of the views layer

),           //此处为请求地址 Url用法查看手册
    'enableAjaxValidation' => true,
        'validationUrl' => Url::to(['post/validate']),     //数据异步校验
]);

2.配置好表单属性之后,在控制器中添加对应的方法

validateUrl对应的方法

//该方法是异步校验字段,输入框失去焦点之后自动会自动请求改地址
public function actionValidate(){
    $model = new PostModel();
    if (Yii::$app->request->isAjax && $model->load(Yii::$app->request->post())) {        
        Yii::$app->response->format = Response::FORMAT_JSON;        
        return ActiveForm::validate($model);
    }
}

action对应的方法

//该方法是数据保存方法
public function actionSave()
{
    $model = new PostCatModel();
    if ($model->load(Yii::$app->request->post())) {
        Yii::$app->response->format = Response::FORMAT_JSON;
        return ['status' => $model->save()];
    }        
}
Copy after login

In addition, you also need to write a submitted js

[code=php;toolbar:false">//此处点击按钮提交数据的jquery
$('.btn').click(function () {
$.ajax({
url: "/post/save.html",
type: "POST",
dataType: "json",
data: $('form').serialize(),
success: function(Data) {
if(Data.status)
alert('保存成功');
else
alert('保存失败')
},
error: function() {
alert('网络错误!');
}
});
return false;
});
Copy after login

Note: the corresponding in actionSave The namespace must be added, otherwise an error will be reported

For example, Response and ActiveForm

use yiiwebResponse;
use yiiootstrapActiveForm;[/code]
Copy after login

The above is the asynchronous submission method corresponding to ActiveForm
