Forms yii2动态加载pjax表单

问题：我想用pjax样式更新GridView，但它重定向到表单创建页面

以下代码的作用：

• 使用GridView的索引页显示数据列表，并在模式窗口中打开表单以创建新记录。表单代码被动态地添加到模式中
• 当点击索引页面上的“创建国家”按钮时，它调用Country/Create来获取表单的HTML代码并将其插入模式，然后显示模式窗口
• 单击表单上的“创建”按钮时，它会将表单提交给国家/地区/创建。这将返回索引页面的HTML代码，我希望它更新GridView部分，但它没有

守则：

当前时间：


使用Html:：button代替Html:：a并简单覆盖模式的内容：

yii\bootstrap\Modal::begin(['id' => 'modal']);
echo '<div id="modal-content"></div>';
yii\bootstrap\Modal::end();

echo Html::button('Create Country', [
    'onClick' => 'createCountry("' . Url::to([create]) . '")',
    'class' => 'btn btn-primary'
]);

$script = <<< JS
function createCountry(url) {
    $('#modal').modal('show').find('#modal-content').load(url);
}
JS

$this->registerJs($script, View::POS_END);

yii\bootstrap\Modal:：begin（['id'=>'Modal']）；
回声'；
yii\bootstrap\Modal:：end（）；
echo Html:：按钮（'创建国家'[
'onClick'=>'createCountry（'.Url:：to（[create]）。''，
“类”=>“btn btn主”
]);
$script=
