Question

使用以下代码我想要完成的是当'roleSelector'下拉列表更改时，它会向'admin / permissions / assign'url触发ajax请求，这会为所选角色设置一个状态。我需要它作为一个状态，所以我可以在CGridView中的CLinkColumn列中使用它。但是，当成功的javascript触发并且网格视图重新加载时，cgridview的内容不会更新，而摘要会更新（它显示应该在网格视图中的结果数）。

我不确定为什么，但这似乎是唯一一个我必须使用'ajaxUrl'属性才能使$ .fn.yiiGridView.update（）调用工作的CGridView。如果我省略url属性，它会返回一个错误，指出它无法找到我不记得必须在过去设置的url。

行动：

class AssignAction extends CAction {

    // Used in the url to determine if we are assigning or revoking permissions
    const FLAG_APPLY = 'apply';
    const FLAG_REVOKE = 'revoke';

    // Identifier to the user saved state of the role selected
    const STATE_ROLE = 'roleSelected';

    public function run($name='', $action='') {

        // Get the role the user selected
        if (isset($_POST['roleSelector'])) {
            $roleSelected = $_POST['roleSelector'];
            Yii::app()->user->setState(self::STATE_ROLE, $roleSelected);
            Yii::app()->end();
        }

        // Get all of the roles from the system
        $roleSelected = Yii::app()->user->getState(self::STATE_ROLE);
        $roles = AuthItem::model()->byTypes(array(CAuthItem::TYPE_ROLE))->findAll();
        $authItemProvider = new CActiveDataProvider('AuthItem', array(
            'criteria' => array(
                'condition' => (!$roleSelected) ? '1=0' : '',
            ),
            'pagination' => array(
                'pageSize' => 30,
            )
        ));

        $this->getController()->render('assign', array(
            'roles' => $roles,
            'roleSelected' => $roleSelected,
            'authItemProvider' => $authItemProvider,
        ));
    }
}

Answer 1

我忘了我把表标签放在那里，因为它最初是一个CListView。删除这些标签似乎解决了我的问题。

Yii CGridView没有使用JS调用更新
