我试图用以下代码实现的是,当"roleSelector"下拉列表发生更改时,它会向"admin/permissions/assign"url发出ajax请求,从而为所选角色设置状态。我需要它作为一个状态,这样我就可以在CGridView的CLinkColumn列中使用它。然而,当成功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(它显示了应该在网格视图中的结果数量)。
我也不知道为什么,但这似乎是我唯一一个必须使用"ajaxUrl"属性才能使$.fn.yiiGridView.update()调用工作的CGridView。如果我省略了url属性,它会返回一个错误,说明它找不到我不记得过去必须设置的url。
行动:
class AssignAction extends CAction {
// Used in the url to determine if we are assigning or revoking permissions
const FLAG_APPLY = 'apply';
const FLAG_REVOKE = 'revoke';
// Identifier to the user saved state of the role selected
const STATE_ROLE = 'roleSelected';
public function run($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,
));
}
}
视图:
<div id="content-header">
<h1 class="p-mt10">Assign Permissions</h1>
<div class="p-fr p-pb10">
<?php
$roleList = CHtml::listData($roles, 'name', 'label');
echo CHtml::dropDownList('roleSelector', $roleSelected, $roleList, $htmlOptions=array(
'empty' => 'Select a Role',
'ajax' => array(
'type' => 'POST',
'url' => $this->createUrl('/admin/permissions/assign'),
'data' => array('roleSelector' => 'js: $(this).val()'),
'success' => 'js: function() { $.fn.yiiGridView.update("GridView-AuthItem") }',
),
));
?>
</div>
</div>
<div id="content-body">
<table>
<?php
$this->widget('zii.widgets.grid.CGridView', array(
'id' => 'GridView-AuthItem',
'dataProvider' => $authItemProvider,
'columns' => array(
'label:properCase',
'typeName:properCase',
'description',
'bizrule',
array(
'class' => 'CLinkColumn',
'label' => 'Assign',
'urlExpression' => 'array("/admin/permissions/assign",
"name" => $data->name,
"action" => (AuthItemChild::model()->byParentAndChild(Yii::app()->user->getState(AssignAction::STATE_ROLE), $data->name)->find()
? AssignAction::FLAG_REVOKE : AssignAction::FLAG_APPLY),
)',
'htmlOptions' => array(
'style' => 'text-align: center',
),
'linkHtmlOptions' => array(
'class' => 'button gray icon i_stm_edit',
),
),
),
));
?>
</table>
</div>
我忘了把表标记留在那里,因为它最初是一个CListView。删除这些标签似乎解决了我的问题。
