Yii实现复选框批量操作实例代码

<?php $this->widget('zii.widgets.grid.CGridView', array( 'id'=>'user-grid', 'dataProvider'=>$model->search(),//Model里需要有个search()方法，$model是Controller中传递的Model对象// /'filter'=>$model, 'columns'=>array(    array(      'selectableRows' => 2,      'class' => 'CCheckBoxColumn',      'headerHtmlOptions' => array('width'=>'18px','align'=>'center'),      'checkBoxHtmlOptions' => array('name' => 'ids[]','align'=>'center'),    ),'homework_numberID','type','target','state','author_id',    array('name'=>'state','type'=>'raw','value'=>'($data->state =="not_read" ?"未读":"已审核")'),    // array('name'=>'passRecord','type'=>'date'),    array('name'=>'submit_time','type'=>'date'), array(   'class'=>'CButtonColumn', ), ),)); ?>

<select name="status" id="status">  <option value="1">通过</option>  <option value="0">不通过</option></select><button type="button" onclick="setStatus();" style="width:120px;">设置状态</button><script type="text/javascript">  function getData(){    var data=new Array();    $("input:checkbox[name='ids[]']").each(function (){      if($(this).attr("checked")){        data.push($(this).val());      }    });    return data;  }  function setStatus(){    var data = getData();    if(data.length < 1) {      alert('请至少选择一个项目。');      return ;    } //这里是传递的url post方法    $.post("index.php?r=user/status",{'ids[]':data,'status':$('#status').val()}, function (data) {      if (data=='ok') {        alert('设置状态成功！');      }else{        alert('设置状态失败，请重试！');      }      window.open('index.php?r=user/admin','mainFrame');;    });  }</script>

public function search()   {     // @todo Please modify the following code to remove attributes that should not be searched.     $criteria=new CDbCriteria;     //$criteria->with = array('author'); //添加了和 author 的渴求式加载     // $this->state = "not_passed";    $criteria->compare('state',$this->state);     //这里添加了一个 compare, username 是 User 表的字段,$this->name 是我们添加的属性,true 为模糊搜索     //$criteria->compare('username',$this->name,true);     return new CActiveDataProvider($this, array(      'criteria'=>$criteria,     ));
