How to implement batch deletion of CGridView in Yii, yiicgridview

This article describes the method of implementing batch deletion of CGridView in Yii. Share it with everyone for your reference, the details are as follows:

1. Adding columns in CGridView

array(
 'selectableRows' => 2,
 'footer' => '<button type="button" onclick="GetCheckbox();" style="width:76px">批量删除</button>',
 'class' => 'CCheckBoxColumn',
 'headerHtmlOptions' => array('width'=>'33px'),
 'checkBoxHtmlOptions' => array('name' => 'selectdel[]'),
),

The function is to add a multi-select box

2.js code

<script type="text/javascript">
/*<![CDATA[*/
var GetCheckbox = function (){
 var data=new Array();
 $("input:checkbox[name='selectdel[]']").each(function (){
  if($(this).attr("checked")==true){
    data.push($(this).val());
  }
 });
 if(data.length > 0){
  $.post('<&#63;php echo CHtml::normalizeUrl(array('/admin/words/delall/'));&#63;>',{'selectdel[]':data}, function (data) {
   var ret = $.parseJSON(data);
   if (ret != null && ret.success != null && ret.success) {
    $.fn.yiiGridView.update('yw1');
   }
  });
 }else{
  alert("请选择要删除的关键字!");
 }
}
/*]]>*/
</script>

3.Action

public function actionDelall()
{
 if (Yii::app()->request->isPostRequest)
 {
  $criteria= new CDbCriteria;
  $criteria->addInCondition('id', $_POST['selectdel']);
  Words::model()->deleteAll($criteria);//Words换成你的模型
  if(isset(Yii::app()->request->isAjaxRequest)) {
   echo CJSON::encode(array('success' => true));
  } else {
   $this->redirect(isset($_POST['returnUrl']) ? $_POST['returnUrl'] : array('index'));
  }
 }
 else
  throw new CHttpException(400,'Invalid request. Please do not repeat this request again.');
}
