Yii中CGridView实现批量删除的方法

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

<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!");
 }
}
