CGridView中实现批量删除 [ 技术分享 ]

1，CGridView中的columns添加

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[]'),
),

作用是添加多选框 2.js代码

<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('<?php echo CHtml::normalizeUrl(array('/admin/words/delall/'));?>',{'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.');
}
