ajax删除

前端代码：点击删除时，需要在a标签或者button标签中带数据的id

ajax代码：

$('#a_del').click(function(){

var url = "{:U('Article/del')}";

var id = $(this).attr('data');

$.ajax({

    url:url,

    data:{

    id:id

    },

    type:'GET',

    dataType:'json',

    success:function(r){

        if(r.status == 200){

                alert(r.msg);

                location=location;

            }else{

            alert(r.msg);

            }

        }

    });

});

后端代码：

function del(){

    $id = I('get.id');

    // dump($id);die;

    $atticle = M('Article');

    if($atticle->delete($id)){

       $data['status'] = 200;

        $data['msg'] = '删除成功';

        $this->ajaxReturn($data);

    }else{

        $data['status'] = 400;

        $data['msg'] = '删除失败';

        $this->ajaxReturn($data);

    }

}
