首先是客户端的js代码：

function delrow(o){
if(confirm('确定要删除该图吗？')){
var div=$(o).parent().parent();
var id=div.attr('id');
$.ajax({
type:"POST",
data:{id:id},
url:"{:url('Goods/ajaxdelpic')}",
success:function(data){
if(data==1){
div.remove();
}else{
alert('删除失败！');
}
}
});
}
}

当请求发送到服务器端的时候我们是这样处理的：

// 异步删除商品相册图片public function ajaxdelpic($id){
$gphoto=db('goods_photo');
$gphotos=$gphoto->find($id);
$ogPhoto=IMG_UPLOADS.$gphotos['og_photo'];
$bigPhoto=IMG_UPLOADS.$gphotos['big_photo'];
$midPhoto=IMG_UPLOADS.$gphotos['mid_photo'];
$smPhoto=IMG_UPLOADS.$gphotos['sm_photo'];
@unlink($ogPhoto);
@unlink($bigPhoto);
@unlink($midPhoto);
@unlink($smPhoto);
$del=$gphoto->delete($id);
if($del){
echo 1;
}else{
echo 2;
}
}
