webuploader上传成功后可以通过输入删除程序进行删除。

具体操作方法：

1、打开webuploader。

2、“点击选择图片”选择要删除的已上传图片。

3、输入程序：

//移除资源

$remove = isset($param['remove']) ? $param['remove'] : array(); // 获取移除数据

unset($param['remove']);

$tools = new \org\Tools;

$result = $tools->del_file('../public/uploads/images/', $remove);

$param['photo'] = isset($param['photo']) ? implode(',', $param['photo']) : ''; //获取插入数据

4、点击“确定”即可。

前台删除用的方法
uploader.removeFile(file);//从队列中移除
如果使用uploader..getFiles().length来判断上传的数量的话，可以清空队列

uploader.reset();//重置队列
