Do above. 做以上。 Plus, 加，

I guess you are using codeigniter? 我猜你在用codeigniter吗？

If yes, Make sure you have loaded the "url" helper. 如果是，请确保已加载“ url”帮助器。

Another step you can do is, view the source of the file, and check every link of your javascript. 您可以做的另一步是，查看文件的源，并检查JavaScript的每个链接。

Check your $config['base_url']. 检查您的$ config ['base_url']。 There should be a slash at the end. 最后应该有一个斜线。
