its the same for both platforms (and web based programming)
两个平台（和基于 Web 的编程）都相同
. represents the directory you are in and .. represents the parent directory.
. 代表您所在的目录，.. 代表父目录。
in HTML if you have a file eg: http://example.com/blog/index.htmland you want to link to the image http://example.com/images/image.jpgyou would put it in as such:
在 HTML 中，如果您有一个文件，例如：http: //example.com/blog/index.html并且您想链接到图像http://example.com/images/image.jpg，您可以将其放入：
<img src="../images/image.jpg" />
As that tells the script to look in the PARENT directory and then images/image.jpg.
因为这告诉脚本查看 PARENT 目录，然后查看 images/image.jpg。
