如何添加指向“目录树上方两级”的超链接？
我正在尝试编写我的主页按钮。有没有办法只爬回文件结构，而不是像我下面那样使用绝对路径。
我有一个文件index.html，位于 C:\Users\Randy\Documents\XML\
这是我的代码：
<a id="my-family" href="C:\Users\Randy\Documents\XML\index.html">Home</a>
这是我试图来自的地方：C:\Users\兰迪\文档\XML\项目\xml

要上两级，请使用“../../”和两级文件夹中的普通网址。
路径中的“../”用于向上一级。但是，它可以使用更多次，提升更多级别。
示例：
myfile.html 包含：
第二个“../”从 PICTURE_CONFIG 到 CONFIG 文件夹
第一个“../”从 CONFIG 转到 HOME 文件夹
“image.jpg”在 HOME 文件夹中搜索文件“image.jpg”
to go two level up use "../../" and your normal url from two level up folder.
"../" in the path is used to go one level up. But, it can be used for more times, to go more levels up.
an example:
myfile.html contains:
the second"../" goes from PICTURE_CONFIG to CONFIG folder
the first "../"goes from CONFIG to HOME folder
"image.jpg" searches in HOME folder for the file "image.jpg"
您可以使用
../index.html来引用父目录中的index.html。You can use
../index.htmlto refer toindex.htmlin the parent directory.在 Windows 操作系统上，正斜杠 (/) 不起作用，因此我切换到反斜杠 (\) 并修复了该问题。例如，尝试使用以下内容：
On Windows OS, the forward-slash (/) wasn't working, so I switched to back-slash (\) and that fixed it. For example, try using the following:
我不确定你到底在问什么，但在相对路径中，
../是“上一级”。因此，
../index.html会将您带到下一个目录的索引。希望有帮助。I'm not sure exactly what you're asking, but in relative paths,
../is 'up one level'.So,
../index.htmlwould take you to the index of the next directory up. Hope that helps.
希望此示例有所帮助:)

在 IIS10 中，下面是我的观察结果，两者都工作正常：
单个点将带您上面一个文件夹
img src="./images/picture.jpg"
双点将带您上面的两个文件夹
img src="../images/picture.jpg"
In IIS10 below is my observation and both works fine:
single Dot will take you one folder above
img src="./images/picture.jpg"
Double Dot will take you two folders above
img src="../images/picture.jpg"
