推荐答案

完全不包含路径信息，就像在链接中一样:

Include no path information at all, just like in a link:

window.location.replace("page2.aspx");

这是一个实时示例该示例在

http://jsbin.com/asupup/2   -- The "2" corresponds to your "page1.aspx"

...和

http://jsbin.com/asupup/3   -- The "3" corresponds to your "page2.aspx"

...因此2页面使用

window.location.replace("3");

...并且3页面使用

window.location.replace("2");

有关URL(尤其是相对URL)如何工作的更多信息，请参见 RFC3986 .但基本上:

For more about how URLs (and in particular relative URLs) work, see RFC3986. But basically:

• 如果相对URL 不是以.或/开头，它将替换最后一个段.所以:

• If a relative URL doesn't start with . or /, it replaces the last segment. So:

  http://foo.com/one/two/page.html
+ bar.html
= http://foo.com/one/two/bar.html

如果相对URL以../开头，它将替换最后一个段和:

If a relative URL starts with ../, it replaces the last segment and the one above it:

  http://foo.com/one/two/page.html
+ ../bar.html
= http://foo.com/one/bar.html

请注意，two子文件夹已被替换.多个../可用于上移多个级别:

Note that the two subfolder has been replaced. Multiple ../s can be used to move up multiple levels:

  http://foo.com/one/two/three/four/page.html
+ ../../bar.html
= http://foo.com/one/two/bar.html

如果相对URL以单个/开头，它将替换主机名(和端口(如果有))之后的所有内容.所以:

If a relative URL starts with a single /, it replaces everything after the hostname (and port, if any). So:

  http://foo.com/one/two/page.html
+ /bar.html
= http://foo.com/bar.html

  http://foo.com:8080/one/two/page.html
+ /bar.html
= http://foo.com:8080/bar.html

如果相对URL以//开头，它将替换协议中的所有内容，因此:

If a relative URL starts with //, it replaces everything following the protocol, so:

  http://ex.com/folder/page.html
+ //foo.com
= http://foo.com
