Include no path information at all, just like in a link:
完全不包含路径信息，就像在链接中一样：
window.location.replace("page2.aspx");
Here's a live exampleThe example switches between
这是一个活生生的例子该例子在
http://jsbin.com/asupup/2 -- The "2" corresponds to your "page1.aspx"
...and
...和
http://jsbin.com/asupup/3 -- The "3" corresponds to your "page2.aspx"
...and so the 2page uses
...所以2页面使用
window.location.replace("3");
...and the 3page uses
...并且3页面使用
window.location.replace("2");
For more about how URLs (and in particular relative URLs) work, see RFC3986. But basically:
有关 URL（尤其是相对 URL）如何工作的更多信息，请参阅RFC3986。但基本上：
If a relative URL doesn'tstart with
.or/, it replaces the last segment. So:http://foo.com/one/two/page.html + bar.html = http://foo.com/one/two/bar.htmlIf a relative URL starts with
../, it replaces the last segment andthe one above it:http://foo.com/one/two/page.html + ../bar.html = http://foo.com/one/bar.htmlNote that the
twosubfolder 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.htmlIf 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.htmlIf a relative URL starts with
//, it replaces everything following the protocol, so:http://ex.com/folder/page.html + //foo.com = http://foo.com(This is handy when loading resources and you want to avoid worrying about
httpvs.httpsand mixed-content warnings.)
如果相对 URL不以
.或开头/，它将替换最后一段。所以：http://foo.com/one/two/page.html + bar.html = http://foo.com/one/two/bar.html如果相对 URL 以 开头
../，它将替换最后一段和它上面的一段：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../s 可用于向上移动多个级别：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：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
//，它将替换遵循协议的所有内容，因此：http://ex.com/folder/page.html + //foo.com = http://foo.com（这在加载资源时很方便，并且您希望避免担心
httpvs.https和混合内容警告。）
