Link to current page without query string
提问by Alex S
I know there are a lot of tricks for doing links, for example <a href="?query=string">will link to the current page after appending the query string. Is there a way to link back to the current page, after removing the query string without just typing the file name?
我知道做链接有很多技巧，例如<a href="?query=string">在附加查询字符串后链接到当前页面。在删除查询字符串而不只是输入文件名后，有没有办法链接回当前页面？
Example, at the page foo.php?q=3, I want to link to foo.php. Is there a shortcut-type way to do this? The file will be renamed several times, so I don't want to type a bunch of links and then have to edit them later.
例如，在页面上foo.php?q=3，我想链接到foo.php. 有没有捷径类型的方法来做到这一点？该文件将被重命名几次，所以我不想输入一堆链接，然后必须在以后编辑它们。
Edit: Even though these are PHP files, I'm trying to avoid a server-side solution for this particular problem.
编辑：尽管这些是 PHP 文件，但我试图避免针对此特定问题使用服务器端解决方案。

href="?"
Not exactlywhat you are after - there's still a question mark at the end - but functionally equivalent.
不完全是你所追求的——最后仍然有一个问号——但在功能上是等效的。

I know it's almost 10 years later, but another way to do this client-side is to use Javascript, e.g.
我知道已经快 10 年了，但是在客户端执行此操作的另一种方法是使用 Javascript，例如
<a href="javascript:window.location.href=/^[^?]+/.exec(window.location.href)[0]">Anchor</a>
Not very pretty, but it does result in a clean URL when clicked.
不是很漂亮，但它确实会在点击时产生一个干净的 URL。

Are you wanting a client-side equivalent to $_SERVER['PHP_SELF']? Something that will always link to the file with no extra stuff after the extension?
你想要一个相当于 的客户端$_SERVER['PHP_SELF']吗？在扩展后总是链接到文件而没有额外内容的东西？
I'm not sure if this works in all browsers, but it works great in Firefox 3.5:
我不确定这是否适用于所有浏览器，但它适用于 Firefox 3.5：
<a href="">Foo</a>

You can link to the current page you're on with:
您可以链接到当前所在的页面：
<a href="#">blah</a>
