Proper URL forming with Query String and Anchor Hashtag
提问by Dan
When both a query string and anchor tag (hash tag) are visible in a URL, what is the proper order for them to appear?
当查询字符串和锚标记（哈希标记）在 URL 中都可见时，它们出现的正确顺序是什么？
http://www.whatever.com?var=val#anchor
http://www.whatever.com?var=val#anchor
or
或者
http://www.whatever.com#anchor?var=val
http://www.whatever.com#anchor?var=val
Is there any documentation on this?
有没有这方面的文件？
update:The URLs are being handled by Wordpress / PHP

?var=var#hash
everything after #is client side.
之后的一切#都是客户端。
Also, look into url rewriting to get rid of ugly ?var=var
此外，研究 url 重写以摆脱丑陋 ?var=var

? should come before the #as noted in RFC 3986:
? 应该出现在 # 之前，如RFC 3986 中所述：
relative-ref = relative-part [ "?" query ] [ "#" fragment ]

回答by Teacher Michael
Note that when the URL has both anchor tags (#) and query strings (?), the browser may ignore the query string and navigate to the anchor tag without reloading the page.
请注意，当 URL 同时具有锚标记 (#) 和查询字符串 (?) 时，浏览器可能会忽略查询字符串并导航到锚标记，而无需重新加载页面。
It may be necessary to submit the page using a
可能需要使用
<form action='webpage.php?q=string#tag' method='GET or POST'>
<input type='text' id='q' name='q' value='string'>
<input type='submit' value='submit'>
</form>
rather than just a URL link
而不仅仅是一个 URL 链接
<a href='webpage.php?q=string#tag'>.

If intention of using #is to denote page fragmentthen- yes ?then #.
如果使用的意图#是表示页面fragment那么- 是?那么#。
If #is coming before ?and it is not to denote page fragment(this can happen when #is part of authority (username and password)) it has to be encoded or you are in trouble. Same applies to any other special characters (:,@,...) that could give different meaning to url.
如果#出现在之前?并且不是表示页面fragment（这可能发生在#权限的一部分（用户名和密码）），则必须对其进行编码，否则您将遇到麻烦。这同样适用于可能赋予 url 不同含义的任何其他特殊字符 ( :, @,...)。
