获取哈希符号后的请求部分
我的网站有 AJAX 支持的搜索，使用深度链接。当用户点击链接时……
http://example.com/articles#/?tags=Mac%20OS,review
标签“Mac OS”和“评论”应该已经在搜索表单中选择，并且与“Mac OS”和“评论”相关的文章应该出现在页面上。
我有以下情况，需要修复
- 用户点击链接 http://example.com /articles#/?tags=Mac%20OS
- 在初始页面渲染期间，所有文章都会在客户端获取
- ，哈希部分会被解析，并且仅通过 AJAX 请求与“Mac OS”相关的文章。
- 客户端接收“Mac OS”文章并替换在步骤 2 中获取的所有文章。还将“Mac OS”标签标记为在搜索表单上选择。
这里的问题是重复的文章渲染，这对用户来说看起来非常糟糕。他查看了所有文章，几秒钟后，它们将被替换为“Mac OS”文章。
我需要有以下场景：
- 用户点击链接 http://example.com/articles# /?tags=Mac%20OS
- 服务器解析哈希部分并返回“Mac OS”相关文章
- 客户端了解“Mac OS”文章已经存在并且不执行任何操作。它只是将“Mac OS”标签标记为已选择。
为此，我需要获取请求字符串的哈希部分：
/?tags=Mac%20OS
我无法在 ? 之后使用请求参数，因为我使用 AJAX 和深度链接。使用 ?-part，浏览器将被迫重新加载页面。我需要做任何事情而不重新加载页面。
我们将不胜感激您的帮助。
谢谢。
My web-site has AJAX-powered search, that uses deep-linking. When user follows a link …
http://example.com/articles#/?tags=Mac%20OS,review
… tags "Mac OS" and "review" should already been selected in a search form and articles, related to "Mac OS" and "review" should be presented on the page.
I have following scenario, that a need to fix
- User follows the link http://example.com/articles#/?tags=Mac%20OS
- During initial page rendering, all articles are fetched
- On the client side, hash-part is parsed and only "Mac OS"-related articles are requested via AJAX.
- Client receives "Mac OS"-articles and replaces all articles, fetched at step 2. Also it marks "Mac OS" tag as selected on a search-form.
The problem here - is duplicated articles rendering, that looks really bad for the user. He looks at all articles, and after couple of seconds, they will be replaced with "Mac OS"-articles.
I need to have following scenario:
- User follows the link http://example.com/articles#/?tags=Mac%20OS
- Server parses hash-part and returns "Mac OS"-related articles
- Client understands, that "Mac OS"-articles are already there and does nothing. It just marks "Mac OS" tag as selected.
To do this, i need to get hash-part of the request string:
/?tags=Mac%20OS
I cannot use request parameters after ?, because i use AJAX and deep-linking. With ?-part, browser will be forced to reload the page. I need to do anything without reloading the page.
You help will be greatly appreciated.
Thanks.

哈希值之后的 URL 部分不会发送到服务器，因此您无法在那里对其进行处理。您可以在创建 Ajax 请求的客户端代码中提取 URL 的部分并将其作为参数发送。
The part of a URL after the hash is not sent to the server, so you can't process it there. You can extract that part of the URL in the client-side code that creates your Ajax request and send it as a parameter.
@NickFitz 是正确的，但如果您必须发送
#哈希/磅符号之后的任何内容，则可以使用代表#的 URL 编码字符，即% 23。因此，
%23以及%23之后的任何内容都将发送到服务器。如果您使用现代网络服务器，它们会自动识别%23是#。在 Ruby on Rails 中，Rack 会为您完成此任务。@NickFitz is correct, but if you must send whatever comes after the
#hash/pound symbol, you can use the URL encoded characters that represent#which is%23.So
%23and whatever that comes after%23will be sent to the server. If you are using modern web server, they will automatically recognize that%23is#. In Ruby on Rails, Rack does this for you.
