为＃标签解析文本并使用JavaScript代替链接

Question

如何用JavaScript代替Twitter风格#hashtags？

I.e. this is a #hashtag应该变成this is a <a href="tag/hashtag">#hashtag</a>。

对于PHP：Parse text for hashtags and replace with links using php

Answer 1

t = 'this is a #hashtag' 
t.replace(/#(\w+)/g, '<a href="tag/$1">#$1</a>') 

给人

this is a <a href="tag/hashtag">#hashtag</a>
