JavaScript - 使用正则表达式匹配非ascii符号

Question

I want to match all mentioned users in comment. Example:

 var comment = '@Agneš, @Petar, please take a look at this'; var mentionedUsers = comment.match(/@\\w+/g); console.log(mentionedUsers) 

I'm expecting ["@Agneš", "@Petar"] but getting ["@Agne", "@Petar"] . As you can see š symbol is not matched.

How can I match all letter symbols include non-ascii?

Answer 1

Until ES6 support for unicode in regex is implemented, you can work around it with somehting like:

/@[^\s,]+/g

where you just list stuff that can't be in usernames. Next year,

/@\w+/gu

A way to make sure you don't get halves of email adresses and other cases where the @ is in the middle of a word would be to match(/[^\\s,@]*@[^\\s,@]+(?=[\\s,]|$)/g) and then filter the results on whether they start with "@".

š不是单词字符，“w”代表单词字符。
