正则表达式查找方括号内的单个单词

Question

I'm stumped on the following regex problem.

I'm trying to find single words surrounded by square brackets without spaces. Like this:

[singleWord]

I don't want to find phrases, like this

[a series of words]

At the moment I'm using this regex:

/\[(.*?)\]/g

It's finding words and phrases. Can anyone suggest how to modify it so that it only finds words in square brackets without spaces?

Thanks!!

Answer 1

Try replacing .*? with \\S* in your regex. . will match any character including spaces, whereas \\S will match only non-space characters

/\[(\S*)\]/g

Answer 2

I'm trying to find single words surrounded by square brackets without spaces.

您可以使用此正则表达式：

/\[([^\s\]]*)\]/g

Answer 3

You current regex allows anything. You only want letters.

/\[([a-z])\]/gi
