在第二次出现时在方括号之间提取字符串

Question

I have a string pattern like this:

She is [my] little [daughter].

How can I extract daughter from the above string?

Answer 1

You can use this regex:

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

And grab captured group #1

Answer 2

You need to use an anchored regex with capturing group.

^.*?\[[^\]]*\].*?\[([^\]]*)\]

Then get the string you want from group index 1.

DEMO

> console.log(/^.*?\[[^\]]*\].*?\[([^\]]*)\]/.exec('She is [my] little [daughter].')[1])
daughter

Answer 3

var st="She is [my] little [daughter].";
console.log(st.match(/.*\[(\w+)\]/)[1]);
