删除 NodeJS 字符串中的括号

Question

I have a variable in Nodejs with square baskets. I need to remove the square brackets and extract the data out of it

let value = "[dfsdf][dsfsd][sdfs]MY VALUE";

I need MY VALUE from the value variable. the number of square brackets is not final. Sometimes it will be 1 or it can go up to 4

Answer 1

a simple solution without regex will be

value.split(']').slice(-1)[0]

or as per @Jeremy's comment.

.split("]").pop()

Answer 2

Another simple solution would be:

let value = "[dfsdf][dsfsd][sdfs]MY VALUE";
let myValue = value.substr(value.lastIndexOf(']')+1)

Answer 3

Use this regular expression to match square brackets:

/[\[\]]+/g

 let value = "[dfsdf][dsfsd][sdfs]MY VALUE"; console.log(value.replace(/[\[\]]+/g, ''))

Should you need to replace it with space use

value.replace(/[\[\]]+/g, ' ')

 let value = "[dfsdf][dsfsd][sdfs]MY VALUE"; console.log(value.replace(/[\[\]]+/g, ' '))
