javascript - Regex for Array.replace(/ \]/g, ']')?

Question

I need to trim a space after '[' and before ']'.

To trim a space after '[', String.replace(/\[ /g, '['); works;

however, to trim a space before ']', String.replace(/ \]/g, ']'); seems not working.

What is the proper regex for that?

JavaScript.

你可以试试这个：

 str = str.replace(/\s+(\])|(\[)\s+/g, '$1$2');
