如何从字符串中删除最后一个'[]'？

Question

I have some auto-generated text that includes substrings inside '[]'.

For example:

data[0]['x'][1]['y']

I want to get rid of the last sub-string.

Output:

data[0]['x'][1]

Any ideas?

Answer 1

var result = input.replace( /\[[^\]]*\]$/, '' )

会做的伎俩

Answer 2

If it's auto-generated it sounds like it will always have the same form. In that case, you could simply cut the string at the last occurrence of "["

var str = "data[0]['x'][1]['y']";
str = str.substring(0, str.lastIndexOf("["));
