Why does this regex not work: '\([0-9a-zA-z]*\)';

Question

What I'd like to do remove the part of a string that is contained in brackets.

So for example be able to go from "Hello (World)" to "Hello".

I am using var input2 = '\([0-9a-zA-z]*\)'; as my expression statement, and using regular expressions to match this pattern.

Can someone tell me what I'm going wrong? I must be escaping the "(" and ")" incorrectly.

Answer 1

A-z should be A-Z.

If you want to be safe with those backslashes, escape the backslashes so you get \\( and \\) respectively, although I see nothing wrong with the backslashes.

Answer 2

Is this JavaScript? If so, you either need to escape the backslashes like @BoltClock said, or use a regex literal:

var input2 = /\([0-9a-zA-Z]*\)/;
