change ), in string with JavaScript

Question

I want to change string with JavaScript, I have string which includes ), and I want to have only comma, I try it :

fields = fields.replace(/),/g , '');

but this is results in an error.

Answer 1

You need to escape the parenthesis because the regex engine assume it as a close capture group and replace with , :

fields = fields.replace(/\),/g , ',');

Answer 2

Try this:

fields = fields.replace(/\),/g , ',');

You need to escape the ) with \) and replace '' with ','. When using replace it will replace the entire match from the first argument with the second argument. Since you include the , in your match you need to add it back in your replace...
