what's wrong with this javascript regexp?

Question

Trying to find instances of "N/A" in markup and swap out with something else,

var $reg = new RegExp('[Nn]/[Aa]');

other variations were:

• /[Nn]/[Aa]/
• '^[Nn]/[Aa]'

Answer 1

I'd suggest:

stringToSearchIn.replace(/(N\/A)/gi,'words to replace with');

1. \\/ escapes the slash, as the / character delimits the regex string, and
2. the gi at the end:
   • g is for a global search, so it doesn't stop after the first match, and
   • i is case-insensitive (so it'll match n and N , a and A .
