Cross browser Javascript regex

I am using the following code to convert a dynamic string into a valid class.

domain.replace('.','_','gi')

This works fine in all major browsers, but not in Internet Explorer and I'm wondering why. The gi flags are for global and case insensitive, but removing them means that the replace doesn't work in Firefox either.

Any ideas on how I change this to make it more friendly with more browers?

You need to do it like this:

domain.replace(/\./g, '_');

You'll need to use an actual regexp instead of a string:

domain.replace(/\./g, "_")

The third argument (flags) is non-standard.
