Works!!!!!! Really helped a lot.
Thank you,
Thanks for this!! I've looked all over the net and this is the first javascript that actually works in all browsers!
Nice one.
I wonder why are using \s+ with 'g' option, instead of \s with 'g'. Curious?
I Use \s+ because Character (+)
"Repeats the previous item once or more. Greedy, so as many items as possible will be matched before trying permutations with less matches of the preceding item, up to the point where the preceding item is matched only once."
Nice work! Thanks for sharing this with the web development community (especially those of us not so well versed with Regular Expressions!)
