Question

This simple regex is troubling me. Can you lend a hand?

How can I get Foo's Bar to return foos-bar in javascript?

var str = "Foo's Bar";
str.replace(/\s+/g, '-').replace('/[^a-zA-Z-]/g', '').toLowerCase();
return str;

The best I can do is foo's-bar, leaving the '.

Thanks.

Answer 1

Esailija is spot on – your regex is correct, but the second one is being interpreted as a string since it’s wrapped in quotes. With that fixed, your code works perfectly:

str.replace(/\s+/g, '-').replace(/[^a-zA-Z-]/g, '').toLowerCase();
