Regex javascript preceded by

Question

I'm working with regex in order to obtain a word from a string. I have a css class which has multiple classes like: "foo foo-bar foo-bar2 baz-foo" and I want to extract the word after every "foo-" string. In this case will be an array of two elements: "bar" and "bar2".

Does anyone know any way to do it using regex or, even with a javascript function?

I tried things like: /foo-\w+/g or /foo-\w+-\w+/g but I'm not an expert of regex.

Thank you in advance,

What are you trying to accomplish? If you're trying to pass data in the class name why not just using the data-* attributes? — Cfreak

You are actually after the word after foo-. Use foo-(\S+) and the group 1 will contain what you want.

it's better to use \S+

Yes it depends if OP has word characters that he only wants if not \S+ is fine for just matching the non-whitespace.

And what if I want only the word(s) after "foo-"? @AvinashRaj e.g if I have "foo-bar" and "foo-bar-baz" I want to obtain "bar" and "bar-baz". It is possible with a single regex or I have to split the result?
