Question

Getting my feet wet in Regular Expressions, and I’m having a difficult time getting this one to work.

I have a url as such:

/800-Flowers-inc-4124/18-roses-3123

Where 4124 is the business ID, and 3123 is the product ID.

The hard part for me is creating the capturing groups. Currently, my regex is as follows:

/(\d+)(?=/|$)/g

Unfortunately, that only selects the business ID, and doesn’t return the product ID.

Any help is greatly appreciated, and if you provide a regex, I would love if you could put a little explanation

thanks!

Answer 1

Your regex is fine, except since you’ve used the / as the regex delimiter you need to escape it in the expression:

/(\d+)(?=\/|$)/g

Or, you can just use a different delimiter (e.g. @):

@(\d+)(?=/|$)@g

Depending on the language you’re using it’ll probably return the results in some sort of array, or there could be a ‘findAll’-type method instead of just ‘find’.
