Remove trailing '/' from rails string

Question

So i have this command at the moment, ITs breaking up a URL to get the ID from said URL

The URL has a forward slash on the end. Which is currently bringing in the ID like this

1111111/

I need to remove the forward slash on the end so its like 1111111

Heres what i have at the moment

  var apis = '<%= @event.slink.split('-')[-1] %>';

I have currently already tried putting .gsub on the end however that didnt work (I may have not done this right however)

Thanks

Answer 1

Try:

var apis = '<%= @event.slink.split('-')[-1].gsub(/\/$/, '') %>';

Answer 2

For your simple case use chop, which returns a new String with the last character removed.

"1111111/".chop #=> "1111111"

If you need extracts URIs from a string and to remove more end chars:

require 'uri'

CHARS = %{.,'?/!:;}
URI.extract(text, ['http']).collect { |u| CHARS.index(u[-1]) ? u.chop : u }
