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