RegEx - Get All Characters After Last Slash in URL

Question

I'm working with a Google API that returns IDs in the below format, which I've saved as a string. How can I write a Regular Expression in javascript to trim the string to only the characters after the last slash in the URL.

var id = 'http://www.google.com/m8/feeds/contacts/myemail%40gmail.com/base/nabb80191e23b7d9' 

Answer 1

Don't write a regex! This is trivial to do with string functions instead:

var final = id.substr(id.lastIndexOf('/') + 1); 

It's even easier if you know that the final part will always be 16 characters:

var final = id.substr(-16);
