node.js regex extracting occurrences

Question

node.js regex extracting occurrences

I have this regex...

/user/([A-Za-z0-9]*)

Which is matched to this input string...

/user/me

Which brings this result in console...

['/user/me', 'me', index: 0, input: '/user/me']

Also see this example...

Regex: /user/([A-Za-z0-9]*)/([A-Za-z0-9]*)
Input: /user/me/you
Result: ['/user/me/you', 'me', 'you', index: 0, input: '/user/me/you']

First result just returns me but second returns me and you, is there a built-in function in node.js that will extract these occurrences or I would need to loop through this array with conditions?

javascript
regex
node.js

Answer 1

Just use Array.slice:

results=mystring.match(myregex).slice(1);

Answer 2

What version of Node are you using? The result of matching /user/me/you seems unreasonable. Anyway, I run code below on Node.js 0.8.4

> r = /\/user\/([A-Za-z0-9]*)/
  /\/user\/([A-Za-z0-9]*)/
> r.exec('/user/me')
  [ '/user/me',
    'me',
    index: 0,
    input: '/user/me' ]
> r.exec('/user/me/you')
  [ '/user/me',
    'me',
    index: 0,
    input: '/user/me/you' ]
