I am trying to get a regular expression in Javascript where:
/something/:workspaceId/somethingelse/:userId/blah/:id
Is parsed so that I get an array with ['workspaceId', 'userId', 'id'].
Initial test:
p.match(/:.*?\/+/g )
This only matches the first two, workspaceId and userId.
This feels like a bit of a hack:
(p + '/').match(/:.*?\/+/g )
And it still returns :workspaceId rather than workspaceId.
Trying to fix it with whatI think the brackets should be for:
(p + '/').match(/:(.*)?\/+/g )
This last one really ought to work, but won't (since there are brackets, I expect the regexp only to return the match in the brackets).
At the moment, I am doing:
r = (p + '/').match(/:.*?\/+/g).map( function(i){return i.substr(1, i.length - 2 ) } );
But I would love to get something that:
1) Doesn't add that '/' at the end (although I could live with it)
2) It doesn't use the expensive map() method to do something the regexp should be doing in the first place
you could use a look ahead assertion regex for this, like so:
(?=:):(.*?)(?=\/|$)
working example:
Matches:
MATCH 1
1.
`workspaceId`
MATCH 2
1.
`userId`
MATCH 3
1.
`id`
Or better yet, you could simplify and just use:
:(\w+)
working example:
Matches:
MATCH 1
1.
`workspaceId`
MATCH 2
1.
`userId`
MATCH 3
1.
`id`
Edit:
Here is a working pure javascript example:
