javascript - Extract characters in URL after certain character up to certain character -

i'm trying extract piece of url using regex (javascript) , having trouble excluding characters after piece. here's have far:

url: http://www.somesite.com/state-de

using url.match(/\/[^\/]+$/)[0] can extract state-de want.

however when url becomes http://www.somesite.com/state-de?page=r , same regex pulls including "?page=r" don't want. want extract state-de regardless of whats after (looks "?" follows it)

i'd recommend reading on regular expressions in general. want here make regular expression stop when hits ? in url.

using capturing groups select part of match want might useful here.

example:

url.match(/(\/[^\/?]+)(?:\?.*)?$/)[1]
