Select multiple elements in a regular expression

问题

I've got the URLs in the following style:

http://whatever.com/param1/val1/param2/val2

I want to match all key/value pairs. I tried this pattern:

/^http:\/\/whatever.com(?:\/([^\/]+)\/([^\/]+))*$/g

It only matches the last key/value pair.

Unfortunately, I cannot use code to get the pairs... How can I capture all pairs?

回答1:

Try making your match non-greedy by adding a ? after the *:

/^http:\/\/whatever\.com\/(?:([^\/]+)\/([^\/]+)\/?)*?$/g
