meteor - When using a regex in iron router, how to access the match?

Question

Rather than having five different routes, I am trying to combined five different paths into a single function, but I still need to know which path it matched. So if I set up my route using a regex:

Router.route(/^/(accounts)|(contacts)|(forecasts)|(analytics)|(activities)/, function() {
    // which one did it match?
    console.log("matched "+this.params) //this returns an array of five params
}

how do I refer to the matched parameter inside the function?

this.params returns an array of five params with four of them undefined and the other matching, but which one is defined depends on what matched so this isn't very helpful.

Answer 1

I was able to use this.params after all by rewriting the regex as follows:

Router.route(/^/(accounts|contacts|forecasts|analytics|activities)/, function() {
    console.log('matched: '+this.params[0]);
}

Not sure if this is the best way to refer to a regex match tho.
