How to run a function objects in array in prototype

Question

I have a Prototype class which has a function removeMarker.

var Location = Class.create({
    removeMarker: function(){
        // Some code here to remove a marker from a map
    }
});

I have an array of these:

var locations = [];

Is there an easy way to invoke removeMarker() on every location object in the array?

At the moment I am using:

locations.each(function(l,i) {
    l.removeMarker();
});

I am sure I have seen something using .map() or .invoke() but running

 locations.invoke(removeMarker);

doesn't seem to work. I know I am just doing something stupid, just need someone to point it out...

each and invoke are definitely not native JavaScript methods. I don't understand what your question has to do with prototypes and enumerable properties. — Felix Kling

@FelixKling: question title. "Prototype" offers/extends boths methods. — jAndy

@jAndy: Oh... I was too much thinking about, you know, prototype inheritance... nvm. Thanks! — Felix Kling

Try adding removeMarker between apostrophes.

So: locations.invoke('removeMarker');
