coffeescript fat arrow access not parent 'this'

Question

This works great

    @nav.on 'click', ->
        _this.mover _this.nav.index $(@)

but I am wondering if I can use a fat arrow instead like this

    @nav.on 'click', =>
        @mover @nav.index $(????)

but what would I put in place of @ that will result in this instead of _this?

Answer 1

jQuery event handlers get an event object as an argument and that event object has target and currentTarget properties:

@nav.on 'click', (ev) =>
    @mover @nav.index $(ev.currentTarget)

You might want one of the other properties of ev depending on your specific circumstances.
