解决方法
_.wrap不是一个解决方案,如果你有20个路由,你必须把它们全部包装.
但是你可以用元编程来做到这一点
class Backbone.FlexRouter extends Backbone.Router
route: (route,name,handler) ->
super route,->
@trigger "route:before"
handler()
@trigger "route:after"
UPD：我相信JS应该是这样的(但我没有测试它)
var rp = Backbone.Router.prototype
rp.routeWithoutEvents = rp.route
rp.route = function(route,handler){
var that = this
this.routeWithoutEvents(route,function(){
that.trigger("route:before")
handler()
that.trigger("route:after")
})
}
