typescript this cannot be referenced inside a module body -


i have module

module nganimaltracker {    export class traycontroller implements itraycontroller{         public starttracker() {         var monitor = new animalpositionmonitor(this);         this.animaltrackerservices.trackposition(monitor,  this.errorcallbackfn);     }    } } var animalpositionmonitor: = (() => {     var jsclass: = (traycontroller: itraycontroller) => {         **var monitor =  this;**          var me: igenxstreamhandler<ianimal> = new genxstreamhandler('animal');         me.process = animal => {             var ll = **monitor["traycontroller"].gridoptions.data.length**;         }     } } 

if don't have module works. need keep module, need monitor["traycontroller"] access element on process call won't lose scope. how do this?

based on new animalpositionmonitor(this); should refactor animalpositionmonitor class calling new.

going furhter code adding stuff me of type stream handler. pass in this use lambda, no need capture this in variable monitor.

class animalpositionmonitor{     constructor(traycontrller:itraycontroller){         var me: igenxstreamhandler<ianimal> = new genxstreamhandler('animal');         me.process = animal => {             var ll = this["traycontroller"].gridoptions.data.length**;         }        } } 

this quick video should understand this better : https://www.youtube.com/watch?v=tvocucbcupa
