javascript - SetTimeout inside emberjs model -

i have in emberjs application model doesn't has database data. have create model because want object pools requests server not binded controller or view.

something like: statuschecker

inside application.create this:

webapp = ember.application.create({   rootelement: '#content',   log_transitions: true,    ready: function() {     return webapp.status_helper = webapp.statushelper.create({       timer: 15     });   } }); 

this instantiate webapp.statushelper object must unique application. when call init on object start polling using default timer:

webapp.statushelper = ember.object.extend({   init: function(params) {     this.timer = this.get("timer");     this.timeoutid = null;     this.controller = null;     this.start();   },   start: function() {     this.execute();   },   stop: function() {     cleartimeout(this.timeoutid);   },   settimer: function(newtime) {     this.stop();     this.timer = newtime;     this.start();   },   execute: function() {     var $this = this;     this.stop();     $.get("/status").done(function(data) {       console.log(data);        if (data["status"] === 0) { // continue trying         $this.timeoutid = settimeout(function() {           $this.execute();         }, $this.timer * 1000);       } else if (data["status"] === 1) { // go given controller         $this.settimer(15);         $this.transitiontoroute('index'); // doesn't work       } else {         $this.settimer(15);         $this.transitiontoroute('problem'); // doesn't work       }     });   } }); 

the first problem cant change routes model using this: $this.transitiontoroute('problem');. there way model?

the second problem when controller need specify interval statushelper right after need stop timer , start interval, this:

webapp.indexroute = ember.route.extend   setupcontroller: (controller) ->     webapp.status_helper.settimer 15  webapp.problemroute = ember.route.extend   setupcontroller: (controller) ->     webapp.status_helper.settimer 1 

this happens because need check if problem solved every second, , index page transitions problem page whenever needs. after transition 2, , more, intervals working on same job.

how can stop , make 1 function work?

p.s.: if find need change model else can change it.

tl;dr

• how can change routes inside controller?
• how can have 1 function running interval?
• is there (better) way?

version of libraries:

you can't/shouldn't access router model. whenever find necessary it's clue maybe code writing should not model. in case webapp.statushelper should controller. like:

webapp.statuscontroller = ember.controller.extend({   //your code here }); 

then can rid of init() app.ready() hook , instead use setupcontroller hook of applicationroute configure , start timer. , of course since you're in controller able access router.

how can stop , make 1 function work?

so need start/stop timer when transitioning new routes. use route's activate, deactivate, , setupcontroller hooks turn timer on/off when routes change. way can ensure timer running when want to.

webapp.indexroute = ember.route.extend   activate: (controller) ->     this.controllerfor('status').settimer 15     this.controllerfor('status').start()    deactivate: (controller) ->     this.controllerfor('status').stop()  webapp.indexroute = ember.route.extend   activate: (controller) ->     this.controllerfor('status').settimer 1     this.controllerfor('status').start()    deactivate: (controller) ->     this.controllerfor('status').stop()
