i have web application want handle pinch zooming gesture in javascript rather allowing browser scale of ui. in ie11, it's understanding need specify touch-action css on element wish handle pointer events for. in application, i've disabled touch behavior except panning (touch-action: pan-x pan-y). i've wired pointerdown, pointerup, , pointermove events in javascript , i've added own calculations determine level of zoom perform based on distance between 2 active pointers (pinch gesture). in ie11 on desktop, works i'd expect; however, on mobile/metro version of ie (i've been testing on surface pro), can never seem detect more 1 pointer event @ given time. fires pointercancel on first captured event , fails fire second pointerdown. if disable touch gestures (touch-action: none), i'm able multi-touch pointer events in mobile browser well, no longer allows panning, undesirable. here's simple jsfiddle demonstrates issue: http://jsfiddle.net/wqgg0ly7...

why json stringify , parse not working object. works bad objects local variables? function task(description) { var _description = description; this.getdescription = function() { return _description; } } var task = new task('wash car'); console.log(task.getdescription()); var json = json.stringify(task); console.log(json.parse(json).getdescription()); json can't stringify functions (and it's not supposed able to). but technically when need stringify object should not need functions. can pass object within application. edit: if need object stored locally saving functions along not idea anyway. can store properties of object , create new instance when retrieve it.
