最近项目组需要将项目转到从ng1 转到 ng2。看了相关ng2关于指令的文档，可这是一头雾水，知道将$element 对应ng2 ElementRef,在细节还是不知所措，求指教！

Ng1 Directive

.directive("Touchmove", function () {
    return {
        controller: ["$scope", "$element", function ($scope, $element) {

            $element.bind("touchstart", onTouchStart);
            function onTouchStart(event) {
                event.preventDefault();
                $element.bind("touchmove", onTouchMove);
                $element.bind("touchend", onTouchEnd);
            }
            function onTouchMove(event) {
                var method = $element.attr("ng-touchmove");
                $scope.$event = event;
                $scope.$apply(method);
            }
            function onTouchEnd(event) {
                event.preventDefault();
                $element.unbind("touchmove", onTouchMove);
                $element.unbind("touchend", onTouchEnd);
            }

        }]
    }
});

.directive("Touchend", function () {
    return {
        controller: ["$scope", "$element", function ($scope, $element) {

            $element.bind("touchend", onTouchEnd);
            function onTouchEnd(event) {
                var method = $element.attr("ng-touchend");
                $scope.$event = event;
                $scope.$apply(method);
            }

        }]
    }
})     

HTML

<p touchend="mRelease()" touchmove="mTouch($event)" ng-click="mTouch($event)" >
        <p ng-repeat="c in indexs" style="width:100%;height:{{hIndex}}px;">
            {{c}}
        </p>
</p>

Ng2 ??
