TypeScript 中的 "=>" 真的很好用!!!

class funs
{　public $scope: IBarPadScope; constructor($scope: IBarPadScope) { this.$scope = $scope; }
    public createLoadPhoneOrders(startTime?: string): () => void {
        return () => {
            startTime = startTime || moment().format("YYYY-MM-DD 00:00:00");
            this.$scope.socket.emit(‘command‘,
                {
                    command: ‘query‘,
                    data: {
                        Node: this.$scope.sys.node,
                        CreatedTime: { ‘$gte‘: startTime }
                    },
                    document:‘PhoneOrders‘
                },
                (err, r: PhoneOrder[]) => {
                    this.$scope.$apply(() =>
                    {
                        this.$scope.allPhoneOrders = r;
                    });
            });
        };
    }
}
