angularjs - 如何检查值是否为数字

Question

我有这个功能:

 $scope.SearchTicketEvent = function (ticketPinOrEvent)
            {
                if (ticketPinOrEvent != undefined)
                {

                 if (ticketPinOrEvent.length == 10)
                    {

                     $scope.PinTicketSearch(ticketPinOrEvent);

                    }
                }


            }

如何检查 ticketPinOrEvent 是否为 number ？我试过 angular.isNumber(ticketPinOrEvent)但我什么也没得到？

Answer 1

如果你想使用 angular.isNumber

    if ( !isNaN(ticketPinOrEvent) && angular.isNumber(+ticketPinOrEvent)) {
    }
