I am looking to format the TravelTimeHoursDiff and TravelTimeMinutesDiff in double digits. Currently, the time is displayed as 7:0 and I would like it to be displayed as 07:00.
if ($scope.DispatchStatus.ArrivalTime != undefined){
var today = $rootScope.getSysDate().split(" ");
var timeArrival = new Date(today[0] + ' ' + $scope.DispatchStatus.ArrivalTime);
var TravelTime = new Date(today[0] + ' ' + $scope.Route.TravelTime);
var timeArrivalHours = timeArrival.getHours();
var TravelTimeHoursDiff = timeArrivalHours - TravelTime.getHours() ;
var TravelTimeMinutesDiff = (timeArrival.getMinutes() - TravelTime.getMinutes());
if(TravelTimeHoursDiff < 0 || (TravelTimeHoursDiff <= 0 && TravelTimeMinutesDiff < 0) || (TravelTimeHoursDiff == 0 && TravelTimeMinutesDiff == 0)){
$scope.formvalidationbit = $scope.DispatchStatusAddForm[fieldName].$invalid = true;
angular.element('#' + fieldName).addClass('ng-invalid');
angular.element('#' + fieldName).removeClass('ng-valid');
$scope.DispatchStatusAddForm.$valid = false;
var errorbit = 1;
}else{
if (isNaN(TravelTimeHoursDiff)) {
TravelTimeHoursDiff = '--';
}
if (isNaN(TravelTimeMinutesDiff)) {
TravelTimeMinutesDiff = '--';
}
if(TravelTimeMinutesDiff <0){
TravelTimeMinutesDiff = TravelTimeMinutesDiff * (-1);
}
$scope.TravelTime = TravelTimeHoursDiff + ':' + TravelTimeMinutesDiff;
}
}
