Question

我对angularjs和javascript都很新，需要一些指导。我正在创建一个记录项目时间日志的应用程序。其中一列需要增量时间 - 启动日志和完成日志之间的时间差并消除间隔时间（例如，如果我在下午1点开始项目，在下午3点完成，但在增量时间之间有30分钟休息时间是2＆amp; 1/2小时）。到目前为止，这是我的代码，无论我尝试做什么，都会出现错误的时间或NaN。任何帮助将不胜感激！

控制器：

app.controller('MainController', ['$scope', function($scope) {
 $scope.title = 'Time Log';
 //$scope.promo = 'The most popular books this month.';

 $scope.logs = [];

 $scope.addLog = function() {

  $scope.logs.push({
   project: $scope.project,
   phase: $scope.phase,
   date: $scope.date,
   startTime: $scope.startTime,
   intTime: $scope.intTime,
   endTime: $scope.endTime,
   comments: $scope.comments
  });

  // Clear input fields after push
  $scope.project = "";
  $scope.phase = "";
  $scope.date = "";
  $scope.startTime = "";
  $scope.intTime = "";
  $scope.endTime = "";
  $scope.comments = "";
 };

 $scope.deltaTime = function(logs) {

  return $scope.startTime - $scope.endTime;

  ;
 }
}]);

Answer 1

试试这个

$scope.deltaTime = function(logs) {
      return new Date($scope.startTime) - new Date($scope.endTime);
     }
