使用angular js在所需格式中的两个日期时间之间的差异

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.7.9/angular.min.js"></script>

<div ng-app="myApp" ng-controller="myCtrl">
  <p>日期时间1: {{dateTime1}}</p>
  <p>日期时间2: {{dateTime2}}</p>
  <p>日期时间差异: {{dateDifference}}</p>
</div>

<script>
  var app = angular.module('myApp', []);
  app.controller('myCtrl', function($scope) {
    $scope.dateTime1 = new Date('2022-01-01T12:00:00');
    $scope.dateTime2 = new Date('2022-01-02T12:00:00');
    
    var diff = Math.abs($scope.dateTime2 - $scope.dateTime1);
    var minutes = Math.floor(diff / 1000 / 60);
    var hours = Math.floor(minutes / 60);
    var days = Math.floor(hours / 24);
    
    $scope.dateDifference = days + '天 ' + (hours % 24) + '小时 ' + (minutes % 60) + '分钟';
  });
</script>
