Calculating hours difference between two dates in AngularJS
提问by mmmm
I've got template which looks like this:
我有一个看起来像这样的模板：
<tr ng-repeat="task in tasks" class="thumbnail">
<td ng-model="task.id">{[{ task.id }]}</td>
<td ng-model="task.time_start">{[{ task.time_start | date : 'MMM d, y HH:mm' }]}</td>
<td ng-model="task.time_stop">{[{ task.time_stop | date : 'MMM d, y HH:mm' }]}</td>
<td>[here i want the time difference]</td>
<td><button ng-click="edit(task)">Update</button></td>
</tr>
and I want to count hours difference between task.time_stopand task.time_start. Is there anyway to do this "live", in template?
我想计算task.time_stop和之间的小时差task.time_start。无论如何要"live"在模板中做到这一点？

Use the Moment library for this:
为此使用 Moment 库：
moment.utc(moment(task.time_stop.diff(moment(task.time_start))).format("mm")
You can wrap this call in a function:
您可以将此调用包装在一个函数中：
$scope.timediff = function(start, end){
return moment.utc(moment(end).diff(moment(start))).format("mm")
}
or even better create a factory for this... to make it reusable
甚至更好地为此创建一个工厂......使其可重复使用
PS: update your code to call the $scope.timediffto display the time difference:
PS：更新您的代码以调用$scope.timediff以显示时差：
<td>timediff(task.start,task.end )</td>
