javascript - AngularJS 按时间差排序

Question

我想启用按每个表字段排序。我有一列显示完成项目需要多少分钟，但按此字段排序无法正常工作。

<table>

   <th ><a href="" ng-click="sortBy='task.company_name'">Company</a></th>
   <th><a href="" ng-click="sortBy='timediff(task.time_start,task.time_stop)'">Time difference</a><th />

   <tr ng-repeat="task in tasks | orderBy:sortBy">
        <td >{[{ task.company_name }]}</td>
        <td >{[{ timediff(task.time_start,task.time_stop) }]}</td>
    </tr>

</table>

timediff函数:

$scope.timediff = function(start, end){
    var start = moment(start);
    var end = moment(end);
    var diff = end.diff(start,'minutes',true);
    return (diff/60).toPrecision(3);
};

简单修复，只需要将函数分配给参数即可

<tr>
    <th><a href="" ng-click="sortBy='company_name'">Company</a></th>
    <th><a href="" ng-click="sortBy='timediff'">Time difference</a></th>
</tr>
<tr ng-repeat="task in tasks | orderBy:sortBy">
    <td>{{ task.company_name }}</td>
    <td>{{ task.timediff = timediff(task.time_start,task.time_stop) }}</td>
</tr>

Here is an updated plunker 显示这一点并添加反向排序。
