我想启用每个表字段的排序。我有一列显示了在项目上花了多少分钟,但按此字段排序并不能正常工作。
<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功能:
$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 显示此内容以及添加反向排序。

自定义函数有一种更简单的工作方式。我稍微编辑了数据集,以便在&#34; Company&#34;之间切换。和&#34;时差&#34;更清楚一点。
选项1 (DEMO):
如果属性名称没有更改,您可以执行以下操作:
$scope.timediff = function(task){
var start = moment(task.time_start);
var end = moment(task.time_stop);
var diff = end.diff(start,'minutes',true);
return (diff/60).toPrecision(3);
};
在你的html中,将函数分配给你的sortBy
变量:
<th ><a href="" ng-click="sortBy='company_name'">Company</a></th>
<th><a href="" ng-click="sortBy=timediff">Time difference</a></th>
<tr ng-repeat="task in tasks | orderBy:sortBy">
<td >{{ task.company_name }}</td>
<td >{{ timediff(task)}}</td>
</tr>
Angular会自动将当前项目传递到orderBy
中定义的函数。
选项2(更灵活)(DEMO):
如果要动态定义属性名称,可以返回另一个函数:
$scope.timediff = function(name1, name2){
return function(item) {
var start = moment(item[name1]);
var end = moment(item[name2]);
var diff = end.diff(start,'minutes',true);
return (diff/60).toPrecision(3);
}
};
并给它两个属性名称:
<th ><a href="" ng-click="sortBy='company_name'">Company</a></th>
<th><a href="" ng-click="sortBy=timediff('time_start', 'time_stop')">Time difference</a></th>
<tr ng-repeat="task in tasks | orderBy:sortBy">
<td >{{ task.company_name }}</td>
<td >{{ timediff('time_start', 'time_stop')(task)}}</td>
</tr>
