我只是从 http://docs.angularjs.org/api/ng.filter:orderBy 中获取了最简单的演示只需将年龄的值更改为具有不同的位数。它按预期停止工作。它的排序类似于“字符串”而不是“整数”值。我应该如何更改它以便它像整数值一样按年龄排序？

代码是:
function Ctrl($scope) {
$scope.friends =
[{name:'John', phone:'555-1212', age:'2352345'},
{name:'Mary', phone:'555-9876', age:'4235243'},
{name:'Mike', phone:'555-4321', age:'241'},
{name:'Adam', phone:'555-5678', age:'34325'},
{name:'Julie', phone:'555-8765', age:'1234'}]
$scope.predicate = '-age';
}

(<a href="" ng-click="predicate = '-name'; reverse=false">^</a>)</th>
<th><a href="" ng-click="predicate = 'phone'; reverse=!reverse">Phone Number</a></th>
<th><a href="" ng-click="predicate = 'age'; reverse=!reverse">Age</a></th>
</tr>
<tr ng-repeat="friend in friends | orderBy:predicate:reverse">
<td>{{friend.name}}</td>
<td>{{friend.phone}}</td>
<td>{{friend.age}}</td>
</tr>
</table>
</div>
</body>
</html>
最佳答案
您必须将年龄转换为数字类型才能使 orderBy 正常工作。
添加到您的 Controller 以将 String age 排序为 float:
angular.forEach($scope.friends, function (friend) {
friend.age = parseFloat(friend.age);
});
应该可以，
