NG-重复对数组的数组排序依据子数组索引 [英] ng-repeat on array of arrays, orderBy subarray index

问题描述

让我们说我有这个对象：

Let's say I have this object:

var rows = [
    [1, 2, 3, 4],
    [11, 222, 3333, 4444]
];

由于和这个模板：

Given that, and this template:

<tr ng-repeat="row in rows | orderBy ????">
    <td ng-repeat="cell in row">{{ cell }}</td>
</tr>

...我怎么能订购 NG-重复通过指数 1 给定的行元素）？

...how can I order an ng-repeat by the second "column" of each row (the value at index 1 of the given row element)?

我是纠正角度不支持这种情况下＆MDASH;而无需编写自定义排序函数？ （我只是原型，因此，使用 NG-INIT 来定义我的范围变量代替创建一个控制器。）

Am I correct that Angular does not support this case—without having to write a custom sort function? (I'm just prototyping, so using ng-init to define my scope variables instead of creating a controller.)

推荐答案

其实它的作用。您可以创建自定义的功能顺序。

Actually it does. You can create custom order by functions.

<div ng-repeat="row in rows | orderBy:secondIndex">
    {{row}}
</div>

//In controller
$scope.secondIndex = function(arr){
    return arr[1];
}
