Question

在html中

<div ng-controller="homeCtrl as home">
<a class="list-group-item" ng-repeat="e in home.events | orderBy:'popularity'"> {{ e.name }}</a>
</div>

在控制器中

var vm = this;

vm.events = [{
            "name": "one",
            "popularity": 1
        }, {
            "name": "four",
            "popularity": 4
        }, {
            "name": "two",
            "popularity": 2
        }];

Answer 1

确保您在视图中使用 Controller As 语法

 <div ng-controller="ListCtrl as home">

<强>样本

var app = angular.module("app", []);

app.controller("ListCtrl", ["$scope",
  function($scope) {
    var vm = this;

    vm.events = [{
      "name": "one",
      "popularity": 1
    }, {
      "name": "four",
      "popularity": 4
    }, {
      "name": "two",
      "popularity": 2
    }];
  }

]);

Answer 2

您可能缺少controllerAs语法：

Answer 3

我的问题是我有

vm.events = {};

在调用函数之前

我将其更正为

vm.events = [];

并修复了它。

感谢您的回答。对不起，我的问题并没有我的所有代码：/

尽管数据是一个数组，但是ng-repeat上的命令仍无法正常工作
