我的代码有些麻烦。
我正在尝试开发一个问卷应用程序，该应用程序将仅包含5个问题，每个问题有4种变体。
我在ng-switch中使用了ng-repeat，但是它不起作用。
附言这只是教育项目。
有index.html和app.js：
const testApp = angular.module('tespApp',[]);
testApp.controller('testAppCtrl', function ($scope) {
$scope.tasks = [
{id: '1', question1: 'Lorem ipsum dolor sit amet.', question2: 'Lorem ipsum dolor sit amet.', question3: 'Lorem ipsum dolor sit amet.', question4: 'Lorem ipsum dolor sit amet.'},
{id: '2', question1: 'Lorem ipsum dolor sit amet.', question2: 'Lorem ipsum dolor sit amet.', question3: 'Lorem ipsum dolor sit amet.', question4: 'Lorem ipsum dolor sit amet.'},
{id: '3', question1: 'Lorem ipsum dolor sit amet.', question2: 'Lorem ipsum dolor sit amet.', question3: 'Lorem ipsum dolor sit amet.', question4: 'Lorem ipsum dolor sit amet.'},
{id: '4', question1: 'Lorem ipsum dolor sit amet.', question2: 'Lorem ipsum dolor sit amet.', question3: 'Lorem ipsum dolor sit amet.', question4: 'Lorem ipsum dolor sit amet.'},
{id: '5', question1: 'Lorem ipsum dolor sit amet.', question2: 'Lorem ipsum dolor sit amet.', question3: 'Lorem ipsum dolor sit amet.', question4: 'Lorem ipsum dolor sit amet.'},
];
$scope.left = $scope.tasks.length;
$scope.taskNow = $scope.tasks[0].id;

你写了：
<div ng-switch-on="task.id">
但是应该是：
<div ng-switch on="task.id">
