我正在做一个AngularJS程序，我想在其中运行一个数组。这是我的程序：
<!DOCTYPE html>
<html>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"></script>
<body>
<div ng-app="myApp" ng-controller="myCtrl">
<p>Array: {{t}}</p>
<span style="margin:1px;background-color:cyan;" ng-repeat="x in names">
{{x}}
<span>
</div>
<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
// $scope.names = ["Emil", "Ellen", "Tobias", "Linus", "Poul", "Peter"];
$scope.names = ["Emil", "Emil", "Tobias", "Linus", "Poul", "Peter"];
$scope.t = angular.isArray($scope.names);
});
</script>
</body>
</html>
如果我使用$scope.names的更高版本，它会起作用。当我拿下较低的一个时，它会崩溃。根据isArray的说法，它们都是数组，那么为什么它不起作用呢？
非常困惑。

ngRepeat不支持在同一数组中有两个相等的值，您应该使用具有唯一标识符的对象，如下所示：
$scope.names = [{id: 0, name: 'Emil'}, {id: 1, name: 'Emil'}];
或者您可以使用track by，如下例所示

var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.names = ["Emil", "Emil", "Tobias", "Linus", "Poul", "Peter"];
});<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.7.5/angular.min.js"></script>
<div ng-app="myApp" ng-controller="myCtrl">
<p>Array: {{t}}</p>
<!-- $index: This special property tracks the collection items by their index -->
<span style="margin:1px;background-color:cyan;" ng-repeat="x in names track by $index">
{{x}}
</span>
</div>
