<body ng-app="app"> <div ng-controller="myctl"> <ul> <li ng-repeat="item in arr"> {{item}} </li> </ul> </div> <script> angular.module("app", []).controller("myctl", function ($scope, $http) { $scope.arr = ["dd", "aa", "cc", "aa"]; }); </script> </body>
arr中有字符串"aa"重复，angular无法显示重复，想要显示可以加上：track by $index
<li ng-repeat="item in arr track by $index">
