在ng-repeat中我们可以再嵌套一个ng-repeat
外层格式为ng-repeat="links in slides"
内层格式为ng-repeat="link in links track by $index"
注意要加上track by和索引值**$index**

<!DOCTYPE html>
<html ng-app="wsscat">
    <head>
        <meta charset="UTF-8">
        <title></title>
    </head>
    <script src="../js/angular.js"></script>

    <body ng-controller="indexCtrl">
        {{name}}
        <div ng-repeat="links in slides">
            <hr/>
            <div ng-repeat="link in links track by $index">
                {{link}}
            </div>
        </div>
    </body>
    <script>
        var app = angular.module('wsscat', []);
        app.controller('indexCtrl', function($scope) {
            $scope.name = "wsscat";
            $scope.slides = [
                [1, 1, 1],
                [4, 5, 6],
            ];
        })
    </script>
</html>
