angular.js ng-class-even ng-class-odd ng-cloak（没啥技术含量）

<!DOCTYPE html>
<html>
    <head>
        <meta charset="UTF-8">
        <title></title>
        <style type="text/css">
            .even{
                color: red;
            }
            .odd{
                color: blue;
            }
        </style>
    </head>
    <body ng-app="app">
        <ul ng-controller="people">
            <li ng-repeat="person in persons" ng-class-even="'even'" ng-class-odd="'odd'">
                {{person}}
            </li>
        </ul>
        <script src="js/angular.min.js" type="text/javascript" charset="utf-8"></script>
        <script type="text/javascript">
            var app = angular.module('app' , []);
            app.controller('people'  , ['$scope' , function($scope){
                $scope.persons = ['xudy' , 'lpf' , 'laogong' , 'laopo'];
            }]);
        </script>
    </body>
</html>

顺便说一下 ng-cloak就是在页面加载的时候，页面会显示{{}}这样的angular的表达式，为了在页面加载的时候不出现{{}}所以在指定的标签加上ng-cloak是非常必要的，但是angular.js不能放在最后面了，得放在head标签里面
