Cookies Store Bug

Question

我正在尝试放入我的内容，但无法显示。当我刷新时会显示不同的东西...有人能帮我解决这个问题吗？

<script src="./angular/angular.js"></script>
<script src="./angular/angular-cookies.js"></script>
<script>
    angular.module('cookieStoreExample', ['ngCookies'])
    .controller('ExampleController',['$scope', '$cookieStore', function($scope, $cookieStore){

        var exprs = $scope.exprs = [$cookieStore.get('myExprs',$scope.exprs)];

        $scope.addExp = function(exprs) {
            exprs.push(exprs);
        };


        $scope.removeExp = function(index) {
            exprs.splice(index, 1);
        };


        $cookieStore.put('myExprs',$scope.exprs);   
        var favoriteCookie = $cookieStore.get('myExprs',$scope.exprs);

    }])

</script>

Answer 1

这个例子似乎有几个问题：

• $cookieStore.get()已经返回了一个数组，不需要[]的。addExp()的
• 参数是exprs，因此需要调用exprs

来保持更改。

更新代码：

<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular-cookies.js"></script>
<script>
    angular.module('cookieStoreExample', ['ngCookies'])
    .controller('ExampleController', ['$scope', '$cookieStore', function ($scope, $cookieStore) {

        var exprs = $scope.exprs = $cookieStore.get('myExprs');
        if (!angular.isArray(exprs)) {
            exprs = [];
        }

        $scope.addExp = function (expr) {
            exprs.push(expr);
            $cookieStore.put('myExprs', exprs);
        };


        $scope.removeExp = function (index) {
            exprs.splice(index, 1);
            $cookieStore.put('myExprs', exprs);
        };


        $scope.favoriteCookie = $cookieStore.get('myExprs');

    }])

</script>
