将数组via属性传递给AngularJS指令

Question

我通过该指令的属性将数组传递给指令时遇到问题.我可以把它读作一个字符串,但我需要它作为一个数组,所以这是我想出来但它不起作用.帮助任何人？事先说

使用Javascript ::

app.directive('post', function($parse){
    return {
        restrict: "E",
        scope:{
            title: "@",
            author: "@",
            content: "@",
            cover: "@",
            date: "@"
        },
        templateUrl: 'components/postComponent.html',
        link: function(scope, element, attrs){
            scope.tags = $parse(attrs.tags)
        }
    }
}

HTML ::

<post title="sample title" tags="['HTML5', 'AngularJS', 'Javascript']" ... >

如果从范围访问此数组,即加载到控制器中,则只需传递变量的名称:

将数组绑定到AngularJS中的指令变量

指示:

scope:{
        title: "@",
        author: "@",
        content: "@",
        cover: "@",
        date: "@",
        tags: "="
    },

模板:

<post title="sample title" tags="arrayName" ... >
