arrays - 通过属性将数组传递给 AngularJS 指令

Question

目前，我在通过指令的属性将数组传递给指令时遇到问题。我可以将它作为字符串读取，但我需要它作为数组，所以这就是我想出的，但它不起作用。帮助任何人吗？提前致谢

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']" ... >

如果您从作用域访问此数组，即加载到 Controller 中，则只需传递变量的名称即可:

Binding array to directive variable in AngularJS

指令:

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

模板:

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