Question

我是AngularJs的新人。我刚开始学习依赖概念。但是当app.js和formapp.js之间的文件分开时，我遇到了问题。我无法访问users变量，因为它是分开的文件。我如何访问变量？。我希望你们能帮我解决这个问题。提前谢谢你。

的index.html

<!DOCTYPE html>
<html ng-app="training">
  <head>
    <link rel="stylesheet" type="text/css" href="../bootstrap.min.css" />
    <script type="text/javascript" src="../angular.min.js"></script>
    <script type="text/javascript" src="app.js"></script>
    <script type="text/javascript" src="formapp.js"></script>

        <link rel="stylesheet" href="../style.css" />
  </head>

  <body ng-controller="UserController as usersCtrl">

    <h3>User Information</h3>
    <div ng-repeat="user in usersCtrl.mUsers">
        <p><ul>
            <li>{{user.name}}</li>
            <li>{{user.age}}</li>
            <li>{{user.occupation}}</li>
        </ul></p>
    </div> 

    <form-Directive></form-Directive>

  </body>

</html>

app.js

(function(){

    var app = angular.module('training',['form']);


    app.controller('UserController',function(){

        this.mUsers = users;
    });

    var users = [{
        name:"michael",
        age:"27",
        occupation:"business"
    },{
        name:"john",
        age:"25",
        occupation:"police"
    }];

})();

formapp.js

(function(){
    var app = angular.module("form",[]);
        app.directive('formDirective', function(){
        return{
            restrict: 'E',
            templateUrl: 'user-form-directive.html',
            controller:function(){
                this.newUser = {};

                this.addUser = function(){
                    users.push(this.newUser);      //<-- users is not defined
                    this.newUser = {};
                };
            },
            controllerAs: 'formCtrl'
        };
    });
})();

您可以将 mUsers 作为属性传递给元素指令 - formDirective 。

<强>的index.html

///storage/0/emulated/...

<强> formapp.js

<form-Directive users='mUsers'></form-Directive>
