Question

我正在尝试学习角度并使这个示例脚本有效。

app.js：

＆＃13;

var myApp = angular.module("myApp", []);

(function (app) {
    app.controller("TodoListController", function () {
        var todoList = this;

        todoList.todos = [
            { text: "learn angular", done: true },
            { text: "build an angular app", done: false }];

        todoList.addTodo = function () {
            todoList.todos.push({ text: todoList.todoText, done: false });
            todoList.todoText = "";
        };

        todoList.remaining = function () {
            var count = 0;

            angular.forEach(todoList.todos, function (todo) {
                count += todo.done ? 0 : 1;
            });

            return count;
        };

        todoList.archive = function () {
            var oldTodos = todoList.todos;
            todoList.todos = [];

            angular.forEach(oldTodos, function (todo) {
                if (!todo.done) {
                    todoList.todos.push(todo);
                }
            });
        };
    });
})(myApp);

＆＃13;

Index.cshtml：

<!DOCTYPE html>
<html ng-app>
<head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title></title>

    <link href="content/Site.css" rel="stylesheet" type="text/css" />

    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.1/angular.min.js"></script>
    <script src="scripts/app.js"></script>
</head>
<body>
    <h2>Todo</h2>
    <div ng-controller="TodoListController as todoList">
        <span>{{todoList.remaining()}} of {{todoList.todos.length}} remaining</span>
        [ <a href="" ng-click="todoList.archive()">archive</a> ]

        <ul class="unstyled">
            <li ng-repeat="todo in todoList.todos">
                <label class="checkbox">
                    <input type="checkbox" ng-model="todo.done" />
                    <span class="done-{{todo.done}}">{{todo.text}}</span>
                </label>
            </li>
        </ul>

        <form ng-submit="todoList.addTodo()">
            <input type="text" ng-model="todoList.todoText" size="30" placeholder="add new todo here" />
            <input class="btn-primary" type="submit" value="add" />
        </form>
    </div>
</body>
</html>

不幸的是发生以下错误：＆＃34;控制器名称为＆＃39; TodoListController＆＃39;未注册。＆＃34;

非常感谢帮助。

Answer 1

您需要在html中注册“myApp”模块。在你的html的第二行，替换为此 <html ng-app="myApp">

Answer 2

你可以试试这个。

var myApp = angular.module("myApp", []);

(function () {
    "use strict";
    angular.module("myApp").controller("TodoListController", ["$scope", TodoListController]);

function TodoListController(){
 }
})();

<html ng-app="myApp"></html>

Answer 3

angular.module('MyApp',[])创建一个新模块，因为它包含依赖注入数组（作为第二个参数）。

尝试在代码中将angular.module('MyApp',[])更改为angular.module('MyApp')。

Angularjs控制器未注册
