我是angularJS,Node和Express的初学者,我正在使用angularJS,Node和Express编写一个非常简单的待办事项列表的教程的开头。 我使用的是Node.js v7.9.0,Express.js v4.15.2和AngularJS v1.6.1。 我正在使用nodemon来运行我的server.js。
我一直有3个错误,我不明白为什么:
SyntaxError: expected expression, got '<'[En savoir plus] app.js:1
SyntaxError: expected expression, got '<'[En savoir plus] route.js:1
Error: [$injector:modulerr] Failed to instantiate module myApp due to:
[$injector:nomod] Module 'myApp' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.

这是我的文件路径:
-todolist
--node_modules
--public
---views
----home.hmtl
---app.js
---index.html
---route.js
--package.json
--server.js
我的server.js文件:
var express = require('express');
var app = express();
var bodyparser= require('body-parser');
var method = require('method-override');
//application
app.get('*', function(req, res){
res.sendFile('/public/index.html', {root : __dirname});
});
app.listen(3000);
我的app.js:
angular.module('myApp', ['appRoutes']);
我的路线.js:
angular.module('appRoutes', ['ngRoute'])
.config(function($routeProvider){
$routeProvider
.when('/', {
templateUrl: '/views/home.html'
}
)
});
我的index.html:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.6.1/angular.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.6.1/angular-route.js"></script>
<script src="app.js"></script>
<script src="route.js"></script>
<title>Une To-Do Liste</title>
</head>
<body ng-app="myApp">
<h1>To-do List</h1>
<div ng-view></div>
</body>
</html>
home.html包含一个简单的测试,但无法显示:
<h1>Hello</h1>
目前网站只显示我的index.html字符串'待办事项列表'。 为什么我的app.js和route.js会出现2个语法错误?为什么我的'myApp'模块没有定义?

我的app.js:
angular.module('myApp', ['ngRoute']);
我的路线.js:
angular.module('myApp')
.config(function($routeProvider){
$routeProvider
.when('/', {
templateUrl: '/views/home.html'
}
)
});
//with test controller
angular.module('myApp')
.controller('TestCtrl',['$scope', function($scope){
$scope.it = 'works';
}]);
的index.html
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.6.1/angular.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.6.1/angular-route.js"></script>
<script src="app.js"></script>
<script src="route.js"></script>
<title>Une To-Do Liste</title>
</head>
<body ng-app="myApp">
<div ng-controller="TestCtrl">
<h1>To-do List</h1>
it {{it}}
</div>
</body>
</html>

问题是由于缺少ngRoute模块的包含引起的。请查看AngularJS 1.2 $injector:modulerr
答案 2 :(得分:0)
您需要更改文件的顺序。当您在appRoutes
中注入myApp
时,应该对其进行定义。
<script src="route.js"></script>
<script src="app.js"></script>
在 app.js
中定义所有必需的模块angular.module('appRoutes', ['ngRoute']); //Define module
angular.module('myApp', ['appRoutes']);
在 route.js 中,检索已定义的appRoutes
并添加配置部分
angular.module('appRoutes')
.config(function($routeProvider){
$routeProvider
.when('/', {
templateUrl: '/views/home.html'
}
)
});
