我是 Angular 和 Express 框架的新手。我正在开发一个简单的服务器，它响应给定的路由并显示在 Controller 中声明的变量的值。但是出现了一个错误，例如 Controller 未定义。这里为了方便起见， Controller 存储在 client/js/controllers 文件夹中 整个项目的代码在这里

meetups-controller.js
function meetupsController ($scope) {
$scope.meetupsCount = 10;
// $scope.meetups = [
// { name : "Meet 1"},
// { name : "Meet 2"},
// { name : "Meet 3"}
// ]
// $scope.createMeetup = function () {
// $scope.meetups.push({ name : $scope.meetupsName});
// $scope.meetupsName = '';
// }
}
main.js
// console.log("Hello from node");
//Express server
var express = require('express');
app = express();
app.get('/' , function(req ,res) {
res.sendFile(__dirname + '/client/views/index.html');
});
app.use('/js',express.static(__dirname +'/client/js'));
app.listen(3000 ,function () {
console.log('Im Listening .... ');
});

最佳答案
您尚未定义 Angular 应用 (ng-app="")，也未在 Angular 应用中注册您的 Controller 。
meetups-controller.js(添加在文件底部):
var app = angular.module('myApp', []);
app.controller('meetupsController', meetupsController);
index.html(更改):
<html ng-app="myApp">
关于javascript - 参数 'meetupsController' 不是函数，出现未定义错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/36821145/
