我的滑块不会在第一次导航页面时出现.然而,当我硬刷新页面然后它出现时,如果我用页面内容替换<div ng-view></div>代码,front.html那么滑块也开始工作.让我知道我在角度上做错了什么,因为我认为这是我所缺少的基本功能.
以下是我的布局代码 -
<!DOCTYPE html>
<html ng-app="myApp">
<head>
<meta charset="utf-8" />
<title>WEBSITE</title>
<link rel="stylesheet" href="assets/css/style.css" />
<link rel="stylesheet" href="assets/css/flexslider.css" type="text/css" media="screen" />
<script src="https://oss.maxcdn.com/libs/html5shiv/3.7.0/html5shiv.js"></script>
<script src="assets/js/jquery.js"></script>
<script src="assets/js/jquery.flexslider.js"></script>
<script src="assets/js/angular.js"></script>
<script src="assets/js/angular-route.js"></script>
<script src="controllers/mainController.js"></script>
<script>
jQuery(document).ready(function($) {
jQuery(window).load(function() {
jQuery('.flexslider').flexslider({
animation: "slide"
});
});
});
</script>
</head>
<body ng-controller="mainController">
<header ng-include="'includes/header.html'"></header>
<nav ng-include="'includes/navmenu.html'"></nav>
<div ng-view></div>
<footer ng-include="'includes/footer.html'"></footer>

</html>
以下是我的主控制器代码 -
var myApp = angular.module('myApp', ['ngRoute']);
myApp.config(function($routeProvider){
$routeProvider
.when('/', {
templateUrl: 'views/pages/front.html',
controller: …我想使用MEAN.io堆栈.我做了必要的初始化.创建了文件夹,安装了npm,获得了库.
现在在server/config/express.js我有
assetmanager = require('assetmanager'),
和
// Import your asset file
var assets = require('./assets.json');
assetmanager.init({ // this is line 75
js: assets.js,
css: assets.css,
debug: (process.env.NODE_ENV !== 'production'),
webroot: 'public/public'
});
这给了我这个错误:
server/config/express.js:75
assetmanager.init({

[nodemon] app crashed - waiting for file changes …我克隆了meanjs并在启动时使用npm install和grunt运行它显示调试器在端口5858上侦听,但是当我打开chrome时
本地主机:8080 /调试端口= 5858
它显示网页不可用.有什么我需要做的让node-inspector调试器为meanjs工作？
最近我开始使用MeanJs,它非常棒,但我不明白一些东西.我需要为我的后端创建一个简单的用户管理.
从官方博客他们说:
新的可用性功能:为用户模型添加了角色 - 默认为"用户"和"管理员",您可以根据需要添加和删除它们.
搜索后我发现了一些例子,但所有这些都是关于meanio,而不是meanjs,有一个包含MEAN-ADMIN的meanio,它为我们做了但是在我找不到的meanjs.
有人知道实施用户管理的最佳方法吗？一些例子？
多谢你们.
我正在关注需要我快速安装的MEAN堆栈教程:
我运行这个:
npm install -g express-generator
这是我的结果:
username@username-Inspiron-3521:~$ npm install -g express-generator
/home/username/npm/bin/express -> /home/username/npm/lib/node_modules/express-generator/bin/express
express-generator@4.13.1 /home/username/npm/lib/node_modules/express-generator
??? sorted-object@1.0.0
??? mkdirp@0.5.1 (minimist@0.0.8)
??? commander@2.7.1 (graceful-readlink@1.0.1)
但是当我这样做的时候
express --ejs flapper-news
The program 'express' is currently not installed. You can install it by typing:
sudo apt-get install node-express
我究竟做错了什么？
谢谢你的时间.
