我是 Angular JS 的新手。我在尝试学习。我创建了一个使用 grunt 和 bower 的项目。

这是我的项目结构

MyApp
|
|__app
   |
   |__bower_components
   |
   |__scripts
   | |
   | |__ app.js
   | |
   | |__contollers -- main.js, invoice.js, register.js
   | |
   | |__service -- service.js
   | |
   | |__styles -- CSS files
   | |
   | |__views -- main.html, invoice.html, register.html
   |
   |__ index.html, favicon.ico

它还包含 grunt 和 karma 文件。以下是我的 html 和 js 文件。 (只需要部分)我的 index.html

<body ng-app="MyAppInvoice">
<div class="container" ng-view=""></div>
<script src="bower_components/angular/angular.js"></script>
</body>

ma​​in.html

<div class="hero-unit">
  <a href="views/registration.html" target="_self">Register</a>
  <a href="#invoice">Invoice</a>
  <br>
</div>

invoice.html 在 div 中有一个表单。它将出现在 index.html 的 div ng-view 中。

register.html

<html>
<head>
<script src="../bower_components/angular/angular.js"></script>
<script src="../scripts/app.js"></script>
<script src="../scripts/controllers/register.js"></script>
</head>
<body ng-app="myAppRegister">
<div ng-controller="registerContoller">
<form>
<!-- Form Components -->
</form>
</div>
</body>
</html>

app.js

'use strict';

angular.module('MyAppInvoice', [])
  .config(function ($routeProvider,$locationProvider) {
    $routeProvider
        .when('/', {
          redirectTo: '/main'
        })
      .when('/invoice', {
        templateUrl: 'views/invoice.html',
        controller: 'FileUploadController'
      })
      .when('/main', {
        templateUrl: 'views/main.html',
        controller: 'MainCtrl'
      })
      .otherwise({
        redirectTo: '/main'
      });
    /*$locationProvider.html5Mode(true);*/
  });

angular.module('myAppRegister', [])
.config(function ($routeProvider,$locationProvider) {
  /*$routeProvider
        .when('/', {
          redirectTo: '/signUp'
        })
    .when('/signUp', {
      templateUrl: 'views/registration.html',
      controller: 'SignUpController'
    })
    .otherwise({
      redirectTo: '/signUp'
    });*/
});

所有其他 JS 都工作正常。

1. 在主页面我放了<a href="views/registration.html" target="_self">Register</a>这样整个页面都会发生变化，而不仅仅是 ng-view。但在 URL 中显示为 http://localhost:9000/views/registration.html .我想将其显示为 http://localhost:9000/signUp仅有的。我该怎么做？

2. 当我点击发票链接时，它正在查看发票页面并且工作正常。但是当我添加 $locationProvider.html5Mode(true); (你可以看到我已经评论了)链接网址变成了http://localhost:9000/main#invoice而不是 http://localhost:9000/#invoice

我该如何解决这些问题？

更新 1

正如 gab 建议的那样，我做到了。它工作正常。但问题是，当我输入

http://localhost:9000/login , 然后显示

Cannot GET /login

它只在我点击链接时有效。然后我必须开始表格 http://localhost:9000/

最佳答案

你必须做一些改变。首先，正如 Srivastva 所说，您必须调用路由名称而不是模板。

路由文件:

.when('/reg', {
    templateUrl: 'views/registration.html'
})

将 html5mode 设置为 true 你的 href 标签应该是这样的:

<a href="reg">Register</a>

此外，为了工作，您必须在文档的 HEAD 中添加:

<head>
    <base href="/" />
</head>

将 html5mode 设置为 false 你的 href 标签应该是这样的:

<a href="#/reg">Register</a>

为了在服务器上处理 html5，我为 yeoman 使用了这个 Angular 生成器。 Html5 已捆绑，livereload，...这是文档:angular-generator-fullstack

仅供引用，可能会有帮助，这是我的 grunt 文件:

    // Generated on 2013-12-19 using generator-angular-fullstack 1.0.1
'use strict';

// # Globbing
// for performance reasons we're only matching one level down:
// 'test/spec/{,*/}*.js'
// use this if you want to recursively match all subfolders:
// 'test/spec/**/*.js'

module.exports = function (grunt) {

  // Load grunt tasks automatically
  require('load-grunt-tasks')(grunt);

  // Time how long tasks take. Can help when optimizing build times
  require('time-grunt')(grunt);

  // Define the configuration for all the tasks
  grunt.initConfig({

    // Project settings
    yeoman: {
      // configurable paths
      app: require('./bower.json').appPath || 'app',
      dist: 'public',
      views: 'views'

        options: {
          script: 'server.js',

        }
      }
    },

快速服务器的配置:

    'use strict';

// Module dependencies.
var express = require('express'),
    path = require('path');

var app = express();


// Express Configuration
app.configure('development', function(){
  app.use(require('connect-livereload')());
  app.use(express.static(path.join(__dirname, '.tmp')));
  app.use(express.static(path.join(__dirname, 'app')));
  app.use(express.errorHandler());
  app.set('views', __dirname + '/app/views');
});

app.configure('production', function(){
  app.use(express.favicon(path.join(__dirname, 'public', 'favicon.ico')));
  app.use(express.static(path.join(__dirname, 'public')));
  app.set('views', __dirname + '/views');
});

app.configure(function(){
  app.engine('html', require('ejs').renderFile);
  app.set('view engine', 'html');
    app.use(express.logger('dev'));
    app.use(express.bodyParser());
    app.use(express.methodOverride());

  // Router needs to be last
    app.use(app.router);
});

// Controllers
var api = require('./lib/controllers/api'),
    controllers = require('./lib/controllers');

// Server Routes
app.get('/api/awesomeThings', api.awesomeThings);

// Angular Routes
app.get('/partials/*', controllers.partials);
app.get('/*', controllers.index);

// Start server
var port = process.env.PORT || 3000;
app.listen(port, function () {
  console.log('Express server listening on port %d in %s mode', port, app.get('env'));
});
