[英]Getting Start with Ember.js Router
I want to learn using Ember.js for my next project. 我想学习使用Ember.js进行下一个项目。 So far I have read the documentation here but I saw no explanation about Router.
到目前为止,我已阅读此处的文档,但我没有看到有关路由器的解释。 Then I read the guide here but I still don't understand how to use Router properly.
然后我在这里阅读了指南,但我仍然不明白如何正确使用路由器。 I tried using Router this way, I want 2 route:
我试过这种方式使用Router,我想要2路:
/login
which displays a button to enter the second route /login
,显示用于输入第二条路线的按钮 /home
which displays a button to enter the first route /home
显示进入第一条路线的按钮 This is just a very simple code to test using Router to switch between "pages". 这只是一个非常简单的代码,用于测试使用Router在“页面”之间切换。 I tried using this code but all I get is a blank page:
我尝试使用此代码,但我得到的只是一个空白页:
<script src="js/libs/jquery-1.7.2.min.js"></script>
<script src="js/libs/handlebars-1.0.0.beta.6.js"></script>
<script src="js/libs/ember-1.0.pre.min.js"></script>
<script>
var App = Ember.Application.create();
App.ApplicationController = Ember.Controller.extend();
App.ApplicationView = Ember.View.extend();
App.LoginView = Ember.View.extend({
templateName: 'login-page'
});
App.HomeView = Ember.View.extend({
templateName: 'home-page'
});
App.router = Ember.Router.create({
enableLogging: true,
root: Ember.Route.extend({
index: Ember.Route.extend({
route: '/',
redirectsTo: 'login'
}),
login: Ember.Route.extend({
route: '/login',
doLogin: Ember.Route.transitionTo('home'),
connectOutlets: function (router) {
router.get('applicationController').connectOutlet('login');
}
}),
home: Ember.Route.extend({
route: '/home',
doLogout: Ember.Route.transitionTo('login'),
connectOutlets: function (router) {
router.get('applicationController').connectOutlet('home');
}
})
})
});
App.initialize(App.router);
</script>
<script type="text/x-handlebars" data-template-name="login-page">
<h1>Login Page</h1>
<button {{action doLogin}}>Login</button>
</script>
<script type="text/x-handlebars" data-template-name="home-page">
<h1>Home Page</h1>
<button {{action doLogout}}>Logout</button>
</script>
When I run this, the URL goes to #/login
but it display nothing. 当我运行它时,URL转到
#/login
但它什么也没显示。 Does anyone can show me how to make the above code works? 有谁能告诉我如何使上述代码有效? Why do I get a blank page?
为什么我会得到一个空白页面?
Your code: http://jsfiddle.net/jPn3H/ 您的代码: http : //jsfiddle.net/jPn3H/
...updated with a brand new 'application' template hooked up to App.ApplicationView
: http://jsfiddle.net/pauldechov/jPn3H/1/ ...使用连接到
App.ApplicationView
全新“应用程序”模板进行App.ApplicationView
: http : //jsfiddle.net/pauldechov/jPn3H/1/
The .initialize()
function appends App.ApplicationView
to <body>
for you. .initialize()
函数将App.ApplicationView
附加到<body>
。 Those .connectOutlet(...)
calls won't do much of anything unless there's an {{outlet}}
to connect. 除非有
{{outlet}}
连接,否则那些.connectOutlet(...)
调用不会做任何事情。 Hope that helps. 希望有所帮助。
