我正在尝试渲染一个在它的两个孩子之间切换的视图(或者我希望如此)并且某些东西并不完全有效。这是我的模板:
{{#view App.LoginFormView isVisibleBinding="user.isNotAuthenticated" }}
Username: {{view Ember.TextField valueBinding="user.loginName"}} /
Password: {{view Ember.TextField valueBinding="user.userPassword" type="password"}}
<button class="btn" {{ action "login" }} {{bindAttr disabled="user.isNotValid"}}>Login</button>
{{/view}}
{{#view App.LoginInfoView isVisibleBinding="user.isAuthenticated" }}
You are logged in as {{user.loginName}}. Click <a {{action "logout"}}>here</a> to logout
{{/view}}
在 app.js 我有以下内容:
App.User = Ember.Object.extend({
loginName:'',
userPassword:'',
rememberMe:true,
isNotValid:function(){
return (this.get("loginName") == '') || (this.get("userPassword") == '');
}.property('loginName', 'userPassword'),
isAuthenticated:false,
isNotAuthenticated:function(){
return !this.isAuthenticated;
}.property('isAuthenticated')
});
App.AuthenticationController = Ember.Controller.extend({
login:function() {
alert("loginName:"+this.user.get('loginName')+";\n"+
"userPassword:"+this.user.get('userPassword')+";\n"+
"rememberMe:"+this.user.get('rememberMe')+";\n");
this.user.isAuthenticated = true;
},
user:App.User.create()
});
App.AuthenticationView = Ember.View.extend({
templateName: 'authentication',
userBinding:"App.AuthenticationController.user"
});
App.LoginFormController = Ember.Controller.extend({
userBinding:"App.AuthenticationController.user"
});
App.LoginFormView = Ember.View.extend();
App.LoginInfoController = Ember.Controller.extend({
userBinding:"App.AuthenticationController.user"
});
App.LoginInfoView = Ember.View.extend();
App.Router = Ember.Router.extend({
enableLogging:true,
root: Ember.Route.extend({
index: Ember.Route.extend({
route: '/',
connectOutlets: function(router){
router.get('applicationController').connectOutlet('authentication','authentication');
},
login:function(router){
router.get('authenticationController').login();
}
})
})
});
我遇到的问题是视图不会切换 isAuthenticated 属性的更改。我的印象是会自动发生,但事实并非如此。关于如何使这项工作的任何想法?或者我错过了一些基本的东西(这里是ember.js新手,所以要温柔:-))
干杯,亚历克斯。
