我无法访问我的数组控制器变量。我有这个简单的应用程序,例如:
App.js
App = Ember.Application.create();
App.ApplicationAdapter = DS.FixtureAdapter.extend();
App.Router.map(function() {
this.route('hello');
});
App.IndexRoute = Ember.Route.extend({
redirect: function() {
this.transitionTo('hello');
}
});
App.HelloController = Ember.ArrayController.extend({
name: 'tom'
});
App.HelloRoute = Ember.Route.extend({
model: function() {
return this.store.find('hello');
}
});
App.Hello = DS.Model.extend({
title: DS.attr('string')
});
App.Hello.FIXTURES = [{
id: 1,
title: 'hello'
},{
id: 2,
title: 'hello'
}];
我的观点是:
<script type="text/x-handlebars" data-template-name="application">
<h2>Welcome to Ember.js</h2>
{{outlet}}
</script>
<script type="text/x-handlebars" data-template-name="hello">
{{#each}}
{{title}} {{name}}
{{/each}}
</script>
当我保存这段代码时,页面只渲染“hello”“hello”,我希望“你好汤姆”“你好汤姆”。我做错了什么?
感谢帮助!

问题是您正在将每个语句中的上下文更改为模型,因此您不再在上下文中使用该名称。
http://emberjs.jsbin.com/UzUxIwa/1/edit
<script type="text/x-handlebars" data-template-name="hello">
{{#each item in controller}}
{{item.title}} {{controller.name}}
{{/each}}
</script>
老实说甚至比使用itemController更好,并将属性放在该控制器上
http://emberjs.jsbin.com/UzUxIwa/2/edit
App.HelloController = Ember.ArrayController.extend({
itemController:'singleHello'
});
App.SingleHelloController = Ember.ObjectController.extend({
name: 'tom'
});
{{#each item in controller}}
{{item.title}} {{item.name}}</br>
{{/each}}
