有没有办法触发 itemController 中定义的操作。当我用 <button {{action 'inItem' }}> 触发操作时，它会抛出未捕获错误:没有处理事件“inItem”。。如果我使用 <button {{action 'inItem' target=item}}> 设置操作目标，它会抛出错误，Uncaught TypeError:无法读取未定义的属性“apply”。
如何触发 itemController 中定义的操作。
App = Ember.Application.create({
LOG_TRANSITIONS: true
});
App.Router.map(function(){
this.resource('posts');
});
App.PostsRoute = Ember.Route.extend({
model: function(){
return [
{title: 'success'},
{title: 'winning'},
{title: 'breakthrough'}
];
}
});
App.PostsController = Ember.Array.extend({
itemController: 'post'
});
App.PostController = Ember.ObjectController.extend({
isSelected: false,
actions: {
inItem: function(){
this.set('isSelected', true);
//alert('hi');
}
}
});<!DOCTYPE html>

<button {{action 'inItem' target=item}} {{bind-attr class="isSelected"}}> call itemcontroller action </button>
{{/each}}
</script>

您的 Controller 应该扩展ArrayController，而不是Array。
App.PostsController = Ember.ArrayController.extend({
itemController: 'post'
});
