我设法通过我的把手模板将attributeBinding设置为控制器上下文:
<li {{bindAttr class="view.controller.isSelected:active:"}}>
<a href="#" {{action "toggleSelected"}}>{{view.controller.title}}</a>
</li>
在这样的每个组中调用:
<ul class="nav nav-tabs nav-stacked">
{{#each skill in controller}}
{{view App.SkillView}}
{{/each}}
</ul>
但我发现EmberJS在每个视图周围添加了div,导致我的CSS出现问题所以我从模板中删除了li
标签,并在SkillView
中设置了tagName,并尝试通过JS实现了attributeBinding在我想要的地方添加li DOM元素的对象,但我使用的attributeBindings似乎不起作用:
App.SkillView = Ember.View.extend({
templateName: 'skill',
tagName: 'li',
attributeBindings: ['controller.isSelected:active:']
});
这也不是:
App.SkillView = Ember.View.extend({
templateName: 'skill',
tagName: 'li',
attributeBindings: ['view.controller.isSelected:active:']
});
也不是这样:
App.SkillView = Ember.View.extend({
templateName: 'skill',
tagName: 'li',
attributeBindings: ['isSelected:active:']
});
如何在视图绑定字符串的上下文中从视图中引用控制器?我在Handlebars模板上做了什么,我没有在View代码中做什么?
答案 0 :(得分:1)
原来我应该使用classNameBindings而不是attributeBindings。以下工作:
App.SkillView = Ember.View.extend({
templateName: 'skill',
tagName: 'li',
classNameBindings: ['controller.isSelected:active:']
});
