灰烬如何将LinkView与视图助手一起使用？

Question

In Ember, I want to create a link with an optional class. In the template, I should be able to define the binding, on which the optional class is set. The target HTML should look like this

<li class="completed"><a>Index</a></li> < completed
<li class="active"><a>Index</a></li> < active
<li class=""><a>Index</a></li> < in-active

So the active/in-active states can be achieved with the link-to helper;

{{#link-to "index" tagName="li"}}<a>Index</a>{{/link-to}}

However, this doesn't allow me to define the optional "complete" binding. So I'm thinking about creating a subclass of LinkView , which does provide said binding. So the next step would be to create said subclass, and implement the binding. However I don't feel like duplicating the link-to helper, and am fine with using the view helper. However I cannot figure out how the view helper is supposed to work with LinkView :

{{#view Ember.LinkView "index" }}Index{{/view}}

DEPRECATION: Global lookup of Ember.LinkView from a Handlebars template is deprecated.
Uncaught TypeError: Cannot read property 'length' of undefined

{{#view Ember.LinkView target="index" }}Index{{/view}}

DEPRECATION: Global lookup of Ember.LinkView from a Handlebars template is deprecated.
Uncaught TypeError: Cannot read property 'length' of undefined

I've been reading both the source of LinkView and link-to , but can't figure out how to proceed.

您可以像这样使用类绑定

{{#link-to 'index' tagName='li' class="active:active completed:completed"}}<a href="#">Index</a>{{/link-to}}
