Ember链接 - 立即设置活动类 [英] Ember link-to Set Active Class Immediately

问题描述

我有一个导航栏，具有特殊的CSS，当链接具有active类时。它看起来像这样：

I have a nav bar that has special CSS that shows up when a link has the "active" class on it. It looks something like this:

<ul>
    <li>{{link-to "routeName"}}<i class="icon-up"></i>{{/link-to}}</li>
    {{!-- more list items like the previous one... --}}
</ul>

但是，当我点击链接routeName，一个相当昂贵的查询是有时可能很慢。我有一个 LoadingRoute 设置一个包含一个简单的微调器的加载视图，但似乎链接没有收到活动 / code>类，直到路由的承诺得到解决。有没有Handlebars友好的方式来告诉链接到，以便在点击时立即设置活动类？

However, when I click on the link with "routeName", a rather expensive query is made that may be slow at times. I have a LoadingRoute set up with a loading view that consists of a simple spinner, but it seems like the link does not receive the "active" class until the route's promise is resolved. Is there a Handlebars-friendly way to tell link-to to immediately set the "active" class when it is clicked?

推荐答案

这样做的原因是网址在转换结束之前不会更新。感谢Ember IRC和Machty中的窥视，这是一个已经解决的问题，将在下一个测试周期。

The reason for this is that the URL does not get updated until the end of a transition. Thanks to the peeps in the Ember IRC and Machty, this is an issue that has been resolved and will be in the next beta cycle.
