来自变量/属性的ui-sref(ui-sref from variable / attribute)

 我正在将我的SPA从ng-route过渡到ui.router。 对于某人来说，这应该是一个快速的... 
 
 对于我的一些州，我定义了$rootScope.nextState和$rootscope.prevState属性（ $rootscope.prevState strings），这样我的导航栏上就可以有上一个和下一个按钮/链接。 
 
 我似乎无法得到正确的链接。 我努力了： 
 
<button ui-sref="{{prevState}}">Previous</button>

<button ui-sref={{prevState}}>Previous</button>

<button ui-sref="{prevState}">Previous</button>

<button ui-sref="prevState">Previous</button>

<button ng-href="{{$state.href(prevState)}}">Previous</button>

<button ng-click="$state.go(prevState)">Previous</button>
 
 所有上述内容<a>代替。 
 
 全部抛出“无效状态引用”错误或不更改状态。 如何在ui-router中使用statename的动态属性？ 
 
 我尽我所能阅读并理解了文档。 类似的问题没有帮助： https ： //stackoverflow.com/questions/23476296/dynamically-constructed-ui-sref-attribute-in-ui-router和https://stackoverflow.com/questions/24349731/dynamically-设定的值-的-UI-SREF-angularjs 
 
 这是一个重新发现问题的Plunker 。 它在类似于angular-ui-router-title的方法中使用resolve。 这可能是问题的时机问题...... 

I am transitioning my SPA from ng-route to ui.router. This should be a quick one for someone...
 
For some of my states, I have $rootScope.nextState and $rootscope.prevState attributes defined (statename strings), so that I can have Previous and Next buttons / links on my navbar.
 
I can't seem to get the link correct. I have tried:
 
<button ui-sref="{{prevState}}">Previous</button>

<button ui-sref={{prevState}}>Previous</button>

<button ui-sref="{prevState}">Previous</button>

<button ui-sref="prevState">Previous</button>

<button ng-href="{{$state.href(prevState)}}">Previous</button>

<button ng-click="$state.go(prevState)">Previous</button>
 
All of the above with <a> instead.
 
All throw an "Invalid state ref" error or don't change the state. How can you use a dynamic attribute for statename in ui-router?
 
I have read and understood the docs to the best of my ability. Similar questions that haven't helped: https://stackoverflow.com/questions/23476296/dynamically-constructed-ui-sref-attribute-in-ui-router and https://stackoverflow.com/questions/24349731/dynamically-set-the-value-of-ui-sref-angularjs
 
Here's a Plunker recreating the problem. It uses resolve in a method similar to angular-ui-router-title. It might be the timing of things that's the issue...
