有没有办法将数组传递给currentEhen在EmberJS中？

Question

我正在尝试在多个路由上保持“活动”，例如/＃/ users和/＃/ user。

任何想法？

Answer 1

这是一个彻头彻尾的黑客，但它在Ember 1.0.0中起作用。生成链接到用户保持活跃，当用户路由活跃：

App.UserRoute = Ember.Route.extend({ 

    activate: function() { 
     setTimeout(function() { 
      $('[href="#/users"]').addClass("active"); 
     }, 0); 
    } 
});

您可以重新打开Ember的LinkView，做这样的事（让currentWhen包含空格分隔值）

Ember.LinkView.reopen({ 
    active: function() { 
     // we allow link-to's currentWhen to specify multiple routes 
     // so we need to check each one of them 
     var loadedParams = Ember.get(this, 'loadedParams'); 
     var currentWhen = this['current-when'] || this.currentWhen; 
     currentWhen = currentWhen || (loadedParams && loadedParams.targetRouteName); 

     if (currentWhen && currentWhen.indexOf(' ') >= 0) { 
       var currents = currentWhen.split(' '); 
       router = Ember.get(this, 'router'); 

      for (var i = 0; i < currents.length; i++) { 
       var isActive = router.isActive.apply(router, [currents[i]]); 
       if (isActive) 
        return isActive; 
      } 

      return false; 
     } 

     return this._super(); 
    }.property('resolvedParams', 'routerArgs') 
});
