根据文件夹内容暂停apache camel路由(Suspending an apache camel route depending of a folder content)

 您可以在标签中添加“假”标签： 
 
<ion-tabs class="tabs-royal tabs-striped">
    <ion-tab title="A" href="#/tab/a">
        <ion-nav-view name="a-tab"></ion-nav-view>
    </ion-tab>
    <ion-tab title="B" href="#/tab/b">
        <ion-nav-view name="b-tab"></ion-nav-view>
    </ion-tab>
    <ion-tab title="C" href="#/tab/c">
        <ion-nav-view name="c-tab"></ion-nav-view>
    </ion-tab>
    <ion-tab title="D" ng-click="openMyModal()">
    </ion-tab>    
</ion-tabs>
 
 如您所见，最后一个是空的： 
 
<ion-tab title="D" ng-click="openMyModal()">
</ion-tab>
 
 我们点击选项卡（ng-click），它调用方法openMyModal 。 
 
 由于我没有为该选项卡定义控制器，因此我将使用控制器作为抽象选项卡： 
 
.state('tab', {
    url: '/tab',
    abstract: true,
    templateUrl: 'tabs.html',
    controller: 'TabsController'
})
 
 这将是控制器TabsController： 
 
.controller('TabsController', function($scope, $ionicModal){

  $scope.modal = null;

  $ionicModal.fromTemplateUrl('my-modal.html', {
      scope: $scope,
      animation: 'slide-in-up'
    }).then(function(modal) {
      $scope.modal = modal;
    });

  $scope.openMyModal = function()
  {
    $scope.modal.show();
  };

  $scope.closeModal = function() {
    $scope.modal.hide();
  }; 

}) 
 
 如果你想看到它的实际效果，请检查这个plunker 。 

You can add a "fake" tab to your tabs:
 
<ion-tabs class="tabs-royal tabs-striped">
    <ion-tab title="A" href="#/tab/a">
        <ion-nav-view name="a-tab"></ion-nav-view>
    </ion-tab>
    <ion-tab title="B" href="#/tab/b">
        <ion-nav-view name="b-tab"></ion-nav-view>
    </ion-tab>
    <ion-tab title="C" href="#/tab/c">
        <ion-nav-view name="c-tab"></ion-nav-view>
    </ion-tab>
    <ion-tab title="D" ng-click="openMyModal()">
    </ion-tab>    
</ion-tabs>
 
As you can see the last one is empty:
 
<ion-tab title="D" ng-click="openMyModal()">
</ion-tab>
 
We you click to the tab (ng-click) it calls a method openMyModal. 
 
Since I haven't defined a controller for that tab I am going to use the controller for the abstract tabs:
 
.state('tab', {
    url: '/tab',
    abstract: true,
    templateUrl: 'tabs.html',
    controller: 'TabsController'
})
 
and this would be the controller TabsController:
 
.controller('TabsController', function($scope, $ionicModal){

  $scope.modal = null;

  $ionicModal.fromTemplateUrl('my-modal.html', {
      scope: $scope,
      animation: 'slide-in-up'
    }).then(function(modal) {
      $scope.modal = modal;
    });

  $scope.openMyModal = function()
  {
    $scope.modal.show();
  };

  $scope.closeModal = function() {
    $scope.modal.hide();
  }; 

})
