如何从离子标签打开离子模态 [英] How to open an Ionic Modal from an Ionic Tab

问题描述

我有一个用例，我想通过单击Ion选项卡打开Ionic Modal。

I have a use case where I'd like to open an Ionic Modal by clicking an Ion Tab.

我们的应用程序有4个固定的 ion-tabs 。其中一个选项卡目前转到评论表单，但它更适合作为模态（因此用户可以快速完成表单并返回到他们正在做的事情）。

Our app has 4 fixed ion-tabs. One of the tabs currently goes to a comment form but it would be better suited as a modal (so the user can quickly complete the form and go back to what they were doing).

模态通常附加在按钮上。我试图在选项卡上使用 ng-click 打开模态，类似于演示但没有运气。

Modals are normally attached to a button. I've attempted to open the modal using ng-click on the tab, similar to this demo but with no luck.

是否可以使用 ion-tab 打开离子模式？

推荐答案

您可以在标签中添加假标签：

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>

如你所见，最后一个是空的：

As you can see the last one is empty:

<ion-tab title="D" ng-click="openMyModal()">
</ion-tab>

我们点击选项卡（ng-click）它调用方法 openMyModal 。

We you click to the tab (ng-click) it calls a method openMyModal.

由于我没有为该选项卡定义控制器，我将使用控制器作为抽象选项卡：

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'
})

这将是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();
  }; 

}) 

如果你想在行动中看到它k这个 plunker 。

If you want to see it in action check this plunker.
