Question

我正在使用Ionic v1 Angular

这是我的代码：

$scope.back = function () {        
    $ionicHistory.goBack();
    // window.history.back(); //this works but not working on device hardware back button
    console.log($ionicHistory.currentView()); //url: app/home
    console.log($ionicHistory.backView()); //url: app/home
};

这是我的按钮：

<button ng-hide="current_state == 'app.home'" class="button button-clear" menu-toggle="left" ng-click="back()" id="back_button">back</button>

如果要控制硬件按钮，则必须注册并覆盖硬件后退按钮的默认操作

  // Disable BACK button on home
  $ionicPlatform.registerBackButtonAction(function (event) {
    if($state.current.name=="app.home"){  // if you are in home page you can close the app
      navigator.app.exitApp();
    }
    else { // otherwise you just go back to previous statein the history
      navigator.app.backHistory();
    }
  }, 100);

后退按钮不起作用：$ ionicHistory.backView（）与currentView相同
