Question

当应用程序获取某些数据时，我正在使用ons-modal来显示加载文本和微调器图标。代码如下：

<ons-modal var="loadingModal">
  <ons-icon icon="ion-load-c" spin="true"></ons-icon>
  <br><br>
  Cargando...
  <br>
</ons-modal>

我可以使用loadingModal.show();和loadingModal.hide();

正确显示隐藏信息

但是我如何知道Angular中是否显示或隐藏了它？

显然，我不那么优雅的解决方案毕竟不是那么优雅：D

Here is a pull request that shows the method isShown() that should be available soon I guess

在内部，该功能看起来类似于本回答中的内容

isShown() {
  return this.style.display !== 'none';
}

不是一个超级优雅的解决方案，但它有效

if( $scope.loadingModal._element.css('display') == 'none'){
  // hidden now
}else{
  // visible now
}

如何确定ons-modal显示的状态？
