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>
我可以正确显示隐藏它使用loadingModal.show();和loadingModal.hide();
但是我怎么知道它在Angular中是显示还是隐藏？
显然,我不那么优雅的解决方案毕竟不是那么优雅:D
这是一个拉取请求,显示isShown()我猜的应该可用的方法
在内部,该函数看起来与此答案中的内容类似
isShown() {
return this.style.display !== 'none';
}
不是超级优雅的解决方案,但它的工作原理
if( $scope.loadingModal._element.css('display') == 'none'){
// hidden now
}else{
// visible now
}
