现象

点击地图上的图标，然后sheetShow 为true，弹框一闪而过

探究

地图图标点击，然后呢，设置sheetShow 为true，弹出van-action-sheet，逻辑上是没错的，我把这个代码放在地图外的控件，是可以正确弹出对话框的，然后在浏览器模式下，是正常能弹出的，切换成手机模式，又不能弹出

如果是van-action-sheet问题，在地图外的地方能弹出，就应该能排除，如果是地图图标点击代码的问题，在浏览器模式下又能弹出，也就不存在兼容性的问题了，很难排查
后来和公司前端大佬交流，找到了问题，地图图标点击的时候，会刷新地图，van-action-sheet刚弹出来，地图刷新了，van-action-sheet就消失了，所以才出现一闪而过，这样就好解决了，在点击事件里边，加一个延时，刷新完了，在弹出对话框

 var onMarkerClick = function (e) {console.log("marker 点击");that.hospital = item;setTimeout(() => {that.sheetShow = true;}, 100);};

我这边试了一下this.$nextTick，没有效果，就先加个延时吧
