我的问题可以在以下最小例子中重现：
https://leafletjs.com/examples/layers-control/example.html
当您在触摸设备上打开网站或模拟桌面上的触摸事件并点击右上角的控件时，它会打开，一旦您点击地图，它就会再次关闭。预计会有这么多，但是当控件打开时单击标记时，弹出窗口会打开，但控件不会关闭。
这在示例中无关紧要，但在我的应用程序中，大多数地图都包含带有弹出框的折线，这使得移动用户很难关闭控件，因为他们必须在所有折线之外点击才能使其工作。
有没有办法配置Leaflet（或事件处理程序）来关闭弹出窗口的控件？
您可以将cities变量分配给L.featureGroup，然后通过删除指示扩展控件的.leaflet-control-layers-expanded类来点击标记，然后收听onclick事件。
var cities = L.featureGroup();
...
cities.on('click', function() {
document.getElementsByClassName('leaflet-control-layers')[0]
.classList.remove('leaflet-control-layers-expanded');
})
