Javascript 将特定图层嵌入谷歌地图

我的谷歌地图的嵌入代码是：

<iframe src="https://www.google.com/maps/d/embed?mid=zntuAGg8LK44.k9Si-_ekqYvk" width="640" height="480"></iframe>

因此，它从该层开始（无论是方向、定位销还是其他）

如果我能得到任何帮助，谢谢你，即使没有，也谢谢你：）

类似的内容可能会给你一个想法：

var layers = { directionslayer:null, locationpinslayer:null, whateverlayer:null };

// Create your layers (layers.directionslayer = etc.)

// e.g. https://mywebsite.com/map#directionslayer
var currentLayer = window.location.hash.slice(1).toLowerCase();

if (layers[currentLayer])
    setLayer(layers[currentLayer]);
else
    setLayer(layers.directionslayer);

function setLayer(layer){
    for (prop in layers)
        layers[prop].setMap(null);
    layer.setMap(map);
}

var layers = { directionslayer:null, locationpinslayer:null, whateverlayer:null };

// Create your layers (layers.directionslayer = etc.)

// e.g. https://mywebsite.com/map#directionslayer
var currentLayer = window.location.hash.slice(1).toLowerCase();

if (layers[currentLayer])
    setLayer(layers[currentLayer]);
else
    setLayer(layers.directionslayer);

function setLayer(layer){
    for (prop in layers)
        layers[prop].setMap(null);
    layer.setMap(map);
}
