use*_*080 5 data-visualization cartography mapbox mapbox-gl-js
我想在 Mapbox GL JS 中的图层之间切换。我创建了一些单选按钮，它们在一定程度上起作用，您可以从一层切换到另一层，但不能来回切换。
下面是到目前为止我用于切换图层的代码：
var layerList = document.getElementById('toggle');
var inputs = layerList.getElementsByTagName('input');
function switchLayer(layer) {
var layerId = layer.target.id;
map.setLayoutProperty(layerId, 'visibility');
}
for (var i = 0; i < inputs.length; i++) {
inputs[i].onclick = switchLayer;
}
这是其余的代码（简化）和 jsbin 的链接https://jsbin.com/cigekutiho/edit?html,output

Map.setLayoutProperty有 3 个参数(layer, name, value)。因此，要使图层不可见，请使用：
map.setLayoutProperty('my-layer', 'visibility', 'none');
然后要使其再次可见，请使用：
map.setLayoutProperty('my-layer', 'visibility', 'visible');
