由于我的上一个问题答案如此之快,而我对另一个问题感到迷茫,即使我没有时间查看最后一个问题的答案,我也已经问了另一个问题。
所以,我想在传单的Layer控制面板中插入一个下拉菜单来管理一些不同距离的缓冲区域,当我点击时,它会触发标记(或折线)它
现在我试着进入leaflet-src.js并修改了LayerControl,但由于我不知道自己在做什么,所以我只是模仿了我看到的其他选项(baselayer和覆盖)。理想情况下,我希望有一个动态图层,一次只绘制一个缓冲区,只有在LayerControl面板中检查我的图层,并且缓冲区的大小根据所选距离。以下是我用来说明我的情况的代码:
<!DOCTYPE html>
<head>
<title>Example</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<script src="https://unpkg.com/leaflet@1.0.2/dist/leaflet.js"></script>

#map{

<div id="map"></div>
<script>
var sites = [
{'loc':[42.2793869135936,9.53257201027757],'title':'TORRA A I CASELLI'},
{'loc':[42.2713622720985,9.50678498185463],'title':'TOUR GIANDINELLI'},
{'loc':[42.641518105666,9.00587322013212],'title':'TOUR DE LOSARI'},];
var map = new L.Map('map');
var osm = map.addLayer(new L.TileLayer('http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png'));
map.setView([42.5,9.2210706018535],9);
var marks = new L.LayerGroup();
for(i in sites) {
var title = sites[i].title,
loc = sites[i].loc,
markersites = new L.Marker(new L.latLng(loc), {title: title});
markersites.bindPopup('<strong>'+title+'</strong><br>');
marks.addLayer(markersites);
}
marks.addTo(map);
// for now it is all good, the next part is where I fail, please notice the extra overlay I put as a comment and which should include my selectable, checkable, dropdown menu
var baseLayers = {
"OpenStreetMap": osm
};
var overlays = {
"Sites":marks,
/*"Distance":...,*/
};
L.control.layers(baseLayers, overlays,{collapsed:false, hideSingleBase:true}).addTo(map);
</script>
</body>
</html>
由于我没有找到任何接近我想要的东西,我只希望有人能够有一个想法(以及更好的网络代码知识),让任何事情都指向我的好方向
感谢您的关注。 干杯, 纪尧姆
