Custom Leaflet layer control

I have 7 leaflet maps created via loop and data which is exactly the same on each map controlled by a checkbox; however, my plan was to make one layer visible per map. I have searched for a solution where my maps can remain while having one layer per map, but to no avail. I had the idea of keeping one of each layer on by default when the page loads in, but I can't seem to find anything on that either. Does anyone know how to do that? I have left one layer's coordinates in the code Toe_11000 (the "11000 years ago" checkbox) since my coordinates went over the character limit but please let me know if you need clarification. If you need more of the coordinates for the layers, the full code can be found in this JSFiddle: https://jsfiddle.net/wpc6707/3ksjh06p/21/
Here's my code:

You were on the right direction!
So, if you use all your data inside glacier_map_Data, where the properties reflect the data-* attribute of each element in the Document i.e: <div data-map="glacier_1"></div> add inside it also the properties label, shape and style :
Here's the "new" data example for every glacier_(N)
// glacier_* :
{
center: [45.5, -89.5],
zoom: 7,
label: "11000 years ago",
description: "Glacier one description info goes here...",
shape: {
type: "FeatureCollection",
features: [
{
type: "Feature",
geometry: {
type: "Polygon",
coordinates: [[/* .... */],],
},
properties: { /* .... */ },
},
],
},
style: {
color: "#e41a1c",
}
},
having that kind of data, you first need to:
Create all the LeafLet layers
Create all the LeafLet layers inside a separate Object. You'll later add that object to every map:
// Create the L.geoJSON LAYERS to be later added to each map!
const overlays = Object.entries(glacier_map_Data).reduce((acc_obj, [key, data]) => {
// Define the geoJSON layer instance
const L_geoLSON = L.geoJSON(data.shape, {style: data.style});
// Add click listener to layer
L_geoLSON.on({
click() {
EL_panel.innerHTML = `<h2>${data.title}</h2><p>${data.description}</p>`;
}
});
// Create the return Object:
acc_obj[key] = {
label: data.title,
L_geoJSON
};
// Return the accumulator (see: MDN: Array.prototype.reduce() for more info)
return acc_obj;
}, {});
the above will generate something similar as what you used in your code for var glacierLayers but - with a slight difference:
// overlays =
{
glacier_1 : {
label: "11000 years ago",
L_geoJSON: {} // the LeafLet geoJSON instance
},
// glacier 2, 3 etc...
}
having that custom object in place now, all you need is to: when looping your Maps convert it to the format expected by LeafLet {"layer description 1": geoJSON, /* etc */}
Add multiple layers to LeafLet map and make respective one active:
while looping your Maps ELements, you get the current element's data-* attribute const id = EL.dataset.map ID - that ID can be now referenced to get the active layer too:
// Maps initializator
// Applays LeafLet to each map Element `EL`
const initMap = (EL) => {
const id = EL.dataset.map; // gives back i.e: "glacier_1" 2, 3 etc...
const data = glacier_map_Data[id];
// Assign a LeafLet Map instance to a specific DOM element and set its view
const L_map = L.map(EL).setView(data.center, data.zoom);
L.tileLayer(L_basemapTile, L_basemapOptions).addTo(L_map);
// Convert the
const overlayMaps = Object.values(overlays).reduce((acc_obj, data) => {
acc_obj[data.label] = data.L_geoLSON
return acc_obj;
}, {});
// Add control layers to map:
L.control.layers(null, overlayMaps).addTo(L_map);
// Make specific one "Active" (checked!) and visible on map:
L_map.addLayer(overlays[id].L_geoJSON);
};
That's basically it. See in the below example how the click handlers are resolved to make it all work:
const EL_panel = document.querySelector("#panel");
const L_basemapTile = "https://stamen-tiles-{s}.a.ssl.fastly.net/terrain-background/{z}/{x}/{y}.{ext}";
const L_basemapOptions = {

display a pieChart in mapbox popup

I want to display a pieChart to show my data when I click the point.
//html part
<div id="map"></div>
//javaScript
<script >
var peopleJSON = [{
"type": "Feature",
"geometry": {
"type": "Point",
"coordinates": [144.961027, -37.795947]
},
"properties": {
"building_name": "Art West",
"student": 100,
"staff": 200,
"total": 300,
}
},
map.on('load', function(){
map.addLayer({
'id': 'test',
'type': 'circle',
'source' : {
"type": "geojson",
"data": {
"type": "FeatureCollection",
"features": peopleJSON,
}
},
'paint':{
'circle-color': '#00b7bf',
'circle-radius':8
'circle-stroke-width': 1,
'circle-stroke-color': '#333',
}
});
map.on('click', 'test', function (e) {
new mapboxgl.Popup()
.setLngLat(e.lngLat)
.setHTML(
"Building Name: " + e.features[0].properties.building_name
+ "<br> detail: " + e.features[0].properties.detail
+ "<br> total: " + e.features[0].properties.total
)
.addTo(map);
});
})
</script>
Now, my code just shows the text of data.
Can I create a div element in popup and use any external api(such as google chart) to access data and create piechart into the div?

How can I display multiple MapBox maps on a Squarespace page?

I want to show 2 Mapbox maps side to side on the same page.
The SF map works as advertised (popup on hover), but the NY map does not show its markers. What am I doing wrong?
Thanks much!
Here is the page with a NY and a SF map: link.
In that page header I injected:
<script src='https://api.mapbox.com/mapbox-gl-js/v0.20.0/mapbox-gl.js'></script>
<link href='https://api.mapbox.com/mapbox-gl-js/v0.20.0/mapbox-gl.css' rel='stylesheet' />
The NY map code block:
<style>
.mapboxgl-popup {
max-width: 400px;
letter-spacing: 1px;
font: 16px/20px 'Helvetica Neue', Arial, Helvetica, sans-serif;
}
.marker-title {
font-weight: 300;
}
</style>

highlight feature with click in mapbox gl

I have a geojson layer of streets that are highlighted when moused-over.
My objective is now to highlight individual streets red with a click event. Only one street should be able to be highlighted at a time, and should remain highlighted until a different street is clicked.
Any idea as to what needs to be added to the following code?

If you take a look at the console output when running your code, you should see this error message:
layers.street_toggle.paint.line-width:: unknown property "line-width:"
Because of this error, the street_toggle layer is not being added to the map and the click interaction is not working.
To fix the problem, please change the "line-width:" key to "line-width"(remove the spurious colon inside the quotes)

#Lucas features At() must be a depreciated method? His colon did throw a bug, but it doesn't help him select a road segment, at least at v0.16, right? I use queryRenderedFeatures()
note: I really wish this method had a optional radius parameter - you really have to click precisely on the line.
