Issue with Leaflet.js: GeoJSON layer obscured by tilelayer, causing interactivity problems

I am currently working on a leaflet.js project that involves a baselayer, a polygon geojson layer, and another tilelayer positioned above the geojson layer displaying placenames. I have managed to successfully display the placenames tilelayer above the geojson layer by adding it to a map pane. However, this setup has caused click and hover events on the geojson layer to be disabled. I am considering adding the geojson layer to its own pane or possibly the same pane as the placenames tilelayer, but I am unsure of the best approach.

Below is the code I used to add my placenames layer to a pane:

var topPane = map.createPane('leaflet-top-pane', map.getPanes().mapPane);
    topPane.appendChild(CartoDB_PositronOnlyLabels.getContainer());

Here is the CSS code for the pane:

    .leaflet-top-pane {
    pointer-events: none;
}

I have attempted adding my geojson layer to the same pane and adjusting the pointer-events option, but either it does not work or I have yet to find the correct solution. Does anyone have any suggestions on how I can overcome this issue so that the tilelayer overlay appears above the geojson layer while still allowing interaction with the geojson layer?

Answer №1

You might want to consider revising your use of the Leaflet library, such as manually appending a layer to an HTML container or assuming knowledge of the CSS class of the pane.

Try this alternative approach:

map.createPane('labels');    
map.getPane('labels').style.zIndex = 1000;
map.getPane('labels').style.pointerEvents = 'none';

var positron = L.tileLayer('http://{s}.basemaps.cartocdn.com/light_nolabels/{z}/{x}/{y}.png', {
    attribution: '&copy; <a href="http://www.openstreetmap.org/copyright">OpenStreetMap</a> contributors, &copy; <a href="http://cartodb.com/attributions">CartoDB</a>'
}).addTo(map);

var positronLabels = L.tileLayer('http://{s}.basemaps.cartocdn.com/light_only_labels/{z}/{x}/{y}.png', {
    attribution: '&copy; <a href="http://www.openstreetmap.org/copyright">OpenStreetMap</a> contributors, &copy; <a href="http://cartodb.com/attributions">CartoDB</a>',
    pane: 'labels'
}).addTo(map);
