I have a .js file with coordinates for internships:
var internships = [{
"features": [
{"type":"Feature","properties":{"category":"entretient","Name":"green"},"geometry":{"type":"Point","coordinates":[50.807149, 3.162994]}},
{"type":"Feature","properties":{"category":"securité","Name":"blue"},"geometry":{"type":"Point","coordinates":[50.334421, 3.290146]}},
{"type":"Feature","properties":{"category":"secretaria","Name":"red"},"geometry":{"type":"Point","coordinates":[50.744787, 2.256216]}}
]
}];
I've found this bit of code allowing me to create layers depending on a property and here what my JS looks like:
$.getScript("CoordinatesPdC.js");
function mapLoad() {
var sécuritéLayer = new L.LayerGroup();
var secrétariatLayer = new L.LayerGroup();
var entretientLayer = new L.LayerGroup();
var map = L.map('map').setView([50.2910, 2.7775], 8);
L.tileLayer('http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
maxZoom: 18,

'<a href="https://creativecommons.org/licenses/by-sa/2.0/">CC-BY-SA</a>, '
}).addTo(map);
var marker = L.marker([50.2910, 2.7775]).addTo(map);
var entretientLayer = L.geoJson(internships, {
filter: function (feature, layer) {
return (feature.properties.category === "entretient");
}
}).addTo(map);
var sécuritéLayer = L.geoJson(internships, {
filter: function (feature, layer) {
return (feature.properties.category === "sécurité");
}
}).addTo(map);
var secrétariatLayer = L.geoJson(internships, {
filter: function (feature, layer) {
return (feature.properties.category === "secrétariat");
}
}).addTo(map);
}
window.onload = mapLoad;
But now I have to create the markes assigned to these layers, how can I achieve that?

You're missing the pointToLayer function. Also I checked your GeoJSON and it didn't meet the GeoJSON specs. Look at geojsonlint.com and geojson.io part of it was a data issue

I don't need to make a specific marker for each category because I'm going to make them toggeable however I changed my 'var secrétariatLayer' to yours but but the marker doesn't show up

You also had grouplayers but never put the data into the grouplayer. You declared the variables as group layer then re-declared them as layers. You would do something like myGroupLayer.addLayer(myLayer); myGroupLayer.addTo(map);
– Bill Chappell
Aug 10 '18 at 13:55
thank for your help, however how do I apply it for the other coordinates? Do I duplicate the filter for each category possible?
– Victor Lernout
Aug 10 '18 at 18:15
I edited the code to show my layer block, for three layers you should have three copies. You only need to change the layer name for all three layers and the filter condition. If it was 10 layers I might make a function but for three it's easier to duplicate the code.
– Bill Chappell

Sorry to disturb you but your help is really helpful, in case I'll have more categories, and since you're talking about it, how should I make the function?

I don't need to make a specific marker for each category because I'm going to make them toggeable however I changed my 'var secrétariatLayer' to yours but but the marker doesn't show up

You also had grouplayers but never put the data into the grouplayer. You declared the variables as group layer then re-declared them as layers. You would do something like myGroupLayer.addLayer(myLayer); myGroupLayer.addTo(map);

thank for your help, however how do I apply it for the other coordinates? Do I duplicate the filter for each category possible?

I edited the code to show my layer block, for three layers you should have three copies. You only need to change the layer name for all three layers and the filter condition. If it was 10 layers I might make a function but for three it's easier to duplicate the code.

Sorry to disturb you but your help is really helpful, in case I'll have more categories, and since you're talking about it, how should I make the function?
