Mapbox problem with creating PopUp for each cluster/marker with dynamic data

I have a problem where I am fetching my data from my API using WordPress. I have multiple clusters/markers on my map. But I am not able to create for each location a PopUp marker with the data coming from the API. I am facing some scoping issue where I want to have one popup dynamically show the data based ont he clicked marker if that makes sense.
Is there a trick on how to solve this?

Layer in Leaflet JS doesnt show again when check the control layer

I use the leaflet control layer to show up and remove the layer when I didn't wanna show the layer. when I uncheck my control layer it worked properly. the layer can disappear, but when I check again the control layer, the layer didn't show again. but there is no error in the console .
var pieChartGroup = L.featureGroup().addTo(map);
vals.forEach(val => {
var pictures = L.marker(val.location, {
icon: L.divIcon({
className: 'leaflet-echart-icon',
iconSize: [160, 160],
html: '<div id="marker' + val.id + '" style="width: 160px; height: 160px; position: relative; background-color: transparent;"></div>'
})
}).addTo(pieChartGroup);
// Based on the prepared dom, initialize the echarts instance
var myChart = echarts.init(document.getElementById('marker' + val.id));
// Specify chart configuration items and data

tooltip: {
trigger: 'item',

context menu Items in leaflet

I'm making a map using the Neshan platform.
I want to show context menu of a marker،
I have written this code but it's not displaying the context menu
myMap.on('click', function (e) {
marker = new L.Marker(e.latlng, {
contextmenu: true,
contextmenuItems: [
{
text: 'Marker item',
index: 0
},
{
separator: true,
index: 1
}
]
}).addTo(myMap);
});

displaying bar chart on the bottom of html page fails

I am trying to load geojson data, which I hard coded as variable called sample. Now I want to display a chart after clicking on each feature. Below is my code. But it gives the ErrorMessage: feature is undefined.
var map = L.map('map').setView([55, 3], 5);
L.tileLayer( 'http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
attribution: '© OpenStreetMap',
subdomains: ['a','b','c']
}).addTo( map );
var trees = L.geoJson(Sample).addTo(map);
trees.on('click', function ( evt) {
feature = evt.layer.feature;
$("#chart").empty();
var chart = c3.generate({
data: {
names: {
data1: 'a',
data2: 'b',
data3: 'c',
data4: 'd',
data5: 'e'
},
// just taken some RANDOM fields to demonstrate
// how to draw the chart
columns: [
['data1',
feature.properties.a],
['data2',
feature.properties.b],
['data3',
feature.properties.c],
['data4',
feature.properties.d],
['data5',
feature.properties.e]
],
types: {
data1: 'bar',
data2: 'bar',
data3: 'bar',
data4: 'bar',
data5: 'bar'
}
},
axis: {
rotated: false,
x: {
label: {
text: 'Your Topics',
position: 'outer-middle'
}
},
y: {
label: {
text: 'Your_Values',
position: 'outer-center'
}
}
}
});
});

The event layer in the trees click handler doesn't have features. You should add the click handler to each layer:
var trees = L.geoJson(Sample, {
onEachFeature: function onEachFeature(feature, layer) {
layer.on('clicked feature', function(evt) {
console.log('feature=', feature);
$("#chart").empty();
// generate chart here using feature
// var chart = c3.generate({...});
});
}
}).addTo(map);

Sencha Touch 2 Map using different Latitude and Longitude for each item in List (Sencah)

I am building an app which contains a list of addresses. This app is working in such a way that once the user clicks on each of the items (addresses) in the list, the next page shows a map, and the map has a marker which points to the exact location of the address clicked on. This is made possible due to the Latitude and Longitude coordinates stated in code.
My problem is that I have more than one address, and each of these addresses have a unique longitude and latitude. I want to make my app work in such a way that when a user clicks on any address they are interested in, the app will open a page and show the map and a marker pointing to the exact location of the address on the map. My code's below: it is working perfectly, BUT when the user clicks on the address, it takes them to the same logitude and latitude.
My store:
Ext.define('List.store.Presidents', {
extend : 'Ext.data.Store',
config : {
model : 'List.model.President',
sorters : 'lastName',
grouper : function(record) {
return record.get('lastName')[0];
},
data : [{
firstName : "Ikhlas HQ",
lastName : "Tower 11A, Avenue 5, Bangsar South, No.8 Jalan Kerinchi 59200 Kuala Lumpur",
latitude : 3.110649,
longitude : 101.664991,
id: 'm12',
},
{
firstName : "PEJABAT WILAYAH SELANGOR",
lastName : "No. 97, 97-1 & 97-2, Jalan Mahogani 5/KS7, Ambang Botanic, 41200 Klang, Selangor",
latitude : 3.003384,
longitude : 101.45256,
id: 'm1',
}, ]
}
});
My controller:
Ext.define('List.controller.Main', {
extend: 'Ext.app.Controller',
config: {
control: {
'presidentlist': {
disclose: 'showDetail'
},
}
},
showDetail: function(list, record) {
this.getMain().push({
xtype: 'presidentdetail',
title: record.fullName(),
listeners: {
maprender: function(comp, map) {
var position = new google.maps.LatLng(5.978132,116.072617);
var marker = new google.maps.Marker({
position: position,
map: map
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map, marker);
});
setTimeout(function() {
map.panTo(position);
}, 1000);
},
},
})
},
});
My view:
Ext.define('List.view.PresidentDetail', {
extend : 'Ext.Map',
xtype: 'presidentdetail',
config: {
title: 'Details',
styleHtmlContent: true,
scrollable: 'vertical',
//useCurrentLocation: true,
layout: 'fit',
mapOptions: {
zoom: 16,
mapTypeId: google.maps.MapTypeId.ROADMAP,
navigationControl: true,
navigationControlOptions: {
style: google.maps.NavigationControlStyle.DEFAULT
}
},
}
});
My model:
Ext.define('List.model.President', {
extend : 'Ext.data.Model',
config : {
fields : ['firstName', 'middleInitial', 'lastName', 'latitude', 'longitude']
},
fullName : function() {
var d = this.data, names = [d.firstName, (!d.middleInitial ? "" : d.middleInitial + "."), d.lastName];
return names.join(" ");
}
});
Help me out please. I need each of the addresses on the list to be tagged with a latitude and longitude so that when the user clicks on the address, it will point to the exact location the map.

Your line:
var position = new google.maps.LatLng(5.978132,116.072617);
Is fixed to the same coordinates so it will never change.
In my application I have the view fire an event to the controller and then in the controller have a reference to the record's coordinates which are then set to the map.
In view:
config: {
layout: 'fit',
items: [
{
xtype: 'map',
listeners: {
maprender: function (extMapComponent, googleMapComp) {
this.fireEvent('googleMapRender', googleMapComp);
}
}
}
]
}
Controller:
refs: {
mapRef: 'map'
},
Control: {
mapRef: {
googleMapRender: 'onGoogleMapRender'
}
}
onGoogleMapRender: function (googleMap) {
// this.selectedRecord should be set when you select the item in the list
// so that you can pull the coordinates off
var record = this.selectedRecord;
var long = record.get("Longitude");
var lat = record.get("Latitude");
var marker = new google.maps.Marker({
position: new google.maps.LatLng(lat, long);
});
marker.setMap(googleMap);
}
