I have a Leaflet-map with a layer containing markers with popups using bindPopup. I written this function that flies to the next marker onclick:
const makeFlyTo = () => {
const button = document.getElementById("next");
L.DomEvent.on(button, "click", function(e) {
if (currentView === data.length) {
currentView = 0;
}
map.flyTo(
[data[currentView].lat, data[currentView].lng],
{ zoom },
{
animate: true,
duration: 3
}
);
currentView++;
});
};
I would be nice if the popup opened up on "arrival". Any idea how this can be done?
We have to open marker first and they use FlyTo.
marker.openPopup();
map.flyTo([value['lat'], value['lng']], 15);
As mentioned in the comments, If we use flyTo and then open Popup then most of the times the view adjustment made by popup in map is incorrect.
map.panTo([value['lat'], value['lng']], 15).on('zoomend', () => { setTimeout(()=>marker.openPopup(), 3000) })
OR
map.panTo([value['lat'], value['lng']], 15).on('zoomend', () => marker.openPopup())
Example -
var map = L.map("map").setView([46.76336, -71.32453], 16);
var OpenStreetMap_Mapnik = L.tileLayer(
"http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png",
{
maxZoom: 19,
attribution:
'© OpenStreetMap'
}
).addTo(map);
function addRowTable(marker, code, coords) {
var tr = document.createElement("tr");
var td = document.createElement("td");
td.textContent = code;
tr.appendChild(td);
tr.onclick = () => {
marker.openPopup();
map.flyTo([value['lat'], value['lng']], 15);
};
document.getElementById("t_points").appendChild(tr);
}
function addMarker(code, lat, lng) {
var marker = L.marker([lat, lng]);
marker.title = code;
marker.bindPopup(code);
marker.addTo(map);
addRowTable(marker, code, [lat, lng]);
}
$(document).ready(function () {
var points = [
["M02KM262", 46.76336, -71.32453],
["M10KM052", 46.76186, -71.32247],
["83KM081", 46.76489, -71.32664],
["83KM082", 46.76672, -71.32919]
];
for (var i = 0; i < points.length; i++) {
addMarker(points[i][0], points[i][1], points[i][2]);
}
});

I'm trying to select only one layer using a select.
This is my first time with leaflet and I use this great guide: https://maptimeboston.github.io/leaflet-intro/
Now I have on my map the part of "markerclusters" and the last one "heatmap" and I want to choose only one layer or the other or both.. I've been looking for examples but I don't know how to apply them.
(The select right now is ornamental as you can see.)
And here's the image of my map:

here is my code, thanks in advance!
<html>
<head>
<title>MAPA PRUEBA</title>
<link rel="stylesheet" href="leaflet.css"/>
<link rel="stylesheet" href="MarkerCluster.css"/>
<script src="leaflet.js"></script>
<script src="leaflet.markercluster.js"></script>
<script src="leaflet.heat.js"></script>
<script src="jquery-2.1.1.min.js"></script>
<style>
#map{ height: 100% }
</style>
</head>
<body>
<div id="panel" style = "top-left:10px; background-color:#D3D3D3;">
<label>Tipo de mapa</label>
<select id="estilo" onchange="Bordeaux()">
<option value="points" >PUNTOS</option>
<option value="heat">MAPA DE CALOR</option>
</select>
<div id="map"></div>
<script>
// initialize the map
var map = L.map('map').setView([40.46, -3.74], 4);
// load a tile layer
L.tileLayer('http://192.168.0.103/osm/{z}/{x}/{y}.png',
{
attribution: 'Tiles by MAPC, Data by MassGIS',
maxZoom: 17,
minZoom: 1
}).addTo(map);
// load GeoJSON from an external file
$.getJSON("rodents.geojson",function(data){
var ratIcon = L.icon({
iconUrl: 'images/marker-icon.png'});
var rodents = L.geoJson(data,{
pointToLayer: function(feature,latlng){
var marker = L.marker(latlng,{icon: ratIcon});
marker.bindPopup(feature.properties.Location);
return marker;}
});
var clusters = L.markerClusterGroup();
clusters.addLayer(rodents);
map.addLayer(clusters);
});
// HEAT LAYER
$.getJSON("rodents.geojson",function(data){
var locations = data.features.map(function(rat) {
// the heatmap plugin wants an array of each location
var location = rat.geometry.coordinates.reverse();
location.push(1.9);
return location;
});
var heat = L.heatLayer(locations, { radius: 50 });
map.addLayer(heat);
});
</script>
</body>
</html>
change the clusters and heat variable to global. And add only one of both layers to the map.
var clusters, heat;
$.getJSON("rodents.geojson",function(data){
// ...
clusters = L.markerClusterGroup();
clusters.addLayer(rodents);
map.addLayer(clusters);
});
// HEAT LAYER
$.getJSON("rodents.geojson",function(data){
//...
heat = L.heatLayer(locations, { radius: 50 });
});
Then add / remove the layers in your onchange function from the select:
<select id="estilo" onchange="changeFnc(this)">
<option value="points" >PUNTOS</option>
<option value="heat">MAPA DE CALOR</option>
</select>
function changeFnc(obj){
var value = obj.value;
if(value == "points"){
if(map.hasLayer(clusters)){
map.removeLayer(clusters);
}
map.addLayer(points);
}else{
if(map.hasLayer(points)){
map.removeLayer(points);
}
map.addLayer(clusters);
}
}

my working HTML chart is here
I want to display labels on vAxis as 0%, 5%, 10% up to 20%. So as per Google visualization documentation, I specified vAxis:{format:'#,###%'}
but now it started showing labels like 0%, 500%, 1000%, 1500% and 2000% as you can see in my code above.
Can anyone suggest me the correct way?
the format option assumes the number is already a percent
19.9 = 1,990%
if you want to use the format option,
the values will need to be divided by 100
0.199 = 19.9%
otherwise, you can use custom ticks for the y-axis.
we can provide the value and the formatted value of the tick using object notation.
{v: 20, f: '20%'}
we can also build them dynamically, using data table method --> getColumnRange(colIndex)
// build y-axis ticks
var formatPercent = new google.visualization.NumberFormat({
pattern: '#,##0%'
});
var range = data.getColumnRange(1);
var ticks = [];
for (var i = Math.floor(range.min); i <= Math.ceil(range.max); i = i + 5) {
addTick(i);
}
function addTick(y) {
ticks.push({v: y, f: formatPercent.formatValue(y / 100)});
}
see following working snippet...
google.charts.load('current', {'packages':['corechart', 'controls']});
google.charts.setOnLoadCallback(drawElement3Dashboard);
function drawElement3Dashboard() {
var data = new google.visualization.DataTable();
data.addColumn('string','customer_profile_value');
data.addColumn('number','Current Turnover');
data.addColumn({type:'string', role:'annotation'});
data.addColumn('number','Last year Turnover');
data.addColumn({type:'string', role:'annotation'});
data.addRows([['A+',19.9, '19.9%', 18.2, '18.2%'],['A',5.5, '5.5%', 5.4, '5.4%'],['B',2.4, '2.4%', 2.3, '2.3%'],['C',1.0, '1.0%', 1.0, '1.0%'],['C-',0.3, '0.3%', 0.3, '0.3%']]);
// build y-axis ticks
var formatPercent = new google.visualization.NumberFormat({
pattern: '#,##0%'
});
var range = data.getColumnRange(1);
var ticks = [];
for (var i = Math.floor(range.min); i <= Math.ceil(range.max); i = i + 5) {
addTick(i);
}
function addTick(y) {
ticks.push({v: y, f: formatPercent.formatValue(y / 100)});
}

Hi I have Date picker on select Date Month & Year it will show all Date in that Moth it working Fine

How to fix this issue. I think because of Jquery Conflict Only
How to over come on this??
Hope this helps!
You should use the add method in carousel to append items inside carousel.Also use refresh to run the slider after appending.
owl.trigger('add.owl.carousel', ['<div class="datediv">div-'+i+'<br>'+n+'</div>']).trigger('refresh.owl.carousel');
use remove method to remove items from carousel before appending new items.
for (var i =0; i< $('.owl-item').length; i++) {
owl.trigger('remove.owl.carousel', [i]).trigger('refresh.owl.carousel');
}
$(document).ready(function() {

I am able to get the data from controller and bind it using knockout. There is a partial view that loads data from controller. But when submitting the updated data, I do not get the data that was updated, instead getting error that "FirstName" property could not be accessed from null reference. I just need to get pointers where I am going wrong especially the right way to create ViewModels and use them.
When you are submitting the form in self.SubmitForm function you are passing Json object which is converted from Knockout view model.
So make sure you are providing the data-bind attributes in all input tags properly. If you are using Razor syntax then use data_bind in Html attributes of input tags.
Check 2-way binding of KO is working fine. I can't be sure as you have not shared your partial view Razor code.

In Chrome you can see what data you are submitting in Network tab of javascript developer console. The Json data that you are posting and ViewModel data structure you are expecting in controller method should match.
You can also change the parameters to expect FormCollection formCollection and check what data is coming from browser when you are posting.
