Having a problem with leaflet routing machine. The very basic code
var routingtest = L.Routing.control({
waypoints: [
L.latLng(57.74, 11.94),
L.latLng(57.6792, 11.949)
]
}).addTo(mymap);
does run fine.
But as soon as I add more code like described at http://www.liedman.net/leaflet-routing-machine/tutorials/ I get errors.
For example this does not work:
var routingtest = L.Routing.control({
waypoints: [
L.latLng(57.74, 11.94),
L.latLng(57.6792, 11.949)
],
routeWhileDragging: true,
geocoder: L.Control.Geocoder.nominatim()
}).addTo(mymap);
It throws back TypeError: L.Control.Geocoder is undefined.
I just redownloaded the plugin to make sure nothing has been accidentially modified, but still.
My index.html looks like this:

My leaflet map var with one of the basemaps looks like this:
var mymap = L.map('map', {
center: [57.89, 12.02],
zoom: 13.5,
fullscreenControl: true
});
var osm = L.tileLayer('http://{s}.tile.osm.org/{z}/{x}/{y}.png',
{ attribution: '© OpenStreetMap'
}).addTo(mymap);
What could cause the TypeError: L.Control.Geocoder is undefined error and how to fix it?
I installed https://github.com/perliedman/leaflet-control-geocoder plugin and now it works. Its stated nowhere that this is a prerequisiste though...

The problem I am having is that the map is not showing up at all, there is a blank spot where the map is meant to be. I have followed Leaflet's quick-start guide and I still have yet to determine why my map does not show.
Below is the code I have so far:

You import the Leaflet JavaScript file and have your page code within the same HTML <script> tag. In such case, browsers are supposed to ignore (not execute) the content between the script tags, i.e. your page code is not executed.
Simply separate in 2 different script tag pairs:
<script src="https://unpkg.com/leaflet#1.7.1/dist/leaflet.js"></script>
<script>
var mymap = L.map('mapid').setView([51.505, -0.09], 13);
// etc.
</script>
I'm using leaflet v1.5.1.
The error from Chrome is:
leaflet.js:5 Uncaught TypeError: this.callInitHooks is not a function
at Object.i [as Marker] (leaflet.js:5)
at map1Rose2.php:77
Below is the minimal code that will reproduce the issue in Chrome. I do NOT see an issue with the function. The error appears at the first 'var' (line 77) in the .
I've prodded and poked at this thing to exhaustion does anyone have an idea?

You have to call new L.Marker() or L.marker()
To fix your second error (in the comments) you have to define first your featureGroup and then create the markers.
var fg = new L.featureGroup();
var WA0TJT = L.Marker(new L.LatLng(39.202911,-94.602887),{
contextmenu: true,
contextmenuWidth: 140,
contextmenuItems: [{ text: 'Click here to add mileage circles', callback: circleKoords}],
icon: new L.NumberedDivIcon({number: '1' }),
title:"marker_1" }).addTo(fg).bindPopup("1<br><b>ID: #0013</b><br>WA0TJT<br>Keith Kaiser<br>Platte Co., MO Dist: A<br>39.202911, -94.602887<br>EM29QE").openPopup();
also you will nothing see on the map, because you are not added your featuregroup to the map. And you need a map instance.
var map = L.map('map', {
...
});
fg.addTo(map);
i'm new in html and leaflet, i don't know how to use plugins in leaflet
right now i'm working with polyline decorator plugins but i don't know how to use it right
i'm trying following tutorial on internet, here my code
var arrow = L.polyline([[107.63576,-2.72322], [107.65699,-2.7366]], {}).addTo(map);
var arrowHead = L.polylineDecorator(arrow, {
patterns: [
{offset: '100%', repeat: 0, symbol: L.Symbol.arrowHead({pixelSize: 15, polygon: false, pathOptions: {stroke: true}})}
]
}).addTo(map);
and here my head section

You have the latitudes and longitudes swapped in the call to L.polyline. Try this line instead:
var arrow = L.polyline([[-2.72322, 107.63576], [-2.7366, 107.65699]], {}).addTo(mymap);
I am using d3.geomap in Grails to create a map of the US.
As said in https://d3-geomap.github.io/ my gsp look like:
<html>
<head>
<meta name="layout" content="main" charset="utf-8">
<link rel="stylesheet" href="${resource(dir: 'css', file: 'd3.geomap.css')}" type="text/css">
<g:javascript src="d3.geomap.dependencies.min.js" />
<g:javascript src="d3.geomap.min.js" />
</head>
<body>
<script>
var map = d3.geomap.choropleth()
.geofile('/topojson/countries/USA.json')
.projection(d3.geo.albersUsa)
.column('2012')
.unitId('fips')
.scale(1000)
.legend(true);
d3.csv("mapusa", function(error, data) {
d3.select('#map')
.datum(data)
.call(map.draw, map);
});
</script>
<div id="map"></div>
</body>
</html>
The css file d3.geomap.css is under web-app/css.
The js files d3.geomap.dependencies.min.js and d3.geomap.min.js are under web-app/js.
Under grails-app/views/ I have the topojson folder.
When I run the page it gives me:
Uncaught TypeError: Cannot read property 'choropleth' of undefined
d3.geomap is undefined.
Any ideas?
Thanks in advance.
In my main.gsp I have:
<script src="http://d3js.org/d3.v3.min.js"></script>
When I remove this, then d3.geomap has value and show the US map. I am not sure why they enter in conflict.
Try this code below, you will get your desired output of world map. Similarly, you can do it for US maps.

Add the following line to the <head> section of your page, before the section that you've pasted above:
<script src="http://ecn.dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=7.0" type="text/javascript"

Have you included the include for the maps api?
<script type="text/javascript" src="bingmaps.js"></script>
Or are you using the rest service, in which case you need to specify the location of the service in an AJAX call...
