I'm working on a map with mapbox, also it has a list of locations per countries, states and cities, and when I am clicking one of them, their location should be shown.
So I´m adding the geocoder L.mapbox.geocoder of mapbox but the coordinates of some places are not precise enough e.g. US or France.
How can I solve this?
I also thought to use google's geocoding service Google Geocoder.
How could I do this ?
Example code
I hope you can help me.
If you are going to use mapbox, there is no guarantee for accurate data over the whole world, because mapbox streets is based on a volunteered database called OpenStreetMap: "Data for Mapbox Streets comes primarily from OpenStreetMap, with Natural Earth and our own tweaks used for some parts" [source]. So if you have to be more accurate the google Geocoder should be the API of your choice. The pricing depends on the requests per day.
Here is an google Geocoding example:

You'll need your own API key so make sure you go through Google's get started guide to properly set up your project and billing account.
Hope this helps!

Thank you I hope someone could help been having this problem alot
This error indicates on a missing Google Maps API key.
https://developers.google.com/maps/documentation/javascript/get-api-key
Click the button below, to get an API key using the Google Cloud Platform Console. You will be asked to (1) pick one or more products, (2) select or create a project, and (3) set up a billing account. Once your API key is created you will be prompted to restrict the key's usage. For more information, see Restricting an API key.
(Button is present in the link)
When loading the Maps JavaScript API, substitute YOUR_API_KEY in the
code below with the API key you got from the previous step.
<script async defer src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap" type="text/javascript"></script>
If you follow the steps beyond the link, that should fix the error you're getting.
I want to put a loading icon before finding or I need catch find location start/end function (like ajax before/success function)
I could not find any resources related to this .I want to do; When you click on the "Find current location" button, you will see a small icon. Hide the icon when the process is finished
I use javascript without jquery

this is my first post here so I apologize if I make a newbie faux pas.
I've got a Google Fusion Table layer that I have on top of a map. I created it by importing a KML file. Everything works great, but last week I realized that the InfoWindow is now displaying all of the vertices of the relevant polygon in the geometry field.
The strange thing is that these vertices do not display in the actual Fusion Table but only on the layer on top of the map. I suspect something might be going on with the JavaScript code, which I am very new to, or perhaps the new API for the Fusion Tables.
I removed the body section to get around some formatting issues on this page, but here is the code:

Can anyone shed some light on this?

You can configure the content shown in the infowindow.
See this page in the Fusion Tables Help
You must define the templateId to have the same content for the infoWindow.
Add this to the options passed to the layer:
templateId:2
I ended up changing the code to reference another Fusion Tables Layer. All I changed was the ID. This seems to work with the new layer, but I still do not know what happened to display the geometry in the InfoWindow.
If it happens again, I will most likley attempt Dr.Molle's suggestion.
I'm in a spot of bother and my hairline is on the chopping block. When I integrated the maps API on this site, ritaknoetze.com, everything worked perfectly.
However, copying that exact code for a different demo website, scarabpaper, the map doesn't show up at all? Could someone show me the ropes on what I'm doing wrong?
Here's the code I got from Google itself that I modified for my WordPress theme/installation:
JavaScript:
<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script type="text/javascript">
function initialize() {
var myLatlng = new google.maps.LatLng(-34.009839, 22.78101);
var myOptions = {
zoom: 9,
center: myLatlng,
navigationControl: true,
mapTypeControl: false,
scaleControl: false,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
var image = '<?php bloginfo('template_url')?>/assets/googlemaps_marker.png';
var myLatLng = new google.maps.LatLng(-34.009839, 22.78101);
var beachMarker = new google.maps.Marker({
position: myLatLng,
map: map,
icon: image
});
}
</script>
My HTML where the javascript goes:
<div class="contact_container">
<div id="map_canvas"></div>
<div class="clearfloat"></div>
</div>
My CSS for the affected divs
#map_canvas {
width: 880px;
height: 300px;
margin-left: 10px;
margin-bottom: 30px;
margin-top: 10px;
float: left;
border: 1px solid #dedcdc;}
.contact_container { /*container for ALL the contact info*/
background-color: #fff;
border: 1px solid #dedcdc;
width: 900px;
margin-top: 30px;
padding: 20px;
padding-bottom: 0;}
Any Help would be greatly appreciated...
You're never calling the initialize() method. It works if you call that method, even using a console.
