How to display two text fields into one - javascript

I have this code of google map with coordinates values
the questions is how we can merge the text field of Lat & Lon into one field only,
so we need one text field only display the coordinated (Lat,Lon)
can any one help
the code is below

Try this code:
function update() {
var lonlan = marker.getPosition();
var divLat = document.getElementById ("divLat");
divLat.value = lonlan.lat ()+", "+lonlan.lng ();
}

Simplest solution, use the .toUrlValue method of a google.maps.LatLng
function update() {
var lonlan = marker.getPosition();
var divLatLon = document.getElementById("divLatLon");
divLatLon.value = lonlan.toUrlValue(6);
}
code snippet:
var marker;
function initialize() {
var lat;
var lon;
navigator.geolocation.getCurrentPosition(function(location) {
lat = location.coords.latitude;
lon = location.coords.longitude;
var city = new google.maps.LatLng(lat, lon);
var mapOptions = {
zoom: 15,
center: city,
mapTypeId: google.maps.MapTypeId.HYBRID
};
var map = new google.maps.Map(document.getElementById

var image = "icon.png";
marker = new google.maps.Marker({

google.maps.event.addDomListener(window, "load", initialize);
function update() {

trouble getting my mouseover on markers to work

I have created my code below with the mouseover affect at the end, but it does not work. Have I put it in the wrong place? I just can't seem to get it to work. Eventually I would like to get a certain type of info displayed on them but each step at a time, trying to get the basic to work first.

You need to:
define contentString
associate the marker with the infowindow content. One way of doing that is with anonymous function closure as in this related question Google Maps JS API v3 - Simple Multiple Marker Example, or with an explicit createMarker function as in my example below.
Note: This approach will only work for approximately 10 addresses, after which it will run into the Geocoder rate limits.
function createMarker(latlng, html, map) {
var infowindow = new google.maps.InfoWindow({
content: html
});
var marker = new google.maps.Marker({
map: map,
position: latlng
});
marker.addListener('mouseover', function() {
infowindow.open(map, this);
});
marker.addListener('mouseout', function() {
infowindow.close();
});
}

google api reverse geocode

I Have a google map on my site. Users can drag the marker and the map will input the lat and lon into a form for me. See code below. I want to be able to get the address from the lat and lon and put it into my form at "locationbox".
<script src="multi_step_form.js"></script>
<script src="https://maps.googleapis.com/maps/api/js?callback=initMap" async defer></script>
<script type="text/javascript">
var map;
function initialize() {
var myLatlng = new google.maps.LatLng(49.25302534866034,-102.04825518471148);
var myOptions = {
zoom: 3,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.HYBRID
}
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
var marker = new google.maps.Marker({
draggable: true,
position: myLatlng,
map: map,
title: "Your location"
});
google.maps.event.addListener(marker, 'dragend', function (event) {
document.getElementById("latbox").value = this.getPosition().lat();
document.getElementById("lngbox").value = this.getPosition().lng();
});
}
</script>
I have another bit of code to look up the address that I got from https://203luv.wordpress.com/2011/10/21/google-maps-javascript-v3-api-how-to-get-address-from-coordinates-latitude-longitude/ but I just can't figure out how to blend them together.
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script type="text/javascript">
var geocoder = new google.maps.Geocoder();
var lat = "12.1234";
var long = "98.7654";
var latlng = new google.maps.LatLng(sLat, sLong);
geocoder.geocode({"latLng":latlng},function(data,status){
if(status == google.maps.GeocoderStatus.OK){
var add = data[1].formatted_address; //this is the full address
alert(add);
for(var i=0; i<data[1].address_components.length; i++){
if(results[1].address_components[i].types[0] == "administrative_area_level_1"){
alert(results[1].address_components[i].short_name);
}
}
}
})
My html form looks like this
<div id="map_canvas" style="width: 450px; height: 450px; background-color: Black;"></div>
<div id="latlong">
<p><input size="20" type="text" id="latbox" name="lat" placeholder="Drag the marker on the map or type in the latitude"></p>
<p><input size="20" type="text" id="lngbox" name="lon" placeholder="Drag the marker on the map or type in the longitude"></p>
</div>
<input class="text_field" id="locationbox" name="location" placeholder="Location" type="text" >
Any help would be appreciated
I would suggest calling the reverse geocoder in the dragend event listener function:
google.maps.event.addListener(marker, 'dragend', function (event) {
document.getElementById("latbox").value = this.getPosition().lat();
document.getElementById("lngbox").value = this.getPosition().lng();
var latlng = this.getPosition();
geocoder.geocode({
"latLng": latlng
}, function (data, status) {
if (status == google.maps.GeocoderStatus.OK) {
var add = data[1].formatted_address; //this is the full address
// alert(add);
for (var i = 0; i < data[1].address_components.length; i++) {
if (data[1].address_components[i].types[0] == "administrative_area_level_1") {
document.getElementById('locationbox').value = data[1].address_components[i].short_name;
}
}
}
});
});

Loading Google maps marker on button click using geolocation

My code should define the geolocation of the user and assign it the value pos. I then want to use this value of pos to create a marker upon a button click.
However, I do not get a point being plotted. Both position and map are global variables that have already been assigned, so can't figure out why I am not getting a response.
Any help would be much appreciated!

Add your "click" listener function inside the initialize function. That runs when the onload event fires and the DOM has been rendered. Before that the button can't be found in the DOM.

Google map is not zooming in & marker is not showing on page load

I am facing issue with Google map. It is not properly displaying with marker on page load. It appears to display properly with marker when we zoom in on displayed map.
Any help appreciated.
This is javascript code :-
var GoogleMap = function(canvas, address)
{
var _parent = this;
this.location = new google.maps.LatLng(-34.397, 150.644);
var options =
{
center: this.location,
zoom: 15,
mapTypeId: google.maps.MapTypeId.ROADMAP,
mapTypeControlOptions:
{
style: google.maps.MapTypeControlStyle.HORIZONTAL_BAR,
position: google.maps.ControlPosition.TOP_CENTER
},
streetViewControl: false
};
this.map = new google.maps.Map(canvas, options);
var geocoder = new google.maps.Geocoder();
geocoder.geocode( { 'address': address}, function(results, status)
{
if (status != google.maps.GeocoderStatus.OK)
return;
_parent.location = results[0].geometry.location;
var marker = new google.maps.Marker(
{
map: _parent.map,
position: _parent.location
});
_parent.resize();
});
};
GoogleMap.prototype.resize = function()
{
google.maps.event.trigger(this.map, "resize");
this.map.setCenter(this.location);
}
var Maps = function(classes)
{
var _parent = this;
_parent.maps = new Array();
classes.each(function()
{
_parent.maps.push(new GoogleMap($(this).get(0), $(this).attr("data-address")));
});
};
Maps.prototype.resize = function()
{
for (var cnt = 0; cnt < this.maps.length; cnt++)
{
this.maps[cnt].resize();
}
};
var maps;
$(window).load(function()
{
maps = new Maps($(".gMapsCanvas"));
});
This is HTML code :-
<div class="gMapsCanvas" data-address="Address,City,State,Country"></div>
It's working fine to me.
What address did you provide. Do you have errors in the console?
Copy this exemple in a plain .html file and you will see it works. Then figure out what is different in your entire page:
<!DOCTYPE html>
<html>
<head>
<title>Getting Zoom Demo</title>
<style type="text/css">
html, body{ height: 100%; height: 100%; margin: 0; padding: 0; }
.gMapsCanvas{ height: 100%; width: 100%; min-width:500px; min-height:300px; }
</style>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script>
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false"></script>
</head>
<body>
<div>
<label id="display-zoom-label">
</label>
</div>
<div class="gMapsCanvas" data-address="3209 West Smith Valley Road, Greenwood, IN"></div>
<script>
var GoogleMap = function (canvas, address) {
var _parent = this;
this.location = new google.maps.LatLng(-34.397, 150.644);
var options =
{
center: this.location,
zoom: 15,
mapTypeId: google.maps.MapTypeId.ROADMAP,
mapTypeControlOptions:
{
style: google.maps.MapTypeControlStyle.HORIZONTAL_BAR,
position: google.maps.ControlPosition.TOP_CENTER
},
streetViewControl: false
};
this.map = new google.maps.Map(canvas, options);
var geocoder = new google.maps.Geocoder();
geocoder.geocode({ 'address': address }, function (results, status) {
if (status != google.maps.GeocoderStatus.OK)
return;
_parent.location = results[0].geometry.location;
var marker = new google.maps.Marker(
{
map: _parent.map,
position: _parent.location
});
_parent.resize();
});
};
GoogleMap.prototype.resize = function () {
google.maps.event.trigger(this.map, "resize");
this.map.setCenter(this.location);
}
var Maps = function (classes) {
var _parent = this;
_parent.maps = new Array();
classes.each(function () {
_parent.maps.push(new GoogleMap($(this).get(0), $(this).attr("data-address")));
});
};
Maps.prototype.resize = function () {
for (var cnt = 0; cnt < this.maps.length; cnt++) {
this.maps[cnt].resize();
}
};
var maps;
$(window).load(function () {
maps = new Maps($(".gMapsCanvas"));
});
</script>
</body>
