I have used the following code to display the marker on the location I have dynamically searched for(code). Now I want to highlight the searched location boundary. (For instance, if I search 'Tokyo', it should mark the boundary of 'Tokyo'(chk the image for reference).
var geocoder;
var map;
function initialize() {
geocoder = new google.maps.Geocoder();
var latlng = new google.maps.LatLng(-34.397, 150.644);
var mapOptions = {
zoom: 8,
center: latlng
}
map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
}
function codeAddress() {
var address = document.getElementById('address').value;
geocoder.geocode({ 'address': address }, function (results, status) {
if (status == google.maps.GeocoderStatus.OK) {
map.setCenter(results[0].geometry.location);
var marker = new google.maps.Marker({
map: map,
position: results[0].geometry.location
});
}
else
{
$('#noResults').html("Unsuccessful:" + status);
}
});
}
google.maps.event.addDomListener(window, 'load', initialize);

How do I make a simple map in Jquery that plots only one location. Here is the code I have now. this plots an array of locations, but I just need a simple map that will plot one point in Lng,Lat format. I am using the google geocoder for this.
var geocoder;
var map;
var markersArray = [];
var bounds;
var infowindow = new google.maps.InfoWindow({
content: ''
});
function initialize() {
geocoder = new google.maps.Geocoder();
bounds = new google.maps.LatLngBounds();
var myOptions = {
zoom: 2,
mapTypeId: google.maps.MapTypeId.ROADMAP,
navigationControlOptions: {
style: google.maps.NavigationControlStyle.SMALL
}
};
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
geocoder.geocode({
'address': '5th Avenus New Yort'
}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
map.setCenter(results[0].geometry.location);
marker = new google.maps.Marker({
map: map,
position: results[0].geometry.location
});
bounds.extend(results[0].geometry.location);
markersArray.push(marker);
} else {
alert("Geocode was not successful for the following reason: " + status);
}
});
plotMarkers();
}
var locationsArray = [
['Google Official', '1600 Amphitheatre Parkway, Mountain View, USA'],
['Google 1', '112 S. Main St., Ann Arbor, USA'],
['Google 2', '10 10th Street NE, Suite 600 USA']
];
function plotMarkers() {
var i;
for (i = 0; i < locationsArray.length; i++) {
codeAddresses(locationsArray[i]);
}
}
function codeAddresses(address) {
geocoder.geocode({
'address': address[1]
}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
marker = new google.maps.Marker({
map: map,
position: results[0].geometry.location
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.setContent(address[0]);
infowindow.open(map, this);
});
bounds.extend(results[0].geometry.location);
markersArray.push(marker);
} else {
alert("Geocode was not successful for the following reason: " + status);
}
map.fitBounds(bounds);
});
}
google.maps.event.addDomListener(window, 'load', initialize);
I then call this in my file with:
<body>
<div id="map_canvas" style="width: 100%; height: 700px;"></div>
</body>
</html>
I need the new map to plot one lat and lng point along with posting the listing the location in the textbook as above. I can not figure out how to do this without an array.
It seems like you're using an example that shows multiple markers.
I haven't tested it, but I think this JavaScript is close:
var geocoder;
var map;
function initialize() {
geocoder = new google.maps.Geocoder();
var latlng = new google.maps.LatLng(-34.397, 150.644);
var mapOptions = {
zoom: 8,
center: latlng
}
map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
geocoder.geocode( { 'address': '5th Avenue New York' }, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
map.setCenter(results[0].geometry.location);
var marker = new google.maps.Marker({
map: map,
position: results[0].geometry.location
});
} else {
alert('Geocode was not successful for the following reason: ' + status);
}
});
}
google.maps.event.addDomListener(window, 'load', initialize);

I was roaming on this site for any info on geocoding a marker. However, I have tried some of the answers but I did not manage to make it work (I am an amateur when it comes to coding), so could someone please help me with the geocoding of my marker? Apparantly, the marker is missing when using this code. I need to geocode postcode in this case, which is the zip code 1058JA. Thanks in advance!
var geocoder;
var map;
var Postcode;
Postcode = '1058JA';
function initialize() {
geocoder = new google.maps.Geocoder();
var latlng = new google.maps.LatLng(52.368465, 4.903921);
var mapOptions = {
zoom: 8,
center: latlng
}
map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
function codeAddress() {
geocoder = new google.maps.Geocoder();
geocoder.geocode( {'address': document.getElementById("address").value },
function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
Postcode = results[0].geometry.location;
map = new google.maps.Map(document.getElementById("map_canvas"),
{
center: Postcode,
zoom: 11,
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var marker=new google.maps.Marker({
position:results[0].geometry.location,
});
marker.setMap(map);
}
else {
document.getElementById("address").value = status;
}
}
);
}
}
google.maps.event.addDomListener(window, 'load', initialize);
There are a few things wrong with your code.
1) codeAddress is never called (as Anto Jurković notes).
2) A new instance of map is created within codeAddress if it were ever called which is redundant.
3) While you've specified Postcode as a string at the top of the code, the geocoder is looking for the value of a input element instead.
Your code should something like this:
var geocoder;
var map;
var Postcode;
Postcode = '1058JA';
function initialize() {
geocoder = new google.maps.Geocoder();
var latlng = new google.maps.LatLng(52.368465, 4.903921);
var mapOptions = {
zoom: 8,
center: latlng
}
map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
codeAddress();
}
function codeAddress() {
geocoder = new google.maps.Geocoder();
geocoder.geocode({'address': Postcode }, function (results, status) {
if (status == google.maps.GeocoderStatus.OK) {
var marker = new google.maps.Marker({
position: results[0].geometry.location,
});
marker.setMap(map);
} else {
document.getElementById("address").value = status;
}
});
}
google.maps.event.addDomListener(window, 'load', initialize);
Demo
i am trying to get address using reverse geocoding.
but there is some problem in geocoder.geocode({...}) line. even normal alert message also not display.
function initialize() {
var mapOptions = {
zoom: 11,
center: new google.maps.LatLng(23.0171240, 72.5330533),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById('map_canvas'),mapOptions);
google.maps.event.addListener(map, 'click', function(e) {
placeMarker(e.latLng, map);
var input=e.latLng;
var lat = parseFloat(input.lat());
var lng = parseFloat(input.lng());
var latlng = new google.maps.LatLng(lat, lng);
geocoder.geocode({'latLng': latlng}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
alert(results[1].formatted_address);
}
});
});
}
function placeMarker(position, map) {
var marker = new google.maps.Marker({
position: position,
map: map
});
map.panTo(position);
}
google.maps.event.addDomListener(window, 'load', initialize);
add below line inside initialize() function.
var geocoder = new google.maps.Geocoder();
My location finder is showing multiple markers, but i don't want that.
I'm not that good with the Google API, so i hope you can help me.
People need to fill in their address, and then he need to show the location. Without showing multiple markers. (only one)
Here is the JS:
var geocoder;
var map;
function initialize() {
geocoder = new google.maps.Geocoder();
var latlng = new google.maps.LatLng(52.132633, 5.291266);
var myOptions = {
zoom: 7,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map_canvas"),
myOptions);
}
function codeAddress() {
var sAddress = document.getElementById("inputTextAddress").value;
document.getElementById("map_canvas").style.removeProperty('display');
geocoder.geocode( { 'address': sAddress}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
map.setCenter(results[0].geometry.location);
map.setZoom(10);
var marker = new google.maps.Marker({
map: map,
position: results[0].geometry.location
});
} else {
alert("Helaas, er is iets fout gegaan. Foutcode: " + status);
}
});
}
If you want to have control of your markers, you need to add them into an array and then remove all of them before adding a new one:
markersArray = []
function codeAddress() {
var sAddress = document.getElementById("inputTextAddress").value;
document.getElementById("map_canvas").style.removeProperty('display');
geocoder.geocode( { 'address': sAddress}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
map.setCenter(results[0].geometry.location);
map.setZoom(10);
var marker = new google.maps.Marker({
map: map,
position: results[0].geometry.location
});
RemoveMarkers();
markersArray.push(marker)
} else {
alert("Helaas, er is iets fout gegaan. Foutcode: " + status);
}
});
}
function RemoveMarkers(){
for(i=0;i<markersArray.length;i++){
markersArray[i].remove() // I don't remember exactly the name of the gmaps method
}
}
I haven't tested the code, but this is the idea you need!
I'm trying to accomplish the following with the Google Maps API:
Display to_address as a marker on the map
Get users location
Generate and display directions based on the information given by gps/user input
I have gotten the last two to work just fine. The problem I am having now is showing the to_address as a marker on the map if the location is not provided.
This is the code I am using. Keep in mind the last 2 steps work as expected. I know that I can accomplish this using latlng but that is not an option for me. I need to provide it an address.
var geocoder;
var directionDisplay;
var directionsService = new google.maps.DirectionsService();
var to_pos;
var to_address = '11161 84th ave delta bc';
function initialize() {
directionsDisplay = new google.maps.DirectionsRenderer();
geocoder = new google.maps.Geocoder();
geocoder.geocode({
'address': to_address
}, function (results, status) {
if (status == google.maps.GeocoderStatus.OK) {
to_pos = results[0].geometry.location;
}
});
var myOptions = {
zoom: 7,
mapTypeId: google.maps.MapTypeId.ROADMAP,
center: to_pos
};
var map = new google.maps.Map(document.getElementById('map_canvas'), myOptions);
directionsDisplay.setMap(map);
directionsDisplay.setPanel(document.getElementById('directions'));
var control = document.getElementById('d_options');
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function (position) {
var pos = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
var infowindow = new google.maps.Marker({
position: pos,
map: map,
title: "You"
});
map.setCenter(pos);
$('#from').val(pos);
$('#d_options').trigger('collapse');
calcRoute();
}, function () {
handleNoGeolocation(true);
});
}
}
function calcRoute() {
var start = document.getElementById('from').value;
var end = to_address;
$('#results').show();
var request = {
origin: start,
destination: end,
travelMode: google.maps.DirectionsTravelMode.DRIVING
};
directionsService.route(request, function (response, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
}
});
}
google.maps.event.addDomListener(window, 'load', initialize);
geocoding uses an asynchronous request. You must create the marker inside the callback of geocode()
geocoder.geocode({
'address': to_address
}, function (results, status) {
if (status == google.maps.GeocoderStatus.OK) {
var to_pos = results[0].geometry.location;
new google.maps.Marker({
position: new google.maps.LatLng(to_pos.lat(),to_pos.lng()),
map: map,
title: "Destination"
});
}
});
