I am trying to find some minamilistic google geocoding script. The ones I have found are very large and complicated, but this one is very simple. The only thing it doesnt do is actually put the co-ordinates in two input boxes like the others.
Here is the code working:
http://jsfiddle.net/Rr5PL/89/
How do I get it to put the co-ordinates in a long / lat input field? It must have them stored because it uses them to display on the map.
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,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
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 {
alert('Geocode was not successful for the following reason: ' + status);
}
});
}
You can simply take them from the Javascript variables. You don't need input fields.
var lat = results[0].geometry.location.lat();
var lon = results[0].geometry.location.lng();
var url = 'www.url.com/search?lon='+lon+'&lat='+lat;
In order to put latitude and longitude in text fields you need to create 2 text boxes first and put latitude and longitude.
var latitude= results[0].geometry.location.lat();
var longitude=results[0].geometry.location.lng();
This jsfiddle shows an example.
http://jsfiddle.net/harendra/njDvn/6/
It's easy, try this
var loc=results[0].geometry.location;
document.getElementById('latLng').value=loc.lat()+', '+loc.lng();

google map marker not showing in bootstrap modal.
this is my jquery code :
function map_init() {
if(!$('body').data('map')){
var var_mapoptions = {
zoom: 6,
mapTypeControl: true,
mapTypeControlOptions: {
style: google.maps.MapTypeControlStyle.DROPDOWN_MENU,
mapTypeIds: ['roadmap', 'terrain']
}
};
$('body').data('map',new google.maps.Map($('<div id="map"/>')[0],
var_mapoptions));
}
return $('body').data('map');
}
var Lat;
var lon;
$(document).on('click','a[data-map]',function(){
var data=$(this).data('map'),
map=map_init();
var geocoder = new google.maps.Geocoder();
var address = data;
geocoder.geocode( { 'address': address}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
var latitude = results[0].geometry.location.lat();
var longitude = results[0].geometry.location.lng();
}
Lat = latitude;
lon = longitude;
});
$('#map_modal')
.find('.modal-body')
.append(map.getDiv())
.end()
.find('.modal-title')
.text(data.Name)
.end()
.one('shown.bs.modal',function(){
google.maps.event.trigger(map, "resize");
map.setCenter({lat:Lat,lng:lon});
});
})
.modal('show');
});
it's showing modal , but not showing the map marker. the latitude and longitude values are came from php code( that is from while loop value).
I believe you did not created any Google Maps Javascript API Markers object.
A marker identifies a location on a map. By default, a marker uses a
standard image. Markers can display custom images, in which case they
are usually referred to as "icons."
I would suggest to edit and add this code inside this line:
if ( status == google.maps.GeocoderStatus.OK ) {
//add marker code here
}
code to be added:
var marker = new google.maps.Marker({
positions : new google.maps.LatLng(results[0].geometry.location.lat(), results[0].geometry.location.lng() ),
map: map,
title: 'I am a marker :)'
});
And your Marker will appear.
I modified the javascript from https://google-developers.appspot.com/maps/documentation/javascript/examples/geocoding-simple to
var geocoder;
var postalArr = [];
postalArr.push(249586);
postalArr.push(266751);
var map;
function initialize(){
var myLatlng = new google.maps.LatLng(1.3667, 103.7500);
var myOptions = {
zoom: 13,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP,
};
if (postalArr) {
for (var i = 0; i < postalArr.length; i++ ) {
codeAddress(postalArr[i]);
}
}
map = new google.maps.Map(document.getElementById('map_canvas'),
myOptions);
}
function codeAddress(postal) {
geocoder.geocode( { 'postal': postal}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
map.setCenter(results[0].geometry.location);
var markerE = new google.maps.Marker({
map: map,
position: results[0].geometry.location,
});
} else {
alert("Geocode was not successful for the following reason: " + status);
}
});
The script goes within the for loop but doesn't run the codeAddress function.
I'm not sure why.
Two things.
(1) need to define geocoder somewhere, I put it in the initialize
function initialize(){
geocoder = new google.maps.Geocoder();
(2) there's no such thing as a postal property to feed the geocoder. Valid requests are for a latlng or an address as explained here.
So at least you must specify a country. I'm not sure what country 249586 is for, in my demo I used two California zip codes, and added ", United States" to the address.
geocoder.geocode( { 'address': postal + ", United States"},
I'm developing a web page with a Google Maps application and there is something that I'm having trouble with. As it stands, the web page has a functional map (without any layers) and a search bar. I'm new to programming so hopefully there is a quick fix that I'm missing.
When I look up an address, the placemark is is positioned where it is supposed to be. However, when I make a second search with a different address, the placemark of the first search remains visible so that there are two placemarks on the screen. How can I make a new placemark replace the old one?
<script type="text/javascript">
var geocoder;
var map;
var marker;
function initialize() {
geocoder = new google.maps.Geocoder ();
var latlng = new google.maps.LatLng (55.1667, -114.4000);
var myOptions = {
zoom: 5,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"),
myOptions);
marker = new google.maps.Marker({map:map});
}
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);
marker.setposition(results [0].geometry.location);
map.setZoom(16);
}
else {
alert("Geocode was not successful for the following reason: " + status);
}
});
}
</script>
One way to achieve what you describe is with a global marker variable. Since the codeAddress function is calling new google.maps.Marker every time it runs, you will get a new marker each time.
Instead, use the setPosition function of the global marker to move it around.
var geocoder;
var map;
// ADDED
var marker;
function initialize() {
geocoder = new google.maps.Geocoder ();
var latlng = new google.maps.LatLng (55.1667, -114.4000);
var myOptions = {
zoom: 5,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"),
myOptions);
// ADDED
marker = new google.maps.Marker({ map: map });
}
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);
// CHANGED
marker.setPosition(results [0].geometry.location);
map.setZoom(16);
}
else {
alert("Geocode was not successful for the following reason: " + status);
}
});
}
I am trying to panTo an area on a map on click. The script is not working and page reloading. Perhaps someone can see the problem.
My function
function clickroute(lati,long) {
map = google.maps.Map(document.getElementById("map_canvas"));
map.panTo(lati,long)
}
And the rest
var directionDisplay;
var directionsService = new google.maps.DirectionsService();
var map;
function initialize() {
geocoder = new google.maps.Geocoder();
directionsDisplay = new google.maps.DirectionsRenderer();
var chicago = new google.maps.LatLng(41.850033, -87.6500523);
var myOptions = {
zoom:10,
mapTypeId: google.maps.MapTypeId.ROADMAP,
center: chicago
}
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
var address = 'virginia water';
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
});
}
});
directionsDisplay.setMap(map);
}
function calcRoute() {
var start = document.getElementById("start").value;
var end = document.getElementById("end").value;
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);
}
});
}
And my event
test
The issue is that your using map.panTo(latitude,longitude) but the google maps API uses this: panTo(latLng myLatLng) where latLng is a google map class.
try something like this (untested)
function clickroute(lati,long) {
var latLng = new google.maps.LatLng(lati, long); //Makes a latlng
map.panTo(latLng); //Make map global
}
Look here for more info.
EDIT
As someone else stated you don't want to remake a new map. Maybe its easier to make it global?
The panTo accepts LatLng object as parameters not just coordinates. Create a LatLng object before passing it to panTo method.
function clickroute(lati,long) {
map.panTo(new google.maps.LatLng(lati,long));
return false; //this will cancel your navigation
}
Your page reloads because you do not cancel the navigation event in onClick that you put in the anchor tag. See comment in code above.
And like the others say take out the map variable from this function and make map global.
you can also set a new marker on the fly:
var LatLng = new google.maps.LatLng(lat, lng);
var marker = new google.maps.Marker({
content: "<h2>Hier wohne ich!</h2>",
map: map,position: results[0].geometry.location
});
map.panTo(LatLng);
You can do this:
var latLng = new google.maps.LatLng(lat_val, lng_value);
map.panTo(latLng);`
The line...
map = google.maps.Map(document.getElementById("map_canvas"));
.. is actually attempting to create a new Map within the #map_canvas Div. Since that map should already exist, you don't need that assignment statement. Just calling
map.panTo(lati,long)
should work?
Edit: Sorry, SSRide360 is correct that should be...
map.panTo(new google.maps.LatLng(lati, long));
Using Google Maps API v3, is there a way to set the center of the map on initialize? I have a workaround using this code:
var geocoder;
var map;
function initialize() {
geocoder = new google.maps.Geocoder();
var latlng = new google.maps.LatLng(-34.397, 150.644);
var myOptions = {
zoom: 8,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
codeAddress('germany');
}
function codeAddress(address) {
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
});
}
});
}
The only problem is that when it initializes, it centers it to the "latlng" for a split second. I'm can't figure out how to set the center in "myOptions". I though I could return "results[0].geometry.location" from the codeAddress function and pass it to myOptions, but that doesn't work.
Thanks for any help.
Update
Since I can't remove "center" altogether, I'm wondering if there's a way to pass the address to the options.
From Google API:
To initialize a Map, we first create a Map options object to contain map initialization variables.
This object is not constructed; instead it is created as an object literal. There are two required
options for every map: center and zoom.
Well a simple solution could be to initialize the map in your codeAddress function:
var geocoder, map;
function codeAddress(address) {
geocoder = new google.maps.Geocoder();
geocoder.geocode({
'address': address
}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
var myOptions = {
zoom: 8,
center: results[0].geometry.location,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
var marker = new google.maps.Marker({
map: map,
position: results[0].geometry.location
});
}
});
}
This should solve the problem.
This is an amazing answer that really helped me get super far. The only issue now is that setCenter is no longer valid in the JavaScript API. Here's my example using fitBounds, ES6 arrow functions to access a this reference to the google map angular component, and finally implementing ngOnChanges to listen for changes to an address text field and re-render the map accordingly.
ngOnChanges(changes: SimpleChanges) {
const newFormattedAddress = changes['formattedAddress']?.currentValue;
if (!newFormattedAddress) {
return;
}
// if we received an update to the formattedAddress from the search box
const geocoder = new google.maps.Geocoder();
geocoder.geocode(
{
address: newFormattedAddress
},
(results: GeocoderResult[], status: GeocoderStatus) => {
if (status === GeocoderStatus.OK && results.length > 0) {
const firstResult = results[0].geometry;
const bounds = new google.maps.LatLngBounds();
if (firstResult.viewport) {
// Only geocodes have viewport.
bounds.union(firstResult.viewport);
} else {
bounds.extend(firstResult.location);
}
this.map.fitBounds(bounds);
}
}
);
}
