How can i let the "address" locate a current location marker for the user on google map by clicking on the button rather than take the input value
http://jsfiddle.net/razanrab/WppF6/253/
<body>
<div id="panel">
<input id="city_country" type="textbox" value="Berlin, Germany">
<input type="button" value="Geocode" onclick="codeAddress()">

<div id="markerStatus"><i>Click and drag the marker.</i></div>
<b>Current position:</b>
<div id="info"></div>
<b>Closest matching address:</b>
<div id="address"></div>
</div>
</body>
//js
var geocoder;
var map;
var marker;
codeAddress = function () {
geocoder = new google.maps.Geocoder();
var address = document.getElementById('city_country').value;
geocoder.geocode( { 'address': address}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {

Location code is not working here.In fiddle it is working see link below

For some reason my google maps is only loading, after I refresh the page. I already tried a some fixes, but they haven't worked for me.
I already added
$(document).ready(function() {
initMap();
});
$(document).bind("projectLoadComplete", initMap);
to my code, but it doesn't fix the problem.
Some guys also use google.maps.event.addDomListener(window, 'load', initialize); instead of $(document).ready(function() {initMap();}); but then I get the error: "Google is not defined".

Edit: If I open the page with my Map in a new Tab, the map is loading. The error just occurs, if I open the page in the same tab.
Maybe my website doesn't fire the full code of my iFrame.
I fixed the issue. The problem was the window.onmessage = (event) => {.
I think the map couldn't load, because the callback runs before the map receives an onmessage event.
I used the code from another map I created, so I just deleted the onmessage part, because I only need to send some data to my website and not from my website to my html.

I was implementing google maps..And i want the default google blue dot for the current location. can anyone please tell, how to do so, in reactjs or in simple javascript..
First you have to allow the browser to send your Geo location to Google API, then wire up this code on the window/document load event :
var map, infoWindow;
function initMap() {
map = new google.maps.Map(document.getElementById('map'), {
center: { lat: -34.397, lng: 150.644 },
zoom: 6
});
infoWindow = new google.maps.InfoWindow;
// Try HTML5 geolocation.
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function (position) {
var pos = {
lat: position.coords.latitude,
lng: position.coords.longitude
};
infoWindow.setPosition(pos);
infoWindow.setContent('Location found.');
infoWindow.open(map);
var marker = new google.maps.Marker({
position: pos,
map: map,
title: 'Hello World!',
icon: 'https://maps.google.com/mapfiles/kml/shapes/info-i_maps.png',
});
map.setCenter(pos);
}, function () {
//handleLocationError(true, infoWindow, map.getCenter());
});
} else {
// Browser doesn't support Geolocation
//handleLocationError(false, infoWindow, map.getCenter());
}
}
I am trying to recreate the following map, made using Google MyMaps, by using Google Maps API
Anyone know the best way to do this? Have the following code at the moment but doesn't look great
<!DOCTYPE html>

var map;
var infoWindow;
var service;
function initMap() {
map = new google.maps.Map(document.getElementById('map'), {

},
zoom: 10,
styles: [{
stylers: [{
visibility: 'simplified'
}]
}, {
elementType: 'labels',
stylers: [{

}]
}]
});
infoWindow = new google.maps.InfoWindow();
service = new google.maps.places.PlacesService(map);
// The idle event is a debounced event, so we can query & listen without
// throwing too many requests at the server.
map.addListener('idle', performSearch);
}
function performSearch() {
var request = {
bounds: map.getBounds(),
keyword: 'best view'
};
service.radarSearch(request, callback);
}
function callback(results, status) {
if (status !== google.maps.places.PlacesServiceStatus.OK) {
console.error(status);
return;
}
for (var i = 0, result; result = results[i]; i++) {
addMarker(result);
}
}
function addMarker(place) {
var marker = new google.maps.Marker({
map: map,
position: place.geometry.location,

}
});
google.maps.event.addListener(marker, 'click', function() {
service.getDetails(place, function(result, status) {
if (status !== google.maps.places.PlacesServiceStatus.OK) {

use a saved google my maps and share it from your google drive
I am using angular-maps to create a map, with a list of markers.
I have a problem displaying the markers. I have no errors though.
Here is my code:
Controller
var app = angular.module('mapController', []);
app.service('Map', function($q) {
this.init = function() {
var options = {
center: new google.maps.LatLng(45.7154289, 4.9317724),
zoom: 14,
disableDefaultUI: true
}
this.map = new google.maps.Map(
document.getElementById("map"), options
);
this.places = new google.maps.places.PlacesService(this.map);
var markers = [{
"title": 'Capgemini',
"lat": '45.7154289',
"lng": '4.9317724',
"description": 'Capgemini'
}];
var defaultMarkerColor = 'ff0000';
var pinImage = new google.maps.MarkerImage("http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|" + defaultMarkerColor);
// marker object for the marker
var marker = new google.maps.Marker({
position: google.maps.LatLng(markers[0].lat,markers[0].lng),
map: this.map,
title: markers[0].title,
animation: google.maps.Animation.DROP,
icon: pinImage
});
}
this.search = function(str) {
var d = $q.defer();
this.places.textSearch({query: str}, function(results, status) {
if (status == 'OK') {
d.resolve(results[0]);
}
else d.reject(status);
});
return d.promise;
}
this.addMarker = function(res) {
if(this.marker) this.marker.setMap(null);
this.marker = new google.maps.Marker({
map: this.map,
position: res.geometry.location,
animation: google.maps.Animation.DROP
});
this.map.setCenter(res.geometry.location);
}
});
app.controller('mapController', function($scope, Map) {
$scope.place = {};
$scope.search = function() {
$scope.apiError = false;
Map.search($scope.searchPlace)
.then(
function(res) { // success
Map.addMarker(res);
$scope.place.name = res.name;
$scope.place.lat = res.geometry.location.lat();
$scope.place.lng = res.geometry.location.lng();
},
function(status) { // error
$scope.apiError = true;
$scope.apiStatus = status;
}
);
}
$scope.send = function() {
alert($scope.place.name + ' : ' + $scope.place.lat + ', ' + $scope.place.lng);
}
Map.init();
});
and the HTML :
<ion-content ng-controller="mapController" style="margin-top: 25px">
<div class="container">
<div id="map" libraries="places" data-tap-disabled="true"></div>
<form name="searchForm" novalidate
ng-submit="search()">
<div class="input-group">
<input name="place" type="text" class="form-control"
ng-model="searchPlace" required autofocus />
<br>
<span class="input-group-btn">
<button class="btn btn-primary"
ng-disabled="searchForm.$invalid">Search</button>
</span>
</div>
</form>
</div>
The map shows up correctly, and centered on the coordinates I chose, but without a marker.
I would appreciate any help.
Hi took me sometime to put in place the fiddle... :)
I made this changes to make it work:
The markers:
var markers = [{
"title": 'Capgemini',
"lat": 45.7154289,
"lng": 4.9317724,
"description": 'Capgemini'
}];
And then the marker definition
var marker = new google.maps.Marker({
position:{lat: markers[0].lat, lng: markers[0].lng},
map: this.map,
title: markers[0].title,
animation: google.maps.Animation.DROP,
icon: pinImage
});
the easiest way is to use numbers for the coords.
here you can find the fiddle
it isn't super clean and it is lot of debug stuff and most important if you can initialize and see the map you don't really need it.
hope this help
I have this code that allows the user to enter two cities, and shows the location of the given inputs. But what I want is to show as well the direction from the 1st city to the other. How to do that?

Use the DirectionsService in the Google Maps API v3. Here is an example from the documentation:
https://google-developers.appspot.com/maps/documentation/javascript/examples/directions-simple
and with text directions:
https://google-developers.appspot.com/maps/documentation/javascript/examples/directions-panel
if you mean the "location" means the address you can use the direction renderer like below to get the direction.
First of all store the location address of the two markers into the two text boxes if you want to display the to and from address with id's #from and #destination then follow the below code
$("#find").click(function () {
starting = $("#from").val();
finishing = $("#destination").val();
$("#map").gmap3(
{
action: 'getRoute',
options: {
origin: starting,
destination: finishing,
travelMode: google.maps.DirectionsTravelMode.DRIVING
},
callback: function (results) {
if (!results) {
alert("returning")
return
};
$(this).gmap3(
{
action: 'addDirectionsRenderer',
options: {
preserveViewport: true,
draggable: false,
directions: results
}
}
);
}
})
})
Explanation : At first I created two markers of different locations and different data then after the dragend of any marker there will be infowindow that shows the address and two buttons start and finish. I think you have done upto this part .
So after this I used two text boxes which will be filled according to the start button or finish button clicked .
After this if the user clicks the find button this text boxes values are used to find the direction between the two markers
Note: "here you can any marker for from or to only difference you have to maintain is to change the button clicked that is start or finish ....."
"You can even directly give the address in the text boxes and find the directions between them"
Here for whole manipulation I used gmap3 here is the code below that might help you
<script type="text/javascript">
window.onload = clear;
function clear() {
$("#from").val(null)
$("#destination").val(null)
}
$(document).ready(function () {
var starting = "";
var finishing = "";
$("#find").click(function () {
starting = $("#from").val();
finishing = $("#destination").val();
$("#map").gmap3(
{
action: 'getRoute',
options: {
origin: starting,
destination: finishing,
travelMode: google.maps.DirectionsTravelMode.DRIVING
},
callback: function (results) {
if (!results) {
alert("returning")
return
};
$(this).gmap3(
{
action: 'addDirectionsRenderer',
options: {
preserveViewport: true,
draggable: false,
directions: results
}
}
);
}
})
})
$("#map").gmap3({
action: 'addMarkers',
markers: [ //markers array
{lat: 22.74, lng: 83.28, data: 'madhu' },

+ '</div>';
//get address on click event
$(this).gmap3({

var map = $(this).gmap3('get'),

if (infowindow) {

infowindow.open(map, marker);
