I spent a lot of time to solve this, and can't figure it how to work, so here is my base:
<script>
function initialize() {
var mapOptions = {
center: new google.maps.LatLng("43.2697,26.9165"),
zoom: 8 };
var map = new google.maps.Map(document.getElementById("map_canvas"),mapOptions);
var marker=new google.maps.LatLng("43.2697,26.9165");
var main=new google.maps.Marker({position:marker});
main.setMap(map);
}
function moveMarker(lat,lng) {
var latlng = new google.maps.LatLng(parseFloat(lat), parseFloat(lng));
//???????
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
Now - in HTML i have a button and two text fields. When button is clicked, it fire moveMarker function and pass new latitude and longitude - entered in fields. The goal is that marker must move to new position, and map must be centered - accordingly. I've tryed a lot of hints, but - cant access marker object(with name Main in my case) in order to move it to new position.
Your marker ("main") is local to your initialize file. To access it from an HTML click event, it needs to be in the global scope.
<script>
var main = null;
function initialize() {
var mapOptions = {
center: new google.maps.LatLng("43.2697,26.9165"),
zoom: 8 };
var map = new google.maps.Map(document.getElementById("map_canvas"),mapOptions);
var marker=new google.maps.LatLng("43.2697,26.9165");
main=new google.maps.Marker({position:marker});
main.setMap(map);
}
function moveMarker(lat,lng) {
var latlng = new google.maps.LatLng(parseFloat(lat), parseFloat(lng));
main.setPosition(latlng);
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>

I'm dynamically loading latitude/longitude variables and passing them to the Google Maps Initialize(); function.
function initialize() {
var lat = $('.map_img', '.inview').attr('data-lat');
var lng = $('.map_img', '.inview').attr('data-lng');
var myLatlng = new google.maps.LatLng(lat, lng);
var mapOptions = {
zoom: 15,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
var marker = new google.maps.Marker({
position: myLatlng,
map: map
});
google.maps.event.trigger(map, 'resize');
}
So I'm pulling these coordinates via the data attribute, which is set via a wordpress widget and giving them to Google Maps.
I want to run the function, getting new coordinates every time the user clicks these left/right buttons.
previous
next
$('.btn-prev').click(function () {
//initialize maps script again
initialize();
});
$('.btn-next').click(function () {
//initialize maps script again
initialize();
});
Then the user clicks on a Map image which opens the large map with the new coordinates.
var mapImg = $('.map_img');
var $overlay = $('.overlay'),
resize = true,
map;
mapImg.click(function () {
$overlay.show();
if (resize) {
initialize();
resize = false;
}
});
The problem I'm having is that after the first click the Map is not centered. I had assumed google.maps.event.trigger(map, 'resize'); would solve this problem.
I'm not sure why this is happening so I've created a fiddle to replicate the issue.
http://jsfiddle.net/SEOplay/3CXSs/13/
Help much appreciated.
Try using:
google.maps.event.addDomListener(window, "click", function () {
var center = map.getCenter();
google.maps.event.trigger(map, "resize");
map.setCenter(center);
});
Not efficient code because I'm not excatly sure how it fits into your code, but it will recenter the map every time someone clicks somewhere. It should give you some idea of the code you need, if you have any trouble let me know.
JSFiddle (you also seem to have a bug where it doesn't change the map on the first next/prev click.
In my App,user can find place Name using click event,after getting place Name,I am showing the place name to user with inputFieldFor this I written the following code.
//helper function
function makingGeocodeRequest(obj,callback){
var geocodeInstance=new google.maps.Geocoder();
geocodeInstance.geocode(obj,callback);
}
google.maps.event.addListener(mapInstane,"click",function(event){
makingGeocodeRequest(_.object(["location"],[event.latLng]),
function(res,status){
document.getElementById("field").value=res[0]["formatted_address"];
}
)
})
Once user click on Save button.I am finding latlng value based on place Name.using the following code
makingGeocodeRequest(
_.object(["address"],[document.getElementById("field").value]),
function(res,status){
if (status===google.maps.GeocoderStatus.OK) {
var latLngObj=res[0]["geometry"]["location"];
console.log(latLngObj;
}
}
)
The problem here,both latlng values are different(click event time latlng value and save button action latlng value).
Actually both are finding from Google,but it's returning different latlng values.
While click event event,I am changing cursor style with this Icon.After click on Save button reverting default cursor.
How can I fix this.Can anyone help me.
Thanks.
To solve your problem you can create and array of points, add marker to this array and render results of the array on the map.
Here is how you can do this :
With Javascript,
<script type="text/javascript">
var map;
var markersList= [];
function initGMap()
{
var latlng = new google.maps.LatLng(39, 20);
var myOptions = {
zoom: 10,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map"), myOptions);
// add a click event handler to the map object and get the lat Lng and then place it on the map
google.maps.event.addListener(map, "click", function(event)
{
// place a marker
placeMarker(event.latLng);
// display the lat/lng in your form's lat/lng fields
document.getElementById("latVal").value = event.latLng.lat();
document.getElementById("lngVal").value = event.latLng.lng();
});
}
// here is the function to place Marker on the map
function placeMarker(location) {
// first remove all markers if there are any
deleteOverlays();
var marker = new google.maps.Marker({
position: location,
map: map
});
// add marker in markers array
markersList.push(marker);
//map.setCenter(location);
}
// Here you can use this function to delete all markers in the array
function deleteOverlays() {
if (markersList) {
for (i in markersList) {
markersList[i].setMap(null);
}
markersList.length = 0;
}
}
</script>
With Html code,
<body onload="initGMap()">
<div id="map"></div>
<input type="text" id="latVal">
<input type="text" id="lngVal">
</body>
Is there a way to hyperlink a custom marker on google maps marker to its coordinates on Google Maps itself? In this case link to LatLng. Also, is there a way to open it in a new tab using target="_blank" or javascript with the same effect?
function initialize() {
var mapOptions = {
zoom: 14,
center: new google.maps.LatLng(-29.528000, 31.194881)
}
var map = new google.maps.Map(document.getElementById('ContactMap'),
mapOptions);
var image = '/Assets/Images/Pages/Marker.png';
var myLatLng = new google.maps.LatLng(-29.528000, 31.194881);
var beachMarker = new google.maps.Marker({
position: myLatLng,
map: map,
icon: image
});
}
google.maps.event.addDomListener(window, 'load', initialize);
A real hyperlink is not possible, but of course you may set up a click-listener to achieve a similar behaviour:
google.maps.event.addListener(beachMarker,'click',function(){
window.open('https://maps.google.com/maps?q=' +
this.getPosition().toUrlValue() +
'&z='+this.getMap().getZoom(),'google');
});
I created a map that focuses on a user's location. The map has a single marker with an info window. When a user clicks on the info window it gives him a hyperlink to an info page (info.html). I want to create an option that will allow the user to go back from the info page to the map, and the map should be focused on the same marker (not on his current location). It's basically going the opposite way. It sounds pretty simple, but I have no idea how to code this.
I guess I can build a different map for every marker, but that seems highly unlikely to be the right solution. Any help would be appreciated.
This is my attempt with the script, (initialize2() doesn't work):
$(document).ready(function() {
getLocation();
});
var map;
var jones = new google.maps.LatLng(40.59622788325198, -73.50334167480469);
function getLocation() {
navigator.geolocation.getCurrentPosition(
function(position) {
var myLatLng = new google.maps.LatLng(position.coords.latitude,position.coords.longitude);
map.setCenter(myLatLng);
},
function() {
alert("Please enable location detection on your device");
}
);
}
function initialize() {
var mapOptions = {
center: map,
zoom: 9,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions);
var infowindow = new google.maps.InfoWindow({
});
var marker1 = new google.maps.Marker({
position: jones,
map: map
});
google.maps.event.addListener(marker1, 'click', function() {
infowindow.setContent('<h4>Jones Beach</h4>See info');
infowindow.open(map,marker1);
});
}
google.maps.event.addDomListener(window, 'load', initialize);
// this is my attempt to focus on the marker
// there will be a button that will evoke this function from info.html
function initialize2() {
var mapOptions2 = {
zoom: 14,
center: new google.maps.LatLng(40.59622788325198, -73.50334167480469),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('map-canvas'),
mapOptions2);
}
google.maps.event.addDomListener(window, 'load', initialize2);
What about using a hash in the url?
Try using "http://students.example.com/test.html#one":
$(function() {
var places = {
one: [40.59622788325198, -73.50334167480469],
two: [50.59622788325198, -71.50334167480469]
};
var div = $('#map-canvas');
var map = new google.maps.Map(div.get(0), {
center: map,
zoom: 9,
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var markers = {};
$.each(places, function(name) {
markers[name] = new google.maps.Marker({
position: new google.maps.LatLng(this[0], this[1]),
map: map
});
});
var place = location.hash.substr(1);
if(place in places) {
map.setCenter(markers[place].getPosition());
}
});
I have a somewhat strange problem. I have two maps on my site, a big one and a small one. I want to use the big one to show a route to a certain address. I'm now trying to implement the two maps but get a weird problem. The small map is working fine, but on the big map only a small area of the div is filled with the map, the rest is empty. (See the image.)
I use the following code to display the two maps:
function initialize() {
var latlng = new google.maps.LatLng(51.92475, 4.38206);
var myOptions = {zoom: 10, center: latlng,mapTypeId: google.maps.MapTypeId.ROADMAP};
var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
var marker = new google.maps.Marker({position: latlng, map:map, title:"Home"});
var image = '/Core/Images/Icons/citysquare.png';
var myLatLng = new google.maps.LatLng(51.92308, 4.47058);
var cityCentre = new google.maps.Marker({position:myLatLng, map:map, icon:image, title:"Centre"});
marker.setMap(map);
var largeLatlng = new google.maps.LatLng(51.92475, 4.38206);
var largeOptions = {zoom: 10, center: largeLatlng,mapTypeId: google.maps.MapTypeId.ROADMAP};
var largeMap = new google.maps.Map(document.getElementById("largeMap"), largeOptions);
var largeMarker = new google.maps.Marker({position: largeLatlng, map:largeMap, title:"Cherrytrees"});
largeMarker.setMap(largeMap);
}
[..]
jQuery(document).ready(function () {
[..]
initialize();
});
What's going wrong here?
EDIT:
Unfortunately the suggestions below doesn't seem to work. The closes i came is to remove the display:none from the elements and set the elements to hide with jquery
[..]
jQuery(document).ready(function () {
[..]
$("#shadow").add($("#shadowContent"),$("#closebar"),$("#content")).hide();
});
With the following result
Yes, #Argiropoulos-Stavros but, Add it as a listener
google.maps.event.addListenerOnce(map, 'idle', function(){
google.maps.event.trigger(map, 'resize');
map.setCenter(location);
});
It will begin re-sizing after, map rendered.
I think you are using v3.
So google.maps.event.trigger(map, "resize");
Also take a look at here
I fixed it!
I made an own function for the largemap and placed it in the callback when the elements are opened
function largeMap(){
var largeLatlng = new google.maps.LatLng(51.92475, 4.38206);
var largeOptions = {zoom: 10, center: largeLatlng,mapTypeId: google.maps.MapTypeId.ROADMAP};
var largeMap = new google.maps.Map(document.getElementById("largeMap"), largeOptions);
var largeMarker = new google.maps.Marker({position: largeLatlng, map:largeMap, title:"Cherrytrees"});
largeMarker.setMap(largeMap);
}
[..]
$("#showRoute").click(function(e){
e.preventDefault();
$("#shadow").add($("#shadowContent"),$("#closebar"),$("#content")).fadeIn(500);
$("#shadowContent").show().css({'width':'750px','top':'25px','left':'50%','margin-left':'-400px'});
$("#closeBarLink").click(function(l){
l.preventDefault();
$("#shadow").add($("#shadowContent"),$("#closebar"),$("#content")).fadeOut(500);
});
largeMap();
});
Thanks anyway!!
call initialize(); function after you box active.
$(document).ready(function () {
$("#shadow").show(function () {
initialize();
})
});
When you're loading in the large map, try adding this at the end of your map code.
map.checkResize();
When Google Maps first renders on your page, it has the dimensions recorded so that it displays the map images in that size. If you're resizing the map dynamically, you need to tell the API to check the new size.
<script type='text/javascript' >
var geocoder, map;
function codeAddress() {
var address= '<?php echo $this->subject()->address; ?>';
geocoder = new google.maps.Geocoder();
geocoder.geocode({
'address': address
}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
var myOptions = {
zoom: 13,
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,
icon:'http://rvillage.com/application/themes/rvillage/images/map-marker.png'
});
var infowindow = new google.maps.InfoWindow({ content: 'coming soon' });
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map, this);
});
}
});
}
jQuery(document).ready(function () {
codeAddress();
});
</script>
You are using pop up window with jQuery, and I guest you call initialize() function when document is ready ( $(document).ready(function() {initialize(); }) ).
Try call initialize() function after pop up windown showed.
