I have a working google map via JS with custom styles. I am looking to use this twice on the site, however with a fixed element, the element is set # 0px then transitions to 800px in height. However I need to call the google resize event in order for the map to re-size otherwize it results in a bad UI (clipped map).
Resize Code:
google.maps.event.trigger(map, 'resize');
I have the following code:
function google_map_custom(){
function GoogleMapOptions(){
var markerPosition = new google.maps.LatLng([variable],[variable]),
mapCenter = new google.maps.LatLng([variable],[variable]);
var mapOptions = {
zoom: 15,
scrollwheel: false,
panControl:true,
zoomControl:true,
rotateControl:true,
disableDefaultUI:true,
center: mapCenter,
styles: [
{
"CUSTOM Google JSON": "styles"
},
{}]
};
// ASSOCIATE VARIABLE WITH HTML ID
var mapElement = document.getElementById('google-map');
// Align Settings to DOM Element
var map = new google.maps.Map(mapElement, mapOptions);
// RETINA MARKER (CUSTOM RE-SIZE) - USE VARIABLE BELOW
var image = new google.maps.MarkerImage("[path-to-url]", null, null, null, new google.maps.Size(44,65));
// Tailor Custom Marker (SVG / PNG ACCEPTED) - USE CDN
var marker = new google.maps.Marker({
position: markerPosition,
map: map,
icon:image
});
}
// Trigger map with element id and specific settings above
google.maps.event.addDomListener(window, 'load', GoogleMapOptions);
}
My question is, how do I call the resize event on a click handler? I have this code as an example:
$('[class selector]').click(function(){
$('#google-map.hidden--homepage').toggleClass('[active selector 800px in height]');
// INVOKE FUNCTION
google_map_custom();
});
Just to confirm, transition works, styles work, map loads. I just need to trigger the map when the element is enlarged.
thanks!

I'm working on a javascript Google map where I have marked the location of each of the state capitals with a custom marker and a title of that capital and state. Right now when you view the map you see the whole US with each marker. I want to keep that but add a sidebar where you click the name of a state and the map zooms to the state and capital. I would also like to add a link that zooms out view the full map. Does anyone have a tutorial on how to do this? I found several examples of Google maps with sidebars but none that zooms to a specific location.
Edit:
This is what I am trying to achieve: http://econym.org.uk/gmap/example_map2.htm
Here is the code I am working with:
<script>
function init() {
var myOptions = {
zoom: 4,
center: new google.maps.LatLng(38.781494, -96.064453),
mapTypeId: google.maps.MapTypeId.ROAD
};
var map = new google.maps.Map(document.getElementById("map"), myOptions);
var image = 'Alabama.png';
var myLatLng = new google.maps.LatLng(32.366805, -86.299969);
var AlabamaMarker = new google.maps.Marker({
position: myLatLng,
map: map,
icon: image,
title:"Montgomery, Alabana"
});
}
google.maps.event.addDomListener(window, 'load', init);
</script>
You need to associate listeners (for example, using jquery) with the click event on your state names. Provided they had an id attribute with the USPS code, it would be something like
jQuery(document).on('click','#RESET',function() {
map.setZoom(5);
map.setCenter({lat:41, lng:-89.5});
});
jQuery(document).on('click','#CA',function() {
map.setZoom(7);
map.setCenter({lat:36.4, lng:-120.9});
});
jQuery(document).on('click','#FA',function() {
map.setZoom(7);
map.setCenter({lat:28, lng:-81});
});
You see, I included one link with id RESET that allows me to reset to the initial state.
Here you can see it at work

I am having a hard time trying to add a simple clickable marker to an ArcGIS, map purely using JavaScript. All of the ArcGIS Samples seem to get their marker and related popup information from the server. How can I achieve the same result with ArcGIS as this Google Maps sample code below?
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<div id="map" style="width: 500px; height: 500px;"></div>
<script type="text/javascript">
window.onload = function() {
var myOptions = {
zoom: 2,
center: new google.maps.LatLng(40, -75),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map"), myOptions);
var icon = new google.maps.MarkerImage("http://cinnamonthoughts.org/wp-content/uploads/2010/01/Custom-Marker-Avatar.png");
var markerOptions = {
icon: icon,
map: map,
position: new google.maps.LatLng(37.7699298, -122.4469157),
};
var marker = new google.maps.Marker(markerOptions);
google.maps.event.addListener(marker, 'click', function() {
var infoWindow = new google.maps.InfoWindow();
infoWindow.setContent("hello world");
infoWindow.open(map, marker);
});
};
</script>
Try this:
Create a Point for you longitude and latitude
Convert the point to Web Mercator spatial reference, if it's necessary
Create a PictureMarkerSymbol for you custom picture marker
Create a Graphic using the point and the symbol
Create a GraphicsLayer
Add the graphic to the graphic layer
Add the graphic layer to your map
Add a custom onClick event listener to your layer
Some equivalent code:
var point = new esri.geometry.Point(longitude, latitude);
point = esri.geometry.geographicToWebMercator(point);
var symbol = new esri.symbol.PictureMarkerSymbol("marker.png", 32, 32);
var graphic = new esri.Graphic(point, symbol);
var layer = new esri.layers.GraphicsLayer();
layer.add(graphic);
map.addLayer(layer);
dojo.connect(layer, "onClick", onClick);
On the event listener you can open a custom infoWindow or whatever you like:
function onClick(event) {
map.infoWindow(...)
...
Change "marker.png" and 32x32 to use your custom marker image and dimensions.
Try placing your image icon anywhere on the screen X Y using the CSS positioning then just put your onClick handler inside the actual DIV or IMG tag. Try playing with combination relative vs. absolute to get it just right.
div#header {
position: relative;
}
img#headimg {
position: absolute;
left: whatever you like
top: whatever you like
}
Hi I am showing some markers on my google map and on click of the marker, I am calling the click event and showing some info about that place to the right side(area other than Map and not as an infoWindow). Now this event gets fired on click, and by default when page loads my div remains blank, How can I have the div the basic information being shown up once the map loads up. I need to show the information that corresponds to the marker that is the center point of the map, and later when the users click the marker icons the info should change and correspond to the particular marker being clicked
I have tried something but it doesn't work:
function loadMap() {
var myLatlng = new google.maps.LatLng(40.46998, -3.68705);
var myOptions = {
zoom: 3,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map"), myOptions);
var places = [];
places.push(new google.maps.LatLng(51.43581, -0.51744));
places.push(new google.maps.LatLng(48.87187, 2.31764));
places.push(new google.maps.LatLng(45.45979, 9.19681));
var infowindow;
for(var i = 0; i<places.length; i++) {
var marker= new google.maps.Marker({
position: places[i],
map: map,
title: 'Place' + i
});
(function (i,marker){
google.maps.event.addListener(marker, 'click' , function() {
infowindow.setContent('PLace Number' + i)
infowindow.open(i, marker)
});
});(i, marker);
}
}
$("document").ready(function () {
loadMap();
});
UPDATE EDITED
Basically I need something like Layer KML features
But the info should come on the right hand side by default for the first time. Later on when the marker is clicked, the info should change. I am also not adamant that I need this info in a kml file(xml is fine with me as well). I can just have a marker and info should popup on click and for the first time be default as well depending on the location of the user.
Bottom Line: I need the info to appear on click of a marker and by default when the page loads the info should appear corresponding to the center point of the map. which means users coming from different locations will see different info's corresponding to their location from where they are coming.(I am centering the map based on users location)
You can use the addDomListener event of the google maps api. Something like this:
<script>
function initialize() {
// Map initialization
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
<body>
<div id="map_canvas"></div>
</body>
Although the above code is Maps Javascript API code, the addDomListener() method binds to the window object of the browser and allows the API to communicate with objects outside of the API's normal domain.
further reading
Actually the basic Idea is that you need to read an XMl and parse the data and and show this in a seperate div on right side., This div you can create dynamically when you load the map e-g:
$("#body").append("<div class='newdiv'></div>")
From the google Docs in the section about InfoWindow:
Note that if you call open() without passing a marker, the InfoWindow
will use the position specified upon construction through the
InfoWindow options object.
So in your code, why don't you simply init your infoWindow and call the open() method? I am not particularly familiar with the api, but how about:
var infowindow = new google.maps.InfoWindow({
content: 'your initial text'
});
infowindow.open();
Or if you need the marker for special purposes on the infowindow, init an marker with the center position and use that in the infowindow.open(your_initial_pos) call.
You can use jQuery to .triger() a click event on the first marker on document.ready:
$(marker).trigger('click');
This will run the code you have already written and make it so when the page loads your div will be populated with data from whatever element you trigger the click on.
When you bind to document.ready you don't need encapsulate document in quotes:
$(document).ready(function () {...});
Or you could use the short-hand if you're into that sort of thing:
$(function () {...});
UPDATE
You can place the trigger function call after your for loop where you are setting up the markers:
for(var i = 0; i<places.length; i++) {
var marker= new google.maps.Marker({
position: places[i],
map: map,
title: 'Place' + i
});
(function (i,marker){
google.maps.event.addListener(marker, 'click' , function() {
infowindow.setContent('PLace Number' + i)
infowindow.open(i, marker)
});
});(i, marker);
//only run on the first marker
if (i === 0) {
//trigger a click event to show the first info-window
$(marker).trigger('click');
}
}
You can fire a tilesloaded event on the map object. Check out the Map reference for events
tilesloaded waits until the map tiles are actually loaded before firing. Using your code, you could do something like this:
function loadMap() {
var myLatlng = new google.maps.LatLng(40.46998, -3.68705);
var myOptions = {
zoom: 3,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map"), myOptions);
google.maps.event.addListener(map, 'tilesloaded', function() {
doSomething();
});
I'm having trouble with v3 of the Google Maps API and using the InfoBox plugin specifically with respect to this usability issue use case:
Since my map requires a custom infobox to be opened upon hovering the mouse over each respective marker, when the map has 2 markers on it that are close in proximity, even when/if one of the markers lies behind an infobox that is currently open after hovering the other close-by marker, it is triggered when mousing over it marker (even though it's behind the currently open infobox) and the other infobox obstructs the currently/previously opened infobox
I've followed the question and answer process by another poster here: Google Maps API v3 Event mouseover with InfoBox plugin and have followed the recommended code, but i can't wrap my mind around how to prevent markers that lie BEHIND an open infobox to not be triggered until that infobox is closed.
var gpoints = [];
function initializeMap1() {
var Map1MileLatLang = new google.maps.LatLng(39.285900,-76.570000);
var Map1MileOptions = {
mapTypeControlOptions: {
mapTypeIds: [ 'Styled']
},
mapTypeControl: false,
zoom: 14,
center: Map1MileLatLang,
//mapTypeId: google.maps.MapTypeId.ROADMAP,
mapTypeId: 'Styled'
};
var Map1Mile = new google.maps.Map(document.getElementById("map_canvas"), Map1MileOptions);
var styledMapType = new google.maps.StyledMapType(styles, { name: 'Styled' });//new
Map1Mile.mapTypes.set('Styled', styledMapType);//new
for ( var i=0; i<5; i++ ) {
gpoints.push( new point(Map1Mile) );
gpoints.push( new point2(Map1Mile) );
}
function popup(_point) {
_point.popup = new InfoBox({
content: _point.content,
pane: 'floatPane',
closeBoxURL: '',
alignBottom: 1
});
_point.popup.open(_point.marker.map, _point.marker);
google.maps.event.addListener(_point.popup, 'domready', function() {
//Have to put this within the domready or else it can't find the div element (it's null until the InfoBox is opened)
$(_point.popup.div_).hover(
function() {
//This is called when the mouse enters the element
},
function() {
//This is called when the mouse leaves the element
_point.popup.close();
}
);
});
}
function point(_map) {
this.marker = new google.maps.Marker({
position: new google.maps.LatLng(39.291003,-76.546234),
map: _map
});
this.content = '<div class="map-popup" style="width:100px;"><div class="map-popup-window"><div class="map-popup-content">Just try to click me!<br/>Hovering over this text will result in a <code>mouseout</code> event firing on the <code>map-popup</code> element and this will disappear.</div></div>';
// Scope
var gpoint = this;
// Events
google.maps.event.addListener(gpoint.marker, 'mouseover', function() {
popup(gpoint);
});
}
function point2(_map) {
this.marker = new google.maps.Marker({
position: new google.maps.LatLng(39.295003,-76.545234),
map: _map
});
this.content = '<div class="map-popup" style="width:100px;"><div class="map-popup-window"><div class="map-popup-content">Just try to click me!<br/>Hovering over this text will result in a <code>mouseout</code> event firing on the <code>map-popup</code> element and this will disappear.</div></div>';
// Scope
var gpoint = this;
// Events
google.maps.event.addListener(gpoint.marker, 'mouseover', function() {
popup(gpoint);
});
}
After doing experimenting, i suspect this issue is irrelevant to z-index... am i correct in understanding this needs to be caught in the javascript?
Any help or advice would be greatly appreciated!
Adding optimized: false attribute for your markers should solve the problem.
this.marker = new google.maps.Marker({
position: new google.maps.LatLng(39.295003,-76.545234),
map: _map,
optimized: false
});
I'm playing around with Google maps for the first time, so I looked at a nice tutorial over at CSS Tricks: http://css-tricks.com/google-maps-slider/ I like working with jQuery better than pure JS, and this tutorial makes a nice way to click on a place in a list to display the marker in the map.
I liked it that way, but I need to add infowindows to the marker. Which I did, but when I click on a place on the list and the map pans away, the infowindow stays open! I think it's because I need to attach the infowindow.close() to the event of clicking on a "#locations li".
Here's my code, which runs on document.ready:
$(function() {
var chicago = new google.maps.LatLng(41.924832, -87.697456),
pointToMoveTo,
first = true,
curMarker = new google.maps.Marker({}),
$el;
var myOptions = {
zoom: 10,
center: chicago,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map($("#map_canvas")[0], myOptions);
$("#locations li").click(function() {
$el = $(this);
if (!$el.hasClass("hover")) {
$("#locations li").removeClass("hover");
$el.addClass("hover");
if (!first) {
// Clear current marker
curMarker.setMap();
// Set zoom back to Chicago level
// map.setZoom(10);
}
// Move (pan) map to new location
function move(){
pointToMoveTo = new google.maps.LatLng($el.attr("data-geo-lat"), $el.attr("data-geo-long"));
map.panTo(pointToMoveTo);
}
move();
// Add new marker
curMarker = new google.maps.Marker({
position: pointToMoveTo,
map: map
});
// Infowindow: contenido
var contentString = '<p>'+$el.find("h3").html()+'</p>';
contentString += 'hola' ;
var infowindow = new google.maps.InfoWindow(
{
size: new google.maps.Size(150,50),
content: contentString
});
// On click, zoom map
google.maps.event.addListener(curMarker, 'click', function() {
//map.setZoom(14);
infowindow.open(map,curMarker);
});
It looks like you're creating a new InfoWindow for each marker. Quoting from the Google Maps API Docs:
If you only want one info window to display at a time (as is the behavior on Google Maps), you need only create one info window, which you can reassign to different locations or markers upon map events (such as user clicks).
Therefore, you may simply want to create one InfoWindow object just after you initialize your map, and then handle the click event handler as follows:
google.maps.event.addListener(curMarker, 'click', function() {
infowindow.setContent(contentString);
infowindow.open(map, curMarker);
});
Then the InfoWindow should automatically close when you click on a new marker without having to call the close() method.
