Google Maps API v3 - Mousemove and Click event Combo - google-maps-api-3

If I've got a click event hooked up to my map, and then I hook up a mousemove event, the click event no longer works. I don't suppose anyone knows anything about this? This is in version 3.4 by the way.
As a simple example:
var map;
function initialize() {
var myLatlng = new google.maps.LatLng(-34.397, 150.644);
var myOptions = {
zoom: 8,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
var secondClick = false;
var firstClick = false;
var firstClickLatLng;
var secondClickLatLng;
var lines = [];
google.maps.event.addListener(map, 'mousemove', function (event) {
redrawLine(event);
});
google.maps.event.addListener(map, 'click', function (event) {
if (!firstClick && !secondClick) {
firstClick = true;
firstClickLatLng = event.latLng;
}
else if (firstClick && !secondClick) {
secondClick = true;
firstClick = false;
// draw the polyline here
secondClickLatLng = event.latLng;
//google.maps.event.removeListener(listener);
}
else if (!firstClick && secondClick) {
secondClick = false;
// clear the polyline here
alert("what");
//google.maps.event.removeListener(listener);
}
});
function redrawLine(event) {
if (firstClickLatLng != null) {
var lineCoords = [
firstClickLatLng,
event.latLng
];
var line = new google.maps.Polyline({
path: lineCoords,
strokeColor: "#FF0000",
strokeOpacity: 1.0,
strokeWeight: 2
});
// You need to clear the previous line, otherwise
// it draws loads and loads of lines. I did this
// in case it doesn't manage to clear the previous
// one for some reason.
for (var i = 0; i < lines.length; i++) {
lines[i].setMap(null);
}
line.setMap(map);
lines.push(line);
}
}
}
So a line is drawn for whenever you move the mouse. The problem is that if I were to click for the second time, the click event will not fire.
Ideas?
EDIT
This issue is related: http://www.mail-archive.com/google-maps-js-api-v3#googlegroups.com/msg15878.html
It doesn't explicitly solve my problem though, but others have tested and experienced this.

Sorted, as that link showed, you need to state clickable: false
http://code.google.com/apis/maps/documentation/javascript/reference.html#PolylineOptions

google.maps.event.addListener(poly,"mousemove",function(e){
var _tooltipPolys = $("#tooltipPolys");
if(_tooltipPolys.length == 0) {
_tooltipPolys = $(' \
<div id="tooltipPolys" class="tooltip top" role="tooltip"> \
<div class="tooltip-arrow"></div> \
<div class="tooltip-inner"></div> \
</div> \
');
$("body").append(_tooltipPolys);
$("div.tooltip-inner", _tooltipPolys).text(this.title);
_tooltipPolys.css({
"opacity": ".9",
"position":"absolute"
});
}
var pageX = event.pageX;
var pageY = event.pageY;
if (pageX === undefined) {
pageX = event.clientX + document.body.scrollLeft + document.documentElement.scrollLeft;
pageY = event.clientY + document.body.scrollTop + document.documentElement.scrollTop;
}

map.setCenter and map.Panto will not shift map

I have tried to change the .onchange function multiple times to change map zoom level and center point. Zoom change takes affect, but the map does not change locations.
Any help would be appreciated. I've removed my api key, but otherwise the map will function on its own.
<script>
function detectBrowser() {
var useragent = navigator.userAgent;
var mapdiv = document.getElementById("map");
if (useragent.indexOf('iPhone') != -1 || useragent.indexOf('Android') != -1 ) {
mapdiv.style.width = '100%';
mapdiv.style.height = '100%';
} else {
mapdiv.style.width = '600px';
mapdiv.style.height = '800px';
}
}
function initMap() {
var central = {lat: 39.8282, lng: -98.5795};
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 5,
center: central
});
var fops = 'http://coleprojects.000webhostapp.com/sqteam.png';
document.getElementById("FieldTeamMember").onchange = function() {
map.setZoom(8);
alert(this.value)
map.setCenter(new google.maps.LatLng(this.value));
};
A clue in the javascript console:
InvalidValueError: in property lat: not a number
You need to pass a google.maps.LatLng (or google.maps.LatLngLiteral) to the map.setCenter method:
document.getElementById("FieldTeamMember").onchange = function() {
map.setZoom(8);
var coords=this.value.split(',');
var latLng = new google.maps.LatLng(parseFloat(coords[0]), parseFloat(coords[1]));
map.setCenter(latLng);
};

Show data when Google Maps marker is clicked in markercluster

I am trying to work out how to show custom data when a Google Maps markerclusterer marker is clicked but can't find this documented anywhere.
My markerclusterer code looks like this but my attempt at capturing the click event on a marker is not working:
var markerClusterer = null;
var map = null;
var imageUrl = 'http://chart.apis.google.com/chart?cht=mm&chs=24x32&' +
'chco=FFFFFF,008CFF,000000&ext=.png';
google.maps.event.addDomListener(window, 'load', initialize);
function refreshMap() {
if (markerClusterer) {
markerClusterer.clearMarkers();
}
var markers = [];
var markerImage = new google.maps.MarkerImage(imageUrl,
new google.maps.Size(24, 32));
/*
for (var i = 0; i < 1000; ++i) {
var latLng = new google.maps.LatLng(data.photos[i].latitude,
data.photos[i].longitude)
var marker = new google.maps.Marker({
position: latLng,
icon: markerImage
});
markers.push(marker);
}
*/
for (var i = 0; i < numItemsToShow; ++i) {
var latLng = new google.maps.LatLng(itemsToShow[i].lat, itemsToShow[i].long);
var marker = new google.maps.Marker({
position: latLng,
icon: markerImage
});
markers.push(marker);
}
var zoom = parseInt(document.getElementById('zoom').value, 10);
var size = parseInt(document.getElementById('size').value, 10);
var style = parseInt(document.getElementById('style').value, 10);
zoom = zoom == -1 ? null : zoom;
size = size == -1 ? null : size;
style = style == -1 ? null: style;
markerClusterer = new MarkerClusterer(map, markers, {
maxZoom: zoom,
gridSize: size,
styles: styles[style]
});
}
function initialize() {
map = new google.maps.Map(document.getElementById('map'), {
zoom: 2,
center: new google.maps.LatLng(39.91, 116.38),
mapTypeId: google.maps.MapTypeId.ROADMAP,

var refresh = document.getElementById('refresh');
google.maps.event.addDomListener(refresh, 'click', refreshMap);
var clear = document.getElementById('clear');
google.maps.event.addDomListener(clear, 'click', clearClusters);
google.maps.event.addListener(markerClusterer, 'click', function () {
// do something with this marker ...
this.setTitle('I am clicked');
});
refreshMap();
}
function clearClusters(e) {
e.preventDefault();
e.stopPropagation();
markerClusterer.clearMarkers();
}
This works for me (it opens an infowindow when you mouseover the cluster icon, if you click on the cluster icon, the default behavior is to zoom to the cluster bounds, which makes it hard to see the change of the tooltip/title on the cluster icon):
var infoWindow = new google.maps.InfoWindow();
google.maps.event.addListener(markerClusterer, 'mouseover', function (cluster) {
// do something with this cluster ...
infoWindow.setContent("Mouseover<br>"+cluster.getCenter().toUrlValue());
infoWindow.setPosition(cluster.getCenter());
infoWindow.open(map);
});

ionic for multi marker google map opens last markup

Issue: On click of any markup on Google map, it always opens the last markup.
Please help.
I had the same problem and spend a lot of time to figure out what's going on so I'd like to add the answer for the future generations,lol.
First of all it's a good idea to refer to official Google maps API docs and take a look at "Events section". I found there one interface of adding event listeners to markers that I never seen before(even after googling this issue for few hours).
marker.addListener('click', function() {});
google.maps.event.addListener(marker, 'click', function () {});
It pointed me out to the idea that when you are trying to do it in the loop using an "old" way, your marker variable is obviously equals to the last element of your markers array. And when event really can be triggered your initialization process is finished what means that your variable has always wrong value in anonymous function at the moment it can be really called. So, again, you didn't passed marker as a parameter to that anonymous event handler.
But you still can do what you want. Just use this.inside your event handler. Bellow is my code sample
marker.addListener('click', function() {
var it = this;
$scope.$apply(function() {
$scope.activeEvent = EventService.getShort($scope.events[it.id]);
});
});
I believe that you can try to use this. in "old-style" interface as well.
I had the same problem and I found the solution here. Apparently, you just have to create a function to create the markers and call that function inside the for loop:
var map = new google.maps.Map(document.getElementById("map"), mapOptions);
$scope.map = map; //Attach the map to the scope before adding the markers
$scope.markers=[];
var infowindow = new google.maps.InfoWindow();
var createMarkers = function (benefit){
//Info window's content
var contentString = "<div><div><img class='shop-icon' src='" + benefit.shopicon + "' alt='" + benefit.shopName + "'/><span class='item-text-wrap'>" + benefit.shopName + "</span></div><div class='shop-offer'>"+benefit.benefits.short_benefitText+"</div><div class='card'><img class='card-art' src='"+benefit.cardart+"' alt='"+benefit.card+"'/></div></div>";
var compiled = $compile(contentString)($scope);
//Get location
var locationLatLng = new google.maps.LatLng(benefit.location.lat, benefit.location.lng);
//Create marker
var marker = new google.maps.Marker({
position: locationLatLng,
map: map,
title: benefit.shopName
});
google.maps.event.addListener(marker, 'click', function () {
infoWindow.setContent(compiled[0]);
infoWindow.open($scope.map, marker);
});
$scope.markers.push(marker);
}
//Loop in each benefits and place on Google map
if (typeof $scope.userBenefits !== "undefined" && $scope.userBenefits.length > 0) {
for (var i = 0; i < $scope.userBenefits.length; i++) {
var benefit = $scope.userBenefits[i];
createMarkers(benefit);
}
}

EDIT:
Everything worked as expected once I included the following script inline on the page prior to calling the maps.js file. Thanks everyone!
<script>
$(document).ready(function(){
var latitude = 39.300299;
var longitude = -97.382812;
view_map('./uploads/your_xml_file.xml', latitude,longitude,4);
//scripts to handle mapping are in js/mylibs/map.js.php
});
</script>
Looking at the html and the code you provided above I constructed a fiddle for you:
http://jsfiddle.net/loanburger/qafsex5x/
I added two markers in an xml string at the top in the fiddle.
I basically parse the xml doing this:
var markers = $(xml).find("marker");
Its then simply the same for loop you had:
for (var i = 0; i < markers.length; i++)
{
...
}
The fiddle will show you the markers.

google map viewport auto adjust

I found something nice animated route created by #Chad Killingsworth in this jsfiddle,i just want to ask if it is possible to adjust automatically the viewport of the map so that we can see route where it is headed.
function initialize() {
var mapOptions = {
zoom: 14,
center: new google.maps.LatLng("54.32216667","10.16530167"),
mapTypeId: google.maps.MapTypeId.TERRAIN
};
var map = new google.maps.Map(document.getElementById('map-canvas'),
mapOptions);
var path_start = new Array();
var path_end = new Array();
path_start.push(new google.maps.LatLng("54.32216667","10.16530167"));
path_end.push(new google.maps.LatLng("54.32216667","10.16530167"));
// lots of other points
path_start.push(new google.maps.LatLng("54.36457667","10.12173333"));
path_end.push(new google.maps.LatLng("54.36457833","10.121745"));
var carPolyline = new google.maps.Polyline({
map: map,
geodesic : true,
strokeColor : '#FF0000',
strokeOpacity : 1.0,
strokeWeight : 2
});
var carPath = new google.maps.MVCArray();
for ( var i = 0; i < path_start.length; i++) {
if(i === 0) {
carPath.push(path_start[i]);
carPolyline.setPath(carPath);
} else {
setTimeout((function(latLng) {
return function() {
carPath.push(latLng);
};
})(path_start[i]), 100 * i);
}
}
Thank you in advance.
Add:
map.setCenter(latLng);
to the code that is drawing the polyline.
var carPath = new google.maps.MVCArray();
for ( var i = 0; i < path_start.length; i++) {
if(i === 0) {
carPath.push(path_start[i]);
carPolyline.setPath(carPath);
} else {
setTimeout((function(latLng) {
return function() {
carPath.push(latLng);
map.setCenter(latLng);
};
})(path_start[i]), 100 * i);
}
}
updated fiddle
