I currently have a googlemap canvas with a sidebar with links that when clicked, take the user to the latlong location with a marker and infowindow. When the map is loaded, this is centered but when they click the links the map doesnt pan to the center with the marker in the middle.
I have tried added a map.setCenter within my marker function but this makes the map and markers disappear with no errors in my console. Can anyone guide me to a snippet of code or tutorial which could help? Here is my example code:
<script type="text/javascript">
var side_bar_html = "";
var gmarkers = [];
var map = null;
function initialize() {
var myOptions = {
zoom: 12,
center: new google.maps.LatLng(46.18363372751015,12.4530029296875),
mapTypeControl: true,
mapTypeControlOptions: {style: google.maps.MapTypeControlStyle.DROPDOWN_MENU},
navigationControl: false,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"),myOptions);
google.maps.event.addListener(map, 'click', function() {
infowindow.close();
});
var point = new google.maps.LatLng(46.18363372751015,12.4530029296875);
var marker = createMarker(point,"example 1","location 1 info")
var point = new google.maps.LatLng(39.31517545076218, 35.25238037109375);
var marker = createMarker(point,"example 2","location 2 info")
document.getElementById("marker_list").innerHTML = side_bar_html;
}
var infowindow = new google.maps.InfoWindow({
size: new google.maps.Size(150,50),
});
function myclick(i) {
google.maps.event.trigger(gmarkers[i], "click");
}
function createMarker(latlng, name, html) {
var contentString = html;
var marker = new google.maps.Marker({
position:latlng,
map: map
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.setContent(contentString);
infowindow.open(map,marker);
});
gmarkers.push(marker);
side_bar_html += '<a href="javascript:myclick(' + (gmarkers.length-1) + ')">' + name + '<\/a><br>';
}
</script>
If you want the map to center on the marker when it is clicked, you need to write code to do that. By default it pans so the InfoWindow is visible. Change this:
function myclick(i) {
google.maps.event.trigger(gmarkers[i], "click");
}
To something like:
function myclick(i) {
map.setCenter(gmarkers[i].getPosition());
google.maps.event.trigger(gmarkers[i], "click");
}

I need to in InfoWindow show match.offer.text.
Each marker has a different match.offer.text.
This is my code:
var markerImageURL, lat, lng;
if (myoffer) {
markerImageURL = 'assets/img/markers/marker_my.png';
lat = match.lat;
lng = match.lng;
} else {
markerImageURL = 'assets/img/markers/marker_' + match.strength + '.png';
lat = match.offer.lat;
lng = match.offer.lng;
}
var marker = new google.maps.Marker({
position: new google.maps.LatLng(lat, lng),
map: window.googleMap,
icon: {
size: new google.maps.Size(54,56),
url: markerImageURL
},
draggable: false,
visible: true
});
var infowindow = new google.maps.InfoWindow({
content: match.offer.text,
maxWidth: 300
});
window.googleMapMarkers.push(marker);
if(!myoffer) {
window.MVC.Events.GoogleMap.prototype.showInfoWindow(marker, infowindow, match);
}
Event triggered after clicking on the marker:
marker.addListener('click', function() {
infowindow.open(window.googleMap, marker);
}
Please, help me.
The content is applied to the marker on Open therefore your code will apply the content in last item in your loop to all markers, in your openWindow function add the content to a single infoWindow object i.e.
Also the Maps API has its own event wrapper for the click event
function initMarkers(){
//create markers
var marker = new google.maps.Marker();
google.maps.event.addListener(marker, 'click', openInfoWindow(marker, i));
}
var infowindow = new google.maps.InfoWindow();
function openInfoWindow(marker,index){
return function(e) {
//Close other info window if one is open
if (infowindow) {
infowindow.close();
}
var content = marker.offer.text;
infowindow.setContent(content);
setTimeout(function() {
infowindow.open(map, marker);
}, 200);
}
}
I have a problem with my GeoJson layers which I want to cluster (with MarkerClusterer) and then be able to show and hide them via checkboxes or similar. Therefore I tried something like the code below:
function initialize() {
var mapOptions = {
center: new google.maps.LatLng(52.515696, 13.392624),
zoom: 11,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map"),
mapOptions);
var bounds = new google.maps.LatLngBounds();
var barLayer = new google.maps.Data();
var cafeLayer = new google.maps.Data();
barLayer.loadGeoJson('json/eat_drink/bar.geojson');
cafeLayer.loadGeoJson('json/eat_drink/cafe.geojson');
var markerClusterer = new MarkerClusterer(map);
var infowindow = new google.maps.InfoWindow();
markerClusterer.setMap(map);
function displayMarkers(layer) {
var layer = layer;
google.maps.event.addListener(layer, 'addfeature', function (e) {
if (e.feature.getGeometry().getType() === 'Point') {
var marker = new google.maps.Marker({
position: e.feature.getGeometry().get(),
title: e.feature.getProperty('name'),
map: map
});
// open the infoWindow when the marker is clicked
google.maps.event.addListener(marker, 'click', function (marker, e) {
return function () {
var myHTML = e.feature.getProperty('name');
infowindow.setContent("<div style='width:150px; text-align: center;'>"+myHTML+"</div>");
infowindow.setPosition(e.feature.getGeometry().get());
infowindow.setOptions({pixelOffset: new google.maps.Size(0,-30)});
infowindow.open(map, marker);
};
}(marker, e));
markerClusterer.addMarker(marker);
bounds.extend(e.feature.getGeometry().get());
map.fitBounds(bounds);
map.setCenter(e.feature.getGeometry().get());
}
});
layer.setMap(null);
google.maps.event.addListener(map, "click", function () {
infowindow.close();
});
};
document.getElementById('bar').onclick = function(){ // enable and disable markers
if(document.getElementById('bar').checked == true){
displayMarkers(barLayer);
}else{
return null;
}
};
}
Unfortunatley this doesn't work and I don't no exactly why.
If I remove the displayMarkers() function around the code and replace "layer" with the desired GeoJson layer, e.g. "barLayer", it works just fine.
Since I will end up with tons of GeoJason layers I would prefer a "compact" solution like this insted of copying the code multiple times. Have you guys any ideas how to do that properly?
I'm afraid I haven't done much more than refactor your code. Could you give this a try, and if it doesn't work specify exactly what doesn't work?
function displayMarkers(layer, map, markerClusterer) {
google.maps.event.addListener(layer, 'addfeature', function(e) {
if (e.feature.getGeometry().getType() === 'Point') {
var marker = new google.maps.Marker({
position: e.feature.getGeometry().get(),
title: e.feature.getProperty('name'),
map: map
});
// open the infoBox when the marker is clicked
google.maps.event.addListener(marker, 'click', function(e) {
var myHTML = e.feature.getProperty('name');
var infowindow = new google.maps.InfoWindow();
infowindow.setContent("<div style='width:150px; text-align: center;'>" + myHTML + "</div>");
infowindow.setPosition(e.feature.getGeometry().get());
infowindow.setOptions({
pixelOffset: new google.maps.Size(0, -30)
});
infowindow.open(map, marker);
google.maps.event.addListener(map, "click", function() {
infowindow.close();
});
});
markerClusterer.addMarker(marker);
var bounds = new google.maps.LatLngBounds();
bounds.extend(e.feature.getGeometry().get());
map.fitBounds(bounds);
map.setCenter(e.feature.getGeometry().get());
}
});
layer.setMap(null);
}
function initialize() {
var mapOptions = {
center: new google.maps.LatLng(52.515696, 13.392624),
zoom: 11,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map"), mapOptions);
var barLayer = new google.maps.Data();
var cafeLayer = new google.maps.Data();
barLayer.loadGeoJson('json/eat_drink/bar.geojson');
cafeLayer.loadGeoJson('json/eat_drink/cafe.geojson');
var markerClusterer = new MarkerClusterer(map);
markerClusterer.setMap(map);
document.getElementById('bar').onclick = function() { // enable and disable streetViewControl
if (document.getElementById('bar').checked == true) {
displayMarkers(barlayer, map, markerClusterer);
} else {
return null;
}
};

I trying to add gmap to my app.I have on the page table and div with map, and I want to make sure that the user when add marker on the map - in table add one row.
there is my script (default script from google example)
window.onload = function() {
var mapOptions = {
center: new google.maps.LatLng(21.0000, 78.0000),
zoom: 5,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map"), mapOptions);
google.maps.event.addListener(map, 'click', function(e) {
var location = e.latLng;
var marker = new google.maps.Marker({
position: location,
map: map
});
google.maps.event.addListener(marker, "click", function(e) {
var infoWindow = new google.maps.InfoWindow({
content: 'Latitude: ' + location.lat() + '<br />Longitude: ' + location.lng()
});
infoWindow.open(map, marker);
});
});
};
sorry for my bad English
In the Google example you provided, you would do it after the line
google.maps.event.addListener(map, 'click', function(e) {
You could insert something like
$('myTable').append('<tr><td>THIS IS MY NEW ROW</td></tr>');
depending on what your "row" should hold.
I have the following code for placing several markers on a google map.
What I now want to do is when the user clicks on a marker it zooms in and then centers the map to the marker position (this is the bit that's not working - towards the end of the code in the setMarkers function).
Any ideas?
var infowindow = null;
var sites = [];
var partsOfStr = [];
var partsOfStr2 = [];
var bounds;
$(document).ready(function () {
$("select[id*='coordList']").find("option").each(function () {
partsOfStr = $(this).val().split(',');
partsOfStr2 = $(this).text().split('^');
sites.push([partsOfStr2[0], parseFloat(partsOfStr[0]), parseFloat(partsOfStr[1]), partsOfStr[2], partsOfStr2[1], partsOfStr2[2], partsOfStr2[3], partsOfStr[3], partsOfStr[4], partsOfStr[5]]);
});
initialize();
});
function initialize() {
bounds = new google.maps.LatLngBounds();
var mapOptions = {
zoom: 6,
center: new google.maps.LatLng(54.57951, -4.41387),
scrollwheel: false,
mapTypeId: google.maps.MapTypeId.HYBRID
}
var map = new google.maps.Map(document.getElementById('map'), mapOptions);
setMarkers(map, sites);
infowindow = new google.maps.InfoWindow({
content: "loading..."
});
google.maps.event.addListener(infowindow,'closeclick',function(){
map.setCenter(new google.maps.LatLng(54.57951, -4.41387));
map.setZoom(6);
});
}
function setMarkers(map, markers) {
for (var i = 0; i < markers.length; i++) {
var sites = markers[i];
var siteLatLng = new google.maps.LatLng(sites[1], sites[2]);
var marker = new google.maps.Marker({
position: siteLatLng,
map: map,
title: sites[0],
html: "<div class='mapDesc'>content here...</div>"
});
google.maps.event.addListener(marker, "click", function () {
infowindow.setContent(this.html);
infowindow.open(map, this);
map.setCenter(marker.getPosition()); // NOT WORKING!!!!!!!
map.setZoom(10);
});
bounds.extend(new google.maps.LatLng(sites[1], sites[2]));
map.fitBounds(bounds);
}
}
marker is left pointing to the last marker added. Either use function closure or "this" like you did for the infowindow:
google.maps.event.addListener(marker, "click", function () {
infowindow.setContent(this.html);
infowindow.open(map, this);
map.setCenter(this.getPosition());
map.setZoom(10);
});
google.maps.event.addListener(marker, "click", function (evt) {
infowindow.setContent(this.html);
infowindow.open(map, this);
map.setCenter(evt.latLng);
map.setZoom(10);
});
that will working in my own app
We using multiple marker with infowindow. Everything is working fine.
The issue is when we click marker, the infowindow opens but it doesn't close when click other markers. it stay opened. so can give solutions for this issue.
The code is in http://goo.gl/s0WZx
var berlin = new google.maps.LatLng(52.520816, 13.410186);
var neighborhoods = [
new google.maps.LatLng(52.511467, 13.447179),
new google.maps.LatLng(52.549061, 13.422975),
new google.maps.LatLng(52.497622, 13.396110),
new google.maps.LatLng(52.517683, 13.394393)
];
var markers = [];
var iterator = 0;
var map;
function initialize() {
var mapOptions = {
zoom: 12,
mapTypeId: google.maps.MapTypeId.ROADMAP,
center: berlin
};
map = new google.maps.Map(document.getElementById("map_canvas"),
mapOptions);
}
function drop() {
for (var i = 0; i < neighborhoods.length; i++) {
setTimeout(function() {
addMarker();
}, i * 200);
}
}
function addMarker() {
var marker = new google.maps.Marker({
position: neighborhoods[iterator],
map: map,
draggable: false
});
markers.push(marker);
var contentString = $("#pop"+iterator).html();
var infowindow = new google.maps.InfoWindow({
content: contentString,
maxWidth: 300,
maxHeight: 500
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map,marker);
});
iterator++;
}
You are creating as much infowindows, as there are markers. In your case,I think one infowindow is enough. So for working with only one infowindow, you could implement this on global scope:
//Using lazy initialization.
//InfoWindow will be created only after the first call
var getInfoWindow = (function(){
var _instance = null;
return function(){
if(_instance == null){
_instance = new google.maps.InfoWindow({
maxWidth: 300,
maxHeight: 500
});
}
return _instance;
};
})();
Also you need to store the contentString for every marker which must be shown on click event. So the final modification of addMarker method will be something like this:
function addMarker() {
var marker = new google.maps.Marker({
position: neighborhoods[iterator],
map: map,
draggable: false
});
markers.push(marker);
//Storing content html
marker.contentString = $("#pop"+iterator).html();
google.maps.event.addListener(marker, 'click', function() {
//Setting content of InfoWindow
getInfoWindow().setContent( marker.contentString );
//Opening
getInfoWindow().open(map,marker);
});
iterator++;
}
Put the var infowindow outside of the addMarker function. Like this:
var infowindow = new google.maps.InfoWindow();
Then inside your addMarker function use
infowindow.setContent(contentString);
This way the infowindow is only created once. Clicking on the different markers just moves the window and sets the content.
