Adding an onclick event to google.map marker

Question

I\'m stuck trying to figure out a little bit of JS :( I have a google map

var myCenter=new google.maps.LatLng(53, -1.33);

function initialize()
{
var mapPro         


        

Answer 1

var myLatlng = new google.maps.LatLng(-25.363882, 131.044922);
var mapOptions = {
    zoom: 4,
    center: myLatlng,
    mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);

var marker = new google.maps.Marker({
    position: myLatlng,
    map: map,
    title: 'Hello World!',
    url: 'http://www.google.com'
});
google.maps.event.addListener(marker, 'click', function () {
    window.location = marker.url;
});

If you go to this page: https://google-developers.appspot.com/maps/documentation/javascript/examples/full/marker-simple

and paste the code above into the console you will see that it works.

I think the problem you have is the following, you need to put this line:

google.maps.event.addListener(marker, 'click', function () {
    window.location = marker.url;
});

inside of your initialize function.

This is what I’d use:

var latLng = new google.maps.LatLng(53, -1.33);

var map = new google.maps.Map(document.getElementById('map_canvas'), {
    center: latLng,
    draggable: false,
    mapTypeId: google.maps.MapTypeId.ROADMAP
    scrollwheel: false,
    zoom: 14
});

var marker = new google.maps.Marker({
    animation: google.maps.Animation.DROP,
    icon: 'images/pin.png',
    map: map,
    position: latLng
});

google.maps.event.addDomListener(marker, 'click', function() {
    window.location.href = 'http://www.google.co.uk/';
});

I’m not sure if you can store a url property with a Marker object.

If you need to display multiple markers (i.e. from an API call) then you can use a for loop like this:

for (var i = 0; i < markers.length; i++) {
    (function(marker) {
        var marker = new google.maps.Marker({
            animation: google.maps.Animation.DROP,
            icon: 'images/pin.png',
            map: map,
            position: market.latLng
        });

        google.maps.event.addDomListener(marker, 'click', function() {
            window.location.href = marker.url;
        });
    })(markers[i]);
}

In my case, I have multiple markers and I wanted to know which marker was clicked. I found following solution on google forum - https://groups.google.com/g/google-maps-js-api-v3/c/cAJrWZWdD-8?pli=1

You can reference the clicked marker with 'this':

google.maps.event.addListener(marker, 'click', markerListener);

function markerListener() { alert(this.getPosition()); // this.setIcon(... }

Answer 4

Not sure where your content is but you would need to do the following...

var yourContent = new google.maps.InfoWindow({
    content: 'blah blah'
});

google.maps.event.addListener(marker, 'click', function() {
  yourContent.open(map,marker);
});

Answer 5

Make sure the marker is defined outside of initialize(). Otherwise, it will be undefined if you attempt to assign the click listener outside of initialize().

Also, you may have SAME-ORIGIN issues if you attempt to load url www.google.com, but it should work fine with a local url.

Updated code

var myCenter=new google.maps.LatLng(53, -1.33);

var marker=new google.maps.Marker({
    position:myCenter,
    url: '/',
    animation:google.maps.Animation.DROP
});

function initialize()
{
var mapProp = {
    center:myCenter,
    zoom: 14,
    draggable: false,
    scrollwheel: false,
    mapTypeId:google.maps.MapTypeId.ROADMAP
};

var map=new google.maps.Map(document.getElementById("map-canvas"),mapProp);

marker.setMap(map);
}

google.maps.event.addDomListener(window, 'load', initialize);
google.maps.event.addListener(marker, 'click', function() {window.location.href = marker.url;});

Here's what I've done in the past. The only difference I see between my code and yours is that I set the marker map in the marker options, and you're setting in with marker.setMap(Map);

var marker = new window.google.maps.Marker({
        position: markerPosition,
        map: map,
        draggable: false,
        zIndex: zIndex,
        icon: getNewIcon(markerType != "archive", isBig)
        , animation: markerAnimation
    });


    window.google.maps.event.addListener(marker, 'click', function () {
        // do stuff
    });
