google maps api v3 - open infowindow from an external click

Question

So i have a V3 map which is initialised like this:

function init() {
        var mapCenter = new google.maps.LatLng(51.5081289,-0.128005);
        var map = new google.maps.Map(document.getElementById('map'), {
          'zoom': 6,
          'center': mapCenter,
          'mapTypeId': google.maps.MapTypeId.ROADMAP, 
          panControl: false,
          mapTypeControl: false,
          zoomControl: true,
          zoomControlOptions: {
                style: google.maps.ZoomControlStyle.SMALL,
                position: google.maps.ControlPosition.LEFT_TOP
            },
        });

and a load of markers that look like this:

var marker25837500 = new google.maps.Marker({
              map: map, 
              pop_title: 'blah blah',                                                                                                 
              pop_wind: 'more blah',
                      zIndex: 999,
              icon: 'images/map_icons/s6.png'
            }); 
            google.maps.event.addListener(marker25837500, 'click', onMarkerClick);

and lastly i have a function to open the infowindow on he click of each maker:

var infoWindow = new google.maps.InfoWindow;

var onMarkerClick = OpenInfoWindow;

function OpenInfoWindow() {
          var marker = this;
          infoWindow.setContent('<h3>' + marker.pop_title + '</h3>' +
                                         marker.pop_body);

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

My question is, what do i need to do to make a particular marker (say marker25837500) show its infowindow when a inside the page is clicked - perhaps something like:

<div id="marker25837500">click to see infoWindow!</div>

I'm sure it's easy but i just can see my way though it!

Thanks

Answer 1

You might use trigger event.

$('#marker25837500').click(function () {
    google.maps.event.trigger(marker25837500, 'click')
})

Check this- https://developers.google.com/maps/documentation/javascript/reference#event

Edit: Also noticed that you are calling onMarkerClick() when marker25837500 is clicked, but you named the other function OpenInfoWindow() so you might need to change that too.

Answer 2

You don't have to do anything unusual or simulate a click on the marker; just make sure the OpenInfoWindow function can be reached:

//This is the simple case:
var myDiv = document.getElementById( "marker25837500" );
google.maps.event.addDomListener( myDiv, "click", OpenInfoWindow );

//Or if you have other things that you want to accomplish when this occurs:
var myDiv = document.getElementById( "marker25837500" );
google.maps.event.addDomListener( myDiv, "click", function() {
    OpenInfoWindow();
    //Do other stuff here
});

As long as the InfoWindow is in scope (can be reached when the OpenInfoWindow function is called), this should work fine.
