Here is a link to a page containing a Google Map http://www.soundsairpark.com/sandpit/mapTest.html

As it stands I have a zoom event occurring when the marker is clicked. I would like to change this so the zoom event only occurs only when the "zoom" link within the info window is clicked.
Assistance appreciated.
Regards,
N

It's because you have:

function createMarker(point,html) {
        var marker = new GMarker(point);
        GEvent.addListener(marker, "click", function() {
          marker.openInfoWindowHtml(html);
             
             map.setZoom(15);
        });

Do you see the issue? You call "map.setZoom(15)" when the marker is clicked. Change it to:

function createMarker(point,html) {
        var marker = new GMarker(point);
        GEvent.addListener(marker, "click", function() {
          marker.openInfoWindowHtml(html);
        });

Removing the Zoom from the marker click is straight forward I know and yes your answer would do this. However my question relates to how to add an event listener to the word "zoom" inside the info window so that when it is clicked the zoom occurs.

When you create the link, add a javascript onclick event that will call "map.setZoom(15)"

That is the crux of my question and what I having difficulty achieving. The attached code is the info window set up or the full script can be found via the link.

// Set up marker with info windows 
    
      var point = new GLatLng(-41.34204, 173.957801);
      var marker = createMarker(point,'<div style="width:240px; font-family:Arial; font-size:14px"><img src="http://www.soundsairpark.com/sandpit/images/structure/logo-icon.png" width="66" height="48"  style="float:left; margin-right:10px">Marlborough Sounds <br>Air Park<br>SH1, Picton. NZ<br> <a id=zoom" href="#">Zoom<\/a><\/div>')
      map.addOverlay(marker);

Open in new window

Ok, it looks like I have it! Many thanks for pointing me in the right direction. If you are interested I am about to post a related question asking how to create a toggle effect on my button.
Cheers

My solution:<input type="button" id="zoom" value="Zoom" onclick="map.setZoom(15)"/>
