http://www.yelp.com/c/denver/health
This sites shows Information window on google map while mouse over on result title
Tried as following,
//<![CDATA[
var map;
var geocoder;
var markerArray = [];
function loadMap(params) {
if (GBrowserIsCompatible()) {
geocoder = new GClientGeocoder();
map = new GMap2(document.getElementById('map'));
map.addControl(new GSmallMapControl());
map.addControl(new GMapTypeControl());
map.setCenter(new GLatLng(40, -100), 4);
map.setZoom(8);
searchLocationsNear(params)
}
}
function searchLocationsNear(params) {
var data = JSON.parse(params);
var lenght = data.length;
var bounds = new GLatLngBounds();
for ( var i = 0; i < lenght; i++) {
// check lat and long available with data
if (data[i].enough_for_map) {
var name = data[i].name;
var address = data[i].address;
if (data[i].description)
var description = data[i].description;
var point = new GLatLng(data[i].latitude, data[i].longitude);
var marker = createMarker(point, name, address, description);
map.addOverlay(marker);
markerArray[i + 1] = marker;
var el_index = $('service_name_' + i);
if (el_index) {
el_index.addEvent('mouseover', marker);
// GEvent.addDomListener(el_index, 'mouseover', function() {
// GEvent.trigger(markerArray[i], 'click');
// });
}
bounds.extend(point);
}
}
map.setCenter(bounds.getCenter(), map.getBoundsZoomLevel(bounds));
}
function createMarker(point, name, address, description) {
var marker = new GMarker(point);
var html = '<b>' + name + '</b> <br/><p>' + description + '</p>' + address;
GEvent.addListener(marker, 'click', function() {
marker.openInfoWindowHtml(html);
});
return marker;
}
above map locations pointed from mysql result set.
<h2>
<a id="service_name_1" href="/example/details/bookkeeper/191">Photographer</a>
</h2>
<h2>
<a id="service_name_2" href="/example/details/bookkeeper/192">Teacher</a>
</h2>
<h2>
<a id="service_name_3" href="/example/details/bookkeeper/193">Accountant</a>
</h2>
Excepted result:
While mouseover on each h2 should show corresponding location info on map.
Any suggestion will greatly appreciated
Thanks

How far have you gotten?
In principle you could,
Put a standard 'click'-event listeners on the markers you've placed on the map which displays the custom infoWindow (a few different approaches/examples here: http://code.google.com/intl/sv-SE/apis/maps/documentation/javascript/demogallery.html).
Have another listener for 'mouseover' on the li elements of the sidebar-list, which in turns triggers the click-event. (Here's how to trigger google map events: http://code.google.com/intl/sv-SE/apis/maps/documentation/javascript/reference.html#event)
