hi. I want to add a google map(with street view) in my site. I use this code. when I clicked the point on the map, it can change the street view to this part and show the click point information. But how to add a Red balloons marker in the click point? Then I click in the other point, the first Red balloons marker will move to the new point.( just click for move the marker, not drag the marker). Thanks.

This is the js code I use on one of my sites. I'm sure you can put the right stuff in yours.

var _map;
var _marker;
var _mapObject = document.getElementById("googlemap");
var _customIcon;
var gMarkers = [];

function addItem(pLat, pLong, pTitle) {
    if (_mapObject == null)
        return;

    if (_map == null) {
        _map = new GMap2(_mapObject);
        _map.setCenter(new GLatLng(51.175011,6.020207), 8);
        _map.addControl(new GLargeMapControl());
        _map.addControl(new GMapTypeControl());
        _map.addMapType(G_PHYSICAL_MAP);
        _map.setMapType(G_PHYSICAL_MAP);
        _map.checkResize();
    }
    
    if (_customIcon == null) {
	    _customIcon = new GIcon(G_DEFAULT_ICON);
	    _customIcon.image = "/images/flag_icon.png";
	    _customIcon.iconSize = new GSize(16, 16);
	    _customIcon.iconAnchor = new GPoint(3, 15);
	    _customIcon.shadow = null;
	    _customIcon.shadowSize = null;
    }
    
    point = new GLatLng(pLat, pLong);    
    markerOptions = { icon: _customIcon, title: pTitle };
    _marker = new GMarker(point, markerOptions);
    _map.addOverlay(_marker);
    
    gMarkers.push(_marker);
}
