var sw = new google.maps.LatLng(25,-126) ;
var ne = new google.maps.LatLng(50,-66) ;
var bounds = new google.maps.LatLngBounds(sw,ne) ;
overlay = new ProjectedOverlay(map,'http://www.usnaviguide.com/ws-2008-02/images/us_counties_projected.png', bounds, {}) ;
document.getElementById("overlayToggle").innerHTML = '<a href="javascript:overlayRemove()">Remove Overlay</a>' ;
}
// Remove the overlay
function overlayRemove()
{
if ( !overlay )
{
return ;
}
overlay.remove() ;
overlay = null ;
document.getElementById("overlayToggle").innerHTML = '<a href="javascript:overlayAdd()">Add Overlay</a>' ;
}
</script>
</head>
<body style="margin:0px; padding:0px;" onload="initialize()">
<div id="map_canvas" style="width:100%; height:90%"></div>
Opacity:
<a href="javascript:overlay.setOpacity(25)">25%</a>
<a href="javascript:overlay.setOpacity(50)">50%</a>
<a href="javascript:overlay.setOpacity(100)">100%</a>
<span id="overlayToggle"></span>
</body>
</html>
จากโคดข้างบนจะได้ผลลัพธ์ http://www.usnaviguide.com/v3maps/ProjectedOverlayTest.htm
จากนั้นผมต้องการปักหมุดบนแผนที่ ที่ดราฟขึ้นมา เมื่อเอาเมาส์ไปชี้ก็แสดง infowindow เพื่อแสดง detail ครับ
ช่วยแนะนำหน่อยคับ

โคดไฟล์ที่ชื่อ ProjectedOverlay
