Hello everybody
I have taken more hours to do this
but it is not work, i want to try to get ID from datbase
This is my code

function createMarker(point, index, html)
{
// var letter = String.fromCharCode("A".charCodeAt(0) + index);
var letteredIcon = new GIcon(icon0);
var geticon=new GIcon(baseIcon);
var ID= <%=GetHotelID %>; // get ID from database
ID=parseInt(ID);
var locations = xmlDoc.documentElement.getElementsByTagName("locat ion");
var m;
var hotelids = xmlDoc.getElementsByTagName("hotelid");
var hnames = xmlDoc.getElementsByTagName("hname");
for (m=0;m<locations.length;m=m+1)
{

var hotelid = parseInt(hotelids[m].firstChild.nodeValue);
var hotelname = hnames[m].firstChild.nodeValue;
alert(hotelid +'=' + ID ) ;
if (hotelid=ID) //compare hotelid with ID to appeare
{
var marker = new GMarker(point, letteredIcon);
}
else
{
var marker = new GMarker(point, geticon);
}
}
GEvent.addListener(marker, "mouseover", function()
{ marker.openInfoWindowHtml(html); }
);
markerList[index] = {marker:marker, html:html};
return marker;

}
