Sorry Mike, I changed my code but it still doesn't work. It did not
raise any error. when I move mouse over the polygon, the alert("Hello
worl") does not work. :(
Herei is my code, please check my error. Really thanks to you so much!
var polys = [];
var labels = [];
var htmls = [];
function CreatePolygon(pts, label, html) {
var poly = new GPolygon(pts,"#000000",0,0,"#0000CC",0,
{clickable:false});
polys.push(poly);
labels.push(label);
htmls.push(html);
GEvent.addListener(poly, "mouseover", function() {
alert("Hello World");
});
return poly;
}
var request = GXmlHttp.create();
request.open("GET", "companies.xml", true);
request.onreadystatechange = function() {
if (request.readyState == 4) {
var xmlDoc = GXml.parse(request.responseText);
// ========= Now process the polylines ===========
var companies =
xmlDoc.documentElement.getElementsByTagName("company");
// read each line
for (var a = 0; a < companies.length; a++) {
// get any state attributes
var label = companies[a].getAttribute("name");
// read each point on that line
var points = companies[a].getElementsByTagName("point");
var pts = [];
for (var i = 0; i < points.length; i++) {
pts[i] = new GLatLng(parseFloat(points[i].getAttribute("lat")),
parseFloat(points[i].getAttribute("lng")));
}
var htmlObject = companies[a].getElementsByTagName("html");
if (htmlObject.length > 0)
var html = htmlObject[0].childNodes[0].nodeValue;
else
var html = "";
// Create Polygon
var myPoly = CreatePolygon(pts, label, html);
map.addOverlay(myPoly);
}
// ================================================
}
}
request.send(null);
