Is it possible to use something similar to maps.controls[google.maps.ControlPosition.TOP_CENTER].push(infoWindow) to have a control window show in the top center of the map?
I have a map with polygons to enable mouseover events. I am trying to also have the infowindow of the polgyon popup in the top-center of the map and disappear on mouseout (I am hoping to avoid using CSS because I would like this to be as pure Google API as possible but I understand that's impossible sometimes).
Polygons are great but the Infowindow keeps displaying at the top left of the screen. Any help would be appreciated! Thank you!
Currently I am getting this error message when I try to mouseover: "Uncaught TypeError: Cannot read property 'zIndex' of undefined"
JS of the part used to create the polygons and add listeners:
function createPolygon(city, url, name){
var infoWindow = new google.maps.InfoWindow();
google.maps.event.addListener(city, 'mouseover', function() {
this.setOptions(
{
fillOpacity: 0.4,
}
);
infoWindow.setContent(name);
console.log(infoWindow);
console.log("City: " + city + " URL: " + url + " Name: " + name);
infoWindow.open(map, this);
map.controls[google.maps.ControlPosition.TOP_CENTER].push(infoWindow);
console.log("awww yis");
});
google.maps.event.addListener(city, 'mouseout', function() {
this.setOptions(
{
fillOpacity: 0.1,
}
);
infoWindow.close();
console.log("awww no");
});
google.maps.event.addListener(city, 'click', function(){
console.log("aaaawww yis");
window.location = url;
});
}
If you want to create a control on the map rather than the infowindow, you can do this (you could also put the content in some other fixed div on your page outside of the map):
function createPolygon(city, url, name) {
var infoWindow = new google.maps.InfoWindow();
var bounds = new google.maps.LatLngBounds();
for (var i = 0; i < city.getPath().getLength(); i++) {
bounds.extend(city.getPath().getAt(i));
}
var center = bounds.getCenter();
google.maps.event.addListener(city, 'mouseover', function() {
this.setOptions({
fillOpacity: 0.4,
});
var textonome = document.createElement('DIV');
textonome.className = "caixabranca";
textonome.innerHTML = "<big><big><b><center>" + name + "</center></big></big></b><br>" + url;
map.controls[google.maps.ControlPosition.TOP_CENTER].push(textonome);
console.log("City: " + city + " URL: " + url + " Name: " + name);
console.log("awww yis");
});
google.maps.event.addListener(city, 'mouseout', function() {
this.setOptions({
fillOpacity: 0.1,
});
map.controls[google.maps.ControlPosition.TOP_CENTER].clear();
console.log("awww no");
});
google.maps.event.addListener(city, 'click', function() {
console.log("aaaawww yis");
window.location = url;
});
}

for (var i = 0; i < subdivision.length; i++) {
arr = [];
var coordinates = xml.documentElement.getElementsByTagName("subdivision")[i].getElementsByTagName("coord");
for (var j = 0; j < coordinates.length; j++) {
arr.push(new google.maps.LatLng(

polygons[polygons.length - 1].setMap(map);
createPolygon(polygons[polygons.length - 1], "", "polygon " + polygons.length);
}
// });
map.fitBounds(bounds);
}
function createPolygon(city, url, name) {
var infoWindow = new google.maps.InfoWindow();
