I have overlays that are not added on the page load but added when a
user clicks a link. However this method of hiding the buttons won't
work, do you know why? Here is my code and you can see my page here
http://alpha.clickablecommunity.com/
//this function takes in the lat lon and description.
//it checks an array of coordinates and if the coordinates
//are in the array then it removes the marker.
//if they are not in the array then we add them to
//the array and add the marker. keeping the coordinates
//in an array is how I check to see if the marker exists.
function addUserMarker(lat, lon, desc) {
//a string version of our coordinates
//to check the array of coordinates with
var tempCord = lat.toString() + lon.toString();
//we set this to false if it stays that way
//then the coordinates are not in the array
//meaning it's not on the map so we add it
var inMap = false;
var count = 0;
//create the new marker
var tempMarker = new GMarker(new GLatLng(lat, lon));
while (inMap == false && count < arrOfCord.length) {
//if it is in the array then the coordinate is already
//a marker on the map
if (tempCord == arrOfCord[count]) {
inMap = true;
} //it tempCord
count++;
} //while
//if this stayed false then we add it to the map
if (inMap == false) {
arrOfCord.push(tempCord);
//add the description popup box
GEvent.addListener(tempMarker, "click", function() {
tempMarker.openInfoWindowHtml(desc);
});
map.addOverlay(tempMarker);
map.setCenter(new GLatLng(lat, lon), map.getZoom());
} //if inMap
//we need to remove the marker
else {
//remove the marker from the map
tempMarker.hide();
//remove it from the array
arrOfCord.splice(arrOfCord.indexOf(tempCord), 1);
} //else
} //addUserMarker
Keep in mind I am developing this site so it's not always up.
