Right not an elegant solution but I still learning about Object
orientated programming language.
What I have done is made each one a new variable and separate
function.
Ie uni checkbox relates to the function uni shops relates to the shops
function
Not very efficient hence why I was looking at different ways.
var check = 0;
var checksh = 0
var checkpu =0;
var map;
var kml_uni = new GGeoXml("http://www.mu130.acres-air.co.uk/Maps/
univeristy.kml");
var kml_pub = new GGeoXml("http://www.mu130.acres-air.co.uk/Maps/
pub.kml");
var kml_shops = new GGeoXml("http://www.mu130.acres-air.co.uk/Maps/
shops.kml");
var kml_church = new GGeoXml("http://www.mu130.acres-air.co.uk/Maps/
church.kml");
var kml_health = new GGeoXml("http://www.mu130.acres-air.co.uk/Maps/
health.kml");
var kml_place = new GGeoXml("http://www.mu130.acres-air.co.uk/Maps/
place.kml");
function initialize() {
map = new GMap2(document.getElementById("map_canvas"));
map.setCenter(new GLatLng(51.8951, -2.0699), 13);
map.addControl(new GLargeMapControl());
map.addControl(new GMapTypeControl());
}
function Univeristy(){
if(check == 1){
map.removeOverlay(kml_uni)
check = 0;
}
else {
map.addOverlay(kml_uni)
check = 1;
}
}
function Shops(){
if(checksh == 1){
map.removeOverlay(kml_shops)
checksh = 0;
}
else {
map.addOverlay(kml_shops)
checksh = 1;
}
}
function Pubs(){
if(checkpu == 1){
map.removeOverlay(kml_pub)
checkpu = 0;
}
else {
map.addOverlay(kml_pub)
checkpu = 1;
}
}
the results will be at this address
