I have the below code, it loads ok, but when i click on the map it
doesn't place a marker.
What should happen is that when you click on the map it should place a
marker and when clicked on the map a second time that it should place
a marker at the new location and remove the previous one so that there
is only ever one marker on the map??
<script type="text/javascript">
//<![CDATA[
function createMarker(point,name) {
var marker = new GMarker(point,{title:name});
return marker;
}
function mapclick(ov,pt) {
if (marker) map.removeOverlay(marker);
if (pt) {
marker = createMarker(pt,pt.toUrlValue());
map.addOverlay(marker);
}
var match11 = /\(([-.\d]*), ([-.\d]*)/.exec(pt);
if (match11) {
var lat = parseFloat( match11[1] );
var lon = parseFloat( match11[2] );
lat = lat.toFixed(6);
lon = lon.toFixed(6);
}
document.getElementById("lat").value = lat;
if(document.getElementById("lat").value == "undefined") {
document.getElementById("lat").value = "";
}
document.getElementById("lon").value = lon;
if(document.getElementById("lon").value == "undefined") {
document.getElementById("lon").value = "";
}
}
function load() {
if (GBrowserIsCompatible()) {
var map = new GMap2(document.getElementById("map"));
map.setCenter(new GLatLng(53.558584,-7.987061), 6);
map.addControl(new GLargeMapControl());
var marker = null;
GEvent.addListener(map,"click",function(overlay,point){mapclick
(overlay,point)});
}
}
//]]>
</script>
