This seems to be describing the same code I'm using, but I can't
figure it out. This is what I'm running (apologies I can't show a
page, it's all locked down on company servers...):
function usePointFromPostcode(postcode, callbackFunction, text) {
localSearch.setSearchCompleteCallback(null,
function() {
if (localSearch.results[0])
{
var resultLat = localSearch.results[0].lat;
var resultLng = localSearch.results[0].lng;
var point = new GLatLng(resultLat,resultLng);
callbackFunction(point, text);
}else{
alert("Postcode not found!");
}
});
localSearch.execute(postcode + ", UK");
}
function createMarker(point, text) {
var marker = new GMarker(point, baseIcon);
map.setCenter(point, 12);
map.addOverlay(marker);
GEvent.addListener(marker, "click", function() {
marker.openInfoWindowHtml("<b>" + text + "</b>");
});
return marker;
}
The rest of my script loads the map etc.
On my webpage, I call the function like this:
<script type="text/javascript">
function doStuff()
{
var myPostCode = 'HG1 2RT';
var text = 'Hello';
usePointFromPostcode(myPostCode, createMarker, text);
var myPostCode = 'HG1 4RT';
var text = 'Goodbye';
usePointFromPostcode(myPostCode, createMarker, text);
}
addLoadEvent(doStuff);
</script>
This results in two markers, correctly placed, both with the text
'Goodbye'. How can I fix this?
Thanks
