Hi,
I've successfully set up on my website the example geocoded googlemap with markers from here:
http://code.google.com/support/bin/a...y?answer=65622
I now want to add a search box to geocode a typed in location, and re-center the map on that location. The following code works fine:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<title>Geocoding With a Map</title>
<script src="http://maps.google.co.uk/maps?file=api&v=2&key=ABQIAAAAX4g7w-cn0uZeONcdmA1HYBR30_VdjOSbYvp8XHZAJPWnMA2DJRRNtMqm bzS1zsu9lGThbHrg5l-qTQ" type="text/javascript"></script>
<script type="text/javascript">
var map = null;
var geocoder = null;
function load()
{
if (GBrowserIsCompatible())
{
map = new GMap2(document.getElementById("map"));
map.setCenter(new GLatLng(53.799637, -1.54911), 6);
geocoder = new GClientGeocoder();
}
}
function findAddress(anAddress)
{
if (geocoder)
{
geocoder.getLatLng(anAddress, function(aPoint)
{
if (!aPoint)
{
alert("Sorry, can't locate [" + anAddress + "]");
}
else
{
map.setCenter(aPoint, 13);
var elem = document.getElementById("latLng");
elem.innerHTML = aPoint.lat() + ", " + aPoint.lng();
}
});
}
}
</script>
</head>
<body onload="load()" onunload="GUnload()">
<form action="#" onsubmit="findAddress(this.address1.value); return false">
<p>
<input type="text" size="60" name="address1" value="Type in city/town/village or postcode" />
<input type="submit" value="Go!" />
</p>
<div id="map" style="width: 500px; height: 500px"></div>
<p>Latitude/Logitude: <span id="latLng">51.500789, -0.142264</span></p>
</form>
</body>
</html>
However, when I try to insert this code into the map with markers, it doesn't work. When the location is typed into the search box, the map does not re-center. I've looked at the code until I've gone cross-eyed, and I just cannot figure out why it doesn't work. If anyone can help, I'd be really grateful.
Thanks
Here's the non-working code:
