<script type="text/javascript">
var geocoder;
var map;
function initialize() {
geocoder = new google.maps.Geocoder();
var latlng = new google.maps.LatLng(6.5,80.0);
var myOptions = {
zoom: 12,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
}
function codeAddress() {
var address = document.getElementById("address").value;
geocoder.geocode( { 'address': address}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
map.setCenter(results[0].geometry.location);
var marker = new google.maps.Marker({
map: map,
position: results[0].geometry.location
});
} else {
alert("Geocode was not successful for the following reason: " + status);
}
});
}
</script>
<body onload="initialize()">
<div>
<input id="address" type="textbox" value="" />
<input type="button" value="Geocode" onclick="codeAddress()" />
</div>
<div id="map_canvas" style="height:90%">
</div>
</body>
here is the correct answer…
var marker = null;
function codeAddress() {
var address = document.getElementById("address").value;
geocoder.geocode( { 'address': address}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
map.setCenter(results[0].geometry.location);
if(marker == null){
marker = new google.maps.Marker({
map: map,
position: results[0].geometry.location
});
}else
marker.setPosition(results[0].geometry.location);
} else {
alert("Geocode was not successful for the following reason: " + status);
}
});
}
try this
declare marker after map declare
