How can i show multiple locations on google map. I am using this code for google map?
<script type="text/javascript">
$(function() { // when the document is ready to be manipulated.
if (GBrowserIsCompatible()) { // if the browser is patible with Google Map's
var map = document.getElementById("myMap"); // Get div element
var m = new GMap2(map); // new instance of the GMap2 class and pass in our div location.
var longArray= ("<?php echo $long; ?>").split(',');
var latArray= ("<?php echo $lat; ?>").split(',');
for(i=0;i<longArray.length;i++)
{
m.setCenter(new GLatLng(latArray[i], longArray[i]), 13); // pass in latitude, longitude, and zoom level.
m.openInfoWindow(m.getCenter(), document.createTextNode("This is testing")); // displays the text
}
m.setMapType(G_SATELLITE_MAP); // sets the default mode. G_NORMAL_MAP, G_HYBRID_MAP
var c = new GMapTypeControl(); // switch map modes
m.addControl(c);
m.addControl(new GLargeMapControl()); // creates the zoom feature
}
else {
alert("Upgrade your browser, man!");
}
});
</script>

Reset to default 3Refer below code, that worked perfectly fine for me. The code snippet below will give you an error to provide valid API key i.e. "Google Maps JavaScript API error: InvalidKeyMapError", to resolve this the only thing you need is valid API Key provided by google maps.

setCenter is used to zoom and center the map.. if you want to mark multiple locations you need to create a marker and place it on the map inside your loop.. there's a good set of tutorials here:
http://econym.uk/gmap/index.htm
If your question relates to showing multiople disparate locations on a single map then you cant, a map can only be centered on one lat/lng at a time..
Its not entirely clear what you're trying to achieve.
Dunc.
following steps you have to follow. 1. make a list of your addresses in javascript aaray. 2. make a utility function to geocode and then put marker by passing address as arguement. 3. iterate over your addresses array and call your marker utility function.
example: map.jsp :: it tales input json string that is list of addresses and the converts it to javascript array: add the jquery and infobox.js by downloading fron google.
