I've been stuck on this for a few days now. I'm having issues adding multiple points to a map using v3 of the Javascript API.



I read this thread and this thread and also this thread on SO and I've caught a few mistakes and made some changes, but I still can't quite get anything to display except for the HTML text in map_canvas.



Any help is much appreciated. Thanks.



Current iteration of code:



<script src=http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js type=text/javascript></script> 
<script src=http://maps.google.com/maps/api/js?sensor=false type=text/javascript></script>
<script type=text/javascript>
$(document).ready(function() { initialize(); });

function initialize() {
var map_options = {
center: new google.maps.LatLng(33.84659,-84.35686),
zoom: 14,
mapTypeId: google.maps.MapTypeId.ROADMAP
};

var google_map = new google.maps.Map(document.getElementById(map_canvas), map_options);

var info_window = new google.maps.InfoWindow({
content: 'loading'
});

var t = [];
var x = [];
var y = [];
var h = [];

t.push('Location Name 1');
x.push(33.84659);
y.push(-84.35686);
h.push('<p><strong>Location Name 1</strong><br/>Address 1</p>');

t.push('Location Name 2');
x.push(33.846253);
y.push(-84.362125);
h.push('<p><strong>Location Name 2</strong><br/>Address 2</p>');

var i = 0;
for ( item in t ) {
var m = new google.maps.Marker({
map: google_map,
animation: google.maps.Animation.DROP,
title: t[i],
position: new google.maps.LatLng(x[i],y[i]),
html: h[i]
});

google.maps.event.addListener(m, 'click', function() {
info_window.setContent(this.html);
info_window.open(map, this);
});
i++;
}
}
</script>
<div id=map_canvas style=width:400px;height:400px;>Google Map</div>

The problem is here:



info_window.open(map, this);


It should be:



info_window.open(google_map, this);


because there's no variable here named map. Working version here: http://jsfiddle.net/nrabinowitz/2DBXY/



If you're not doing so yet, try using a tool like Firebug or the Chrome console - debugging Javascript is almost impossible without one.
