问题
I have a simple script that adds a marker on a map when you click a button using jQuery mobile and the Google Maps API v3. I want to add a basic infoWindow to that marker, so that when you click on it, it says "Hello World".
This seems like it should be very easy, but I can't seem to get the syntax correct. I'm adding markers like this
$('#map_canvas').gmap('addMarker', { 'position': chicago } );
and I can't seem to find any good examples where you also setup an infowindow when you also set up the marker.
Here is my code. If you save in the jquery-ui-map-3.0-rc\demos\ directory, then all the paths will be correct. When you click 'Add Some More Markers', a marker in the chicago location is added to the map. I want to be able to click on that marker and have an info window pop up that says "Hello World!".

If I change the code inside $(document).ready(function()){} to the following, the marker doesn't even show up anymore.
$(document).ready(function()
{
initialize();
$('.add-markers').click(function() {
//$('#map_canvas').gmap('addMarker', { 'position': chicago, 'content': "Hello World!"} );
$('#map_canvas').gmap({'callback': function() {
var self = this;
self.addMarker({'position': chicago }).click(function() {
self.openInfoWindow({ 'content': 'Hello World!' }, this);
});
}});
});
});
