Google Map Infowindow Closure?

as part of my last.fm/google maps event mashup, I have to plot markers dynamically from last.fm API onto the google map. This is all well but when I click the marker, only the last

Solution 1:

An easy way to isolate the scope of your marker variable is to wrap the invocation in an anonymous function:

var map = ...

(function() {
    var image = ...
    var marker = ...
    ...
    google.maps.event.addListener(marker, 'click', function() {
        infowindow.open(map, marker);
    });
})();

As described here, the anonymous function will see anything in scope where it was declared. So inside the function can see map, which was in scope when it was declared. But outside the function, marker is invisible, so repeated clones of the anonymous function won't impact each other.
