Rather than attempt to modify an existing infowindow, it's much easier
to recreate the whole thing and display a new infowindow with new
contents in the same place.
I tend to use a custom event for this purpose. Let's call it
"buttonclick".
One problem is that the onclick code in your button can only access
global variables and functions, and the reference back to your marker is
normally a local variable held by function closure, which is not
available in global context. The fix for that is to copy the local
reference into a global variable, call it "lastmarker".
var lastmarker; // global variable
GEvent.addListener(marker,"click", function() {
lastmarker = marker; // save a global reference
var html = '... <button
onclick="GEvent.trigger(lastmarker,\"buttonclick\")" ... ';
marker.openInfoWindoTabsHtml(...);
});
[Note: watch out for those nested quotes]
GEvent.addListener(marker,"buttonclick", function() {
// this executes when the user clicks the button
// calculate the URL of the file
GDownloadUrl(url, function(data) {
// use that data to construct GInfoWindowTabs
marker.openInfoWindoTabsHtml(...);
});
});
