The original code snipped was:
geocoder.getLatLng(stories[i].city, function plotCity
(latlng) {
I realized it should've been:
geocoder.getLatLng(stories[i].city, function(latlng) {
instead.
If we go by your claim, then stories[i] should be accessible, right ?
But accessible the page still shows "stories[i] is undefined". Where
as
geocoder.getLatLng(stories[i].city, function(latlng, stories[i] { }));
gives error as "missing ) after formal parameters".
How should the parameter be passed in this case ?
If the function is invoked as:
geocoder.getLatLng(stories[i].city, plotCity(latlng, stories[i]));
then the current story object is passed.
