How do I pass the value (not the reference) of a JS variable to a function? [duplicate]

Answer 1

I think we can define a temporary variable to store the value of i.

for (var i = 0; i < results.length; i++) {
 var marker = results[i];
 var j = i;
 google.maps.event.addListener(marker, 'click', function() { 
   change_selection(j);
 }); 
}

I haven't tested it though.
