google map polyline infowindow

问题

As continuation to this question, i trying to add the respective json object name to infowindow content as,

 var infowindow = new google.maps.InfoWindow({
  content:i
  });

Which is given in this fiddle but it displays only the name of last object. I also tried with return function as

google.maps.event.addListener(poly, 'click', (function(event, (poly, i)) {
    return function() {
  infowindow.open(map);
  infowindow.setPosition(event.latLng);
    }
  })(poly, i)); 

but no use (fiddle). How can I achieve it?

回答1:

You said "But all brackets are correctly closed.". This is not correct (you have an extra set of parentheses in the function definition):

google.maps.event.addListener(poly, 'click', (function(event, (poly, i)) {
    return function() {
      infowindow.open(map);
      infowindow.setPosition(event.latLng);
    }
  })(poly, i)); 

The event argument belongs to the returned function, and you only need closure on the polygon (poly) and the loop index (i):

google.maps.event.addListener(poly, 'click', (function (poly, i) {
    return function (event) {
        infowindow.setContent(""+i);
        infowindow.setPosition(event.latLng);
        infowindow.open(map);
    };
})(poly, i));

updated fiddle
