Question

I created a google maps (api v3) with the number of markers depending on the search results. When I click a marker, it opens an infowindow. What’s the best way to have that infowindow show information associated to its marker? The information related to all the markers is in a json object I receive from an ajax request.

for (i=0; i < result.point.length; i++) {
                    var latLng = new google.maps.LatLng(result.proint[i].Latitude,result.point[i].Longitude);                                    
                    var marker = new google.maps.Marker({
                        position: latLng,
                        title: i.toString()
                        //map: map
                    });
                    markersArray.push(marker);

                    var infowindow = new google.maps.InfoWindow({
                        content: 'specific information associated to the marker clicked'
                    });

                    google.maps.event.addListener(markersArray[i], 'click', function(event) {
                        infowindow.open(map, this);
                    });

Not entirely sure what it is you are trying to do. Where/ what content are you trying to load?

google.maps.event.addListener(marker, 'click', (function(event, index) {
  return function(){
  infowindow.content = markersArray[index].yourcontent;
  // or
  infowindow.content = yourcontentarray[index];
  infowindow.open(map,this);
  }
})(marker,i));

Make sure you declare your marker and infowindow variables outside of a function.
