google places api/google maps: “listings by…” doesn't get reset-keeps cluttering the map area [closed]

问题

I have a website pune.org that uses places API. As you can see however if I select markers the Listings by lines just keep getting added and eventually make the entire map area useless.

How can I reset the Listings by or ideally to just show Listings by of the marker that is currently selected?

Thanks, Sandeep

You're instantiating the Places Service several times in your code, every time the map pans for example. You need to set a global variable named service at the beginning, then instantiate the Places Service once (*during your map initialization would be appropriate). Then you can simply call the service.search method in your other functions, rather than instantiating the service over and over.

So:

var service;
\\Rest of other global variables
function initializeMap(initialLat, initialLng, detectCurrentLocation, radius,
        zoomLevel, defaultType) {
    initialLocation = new google.maps.LatLng(initialLat, initialLng);
    geocoder = new google.maps.Geocoder();

    var myOptions = {
        zoom : zoomLevel,
        mapTypeId : google.maps.MapTypeId.ROADMAP
    };
    map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
    service = new google.maps.places.PlacesService(map); //Only do this once!
    ...//rest of your code
}

Then remove the other instances of service = new google.maps.places.PlacesService(map); in your code and only call service.search(request, callback);
