關閉打開的infowindows - 谷歌地圖api

Question

我想，當用戶點擊一個標記，打開並關閉所有以前打開的標記。我試圖用這個代碼沒有運氣，任何想法如何做到這一點？

更新，我使用的是完整的腳本，並基於答案可能的解決方案：

(function($) { 

    /* 
    * new_map 
    * 
    * This function will render a Google Map onto the selected jQuery element 
    * 
    * @type function 
    * @date 8/11/2013 
    * @since 4.3.0 
    * 
    * @param $el (jQuery element) 
    * @return n/a 
    */ 

    function new_map($el) { 

     // var 
     var $markers = $el.find('.marker'); 


     // vars 
     var args = { 
     scrollwheel: false, 
     zoom : 5, 
     center : new google.maps.LatLng(0, 0), 
     mapTypeId : google.maps.MapTypeId.ROADMAP 
     }; 


     // create map   
     var map = new google.maps.Map($el[0], args); 


     // add a markers reference 
     map.markers = []; 


     // add markers 
     $markers.each(function(){ 

      add_marker($(this), map); 

     }); 


     // center map 
     center_map(map); 


     // return 
     return map; 

    }

    function add_marker($marker, map) { 

     // var

     google.maps.event.addListener(marker, 'click', function() {

     bounds.extend(latlng);

     // only 1 marker? 
     if(map.markers.length == 1) 
     { 
     // set center of map 
      map.setCenter(bounds.getCenter()); 
      map.setZoom(16);

     else

我在你的代碼變化不大。

var infoWindows = []; 
if($marker.html()){ 

    // Need to clear up old info windows before adding new ones 
    for (var i = 0; i < infoWindows.length; i++) { 
     infoWindows[i].setMap(null); 
    } 
    // show info window when marker is clicked 
    google.maps.event.addListener(marker, 'click', function() { 

    // create info window 
    var infoWindow = new google.maps.InfoWindow({ 
     content : $marker.html() 
    }); 

    infoWindow.open(map, marker); 
    infoWindows.push(infoWindow); 
    }); 
} 

我希望它能起作用。如果沒有，讓我知道更多關於你的代碼的細節。 謝謝
