刪除存儲在對象中的谷歌地圖標記

我想用存儲在數據庫中的位置的標記填充Google地圖，然後允許用戶通過雙擊要刪除的標記來刪除任何標記。使用下面的代碼填充地圖，但是當雙擊任何標記時，最後一個標記被刪除。刪除存儲在對象中的谷歌地圖標記

我認爲這是因爲雙擊事件監聽器被重新分配到當前標記，但我不知道如何阻止這種情況發生。

我有一個的jsfiddle在這裏設立http://jsfiddle.net/simonbarker/TA4HP/

var markers = {"locations": [{"name" : "UK 1", "date" : "Nov 1", "lat" : 51, "lng" : 0.164}, 
           {"name" : "France 1", "date" : "Nov 2", "lat" : 50, "lng" : 0.164}, 
           {"name" : "France 2", "date" : "Nov 2", "lat" : 49, "lng" : 0.164}] 
       }; 

    var map; 
    var center = new google.maps.LatLng(markers.locations[1].lat,markers.locations[1].lng); 

    var mapOptions = { 
    zoom: 8, 
    center: center, 
    mapTypeId: google.maps.MapTypeId.ROADMAP 
    } 

    map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions); 

    createMarkers(); 


    //create markers by traversing throught the markers object 
    function createMarkers(){ 

    var i = 0; 
    while(markers.locations[i]){ 

     var marker = new google.maps.Marker({ 
      position: new google.maps.LatLng(markers.locations[i].lat, markers.locations[i].lng), 
      animation: google.maps.Animation.DROP, 
      map: map 
     }); 

     //store marker in the locations object 
     markers.locations[i].marker = marker; 

     //add delete handler 
     google.maps.event.addListener(marker, 'dblclick', function(event) { 
     marker.setMap(null); 
     delete markers.locations[i]; 
     }); 

     i++; 

    } 
    }

任何幫助將是巨大的

UPDATE：

我解決了這個改變刪除處理函數

//add delete handler 
      google.maps.event.addListener(marker, 'dblclick', function(event) { 
      this.setMap(null); 
      delete markers.locations[this.id]; 
      });

，創造它時，

var marker = new google.maps.Marker({ 
       id: i, 
       position: new google.maps.LatLng(markers.locations[i].lat, markers.locations[i].lng), 
       animation: google.maps.Animation.DROP, 
       map: map 
      });
