如何将值添加到回调函数中的正确对象？

下面的代码每次运行while循环时都会覆盖var存储区。所以当回调运行时，商店值通常是商店数组中的最后一个商品。如何将值添加到回调函数中的正确对象？

var stores = []; 
stores.push({'address': "1 California Ave, San Francisco, CA"}); 
stores.push({'address': "16 California Ave, San Francisco, CA"}); 
stores.push({'address': "20 California Ave, San Francisco, CA"}); 
stores.push({'address': "30 California Ave, San Francisco, CA"}); 

var geocoder = new google.maps.Geocoder(); 

var i = 0; 
while(i < stores.length){ 
    var store = stores[i]; 
    geocoder.geocode({'address':store.fullAddress}, function(data, status){ 
      store.latlng = data[0].geometry.location; 
      } 
     }); 
    i++; 
};

如何将正确的latlng添加到正确的商店？

这不起作用，因为var i也会改变。

var i = 0; 
var storesObject = {} 
while(i < stores.length){ 
    var store = stores[i]; 
    storesObject[i] = stores[i]; 
    geocoder.geocode({'address':store.fullAddress}, function(data, status){ 
      storesObject[i].latlng = data[0].geometry.location; 
      } 
     }); 
    i++; 
};

如果我这样做，我该如何将结果与商店数组相匹配？

var i = 0; 
var results = []; 
while(i < stores.length){ 
    var store = stores[i]; 
    geocoder.geocode({'address':store.fullAddress}, function(data, status){ 
      results.push(data[0].geometry.location); 
      } 
     }); 
    i++; 
};

更新的功能范围将固定我的问题：

var i = 0; 
while(i < stores.length){ 
    (function(){ 
    var store = stores[i]; 
    geocoder.geocode({'address':store.fullAddress}, function(data, status){ 
      store.latlng = data[0].geometry.location; 
      } 
    }); 
    })(); 
    i++; 
};

它最终可能会作为重复被关闭。我会离开它，因为人们仍然能够找到它，并且您的头衔可能会抓住一些搜索。 – Pointy

function geocodeAddress(store) { 
    geocoder.geocode({'address':stores[store].address}, function(data, status){ 
    if (status == google.maps.GeocoderStatus.OK) { 
     stores[store].latlng = data[0].geometry.location; 
    } else { 
     alert("Geocode failed: " + status); 
    }

} 
var stores = []; 
stores.push({'address': "1 California Ave, San Francisco, CA"}); 
stores.push({'address': "16 California Ave, San Francisco, CA"}); 
stores.push({'address': "20 California Ave, San Francisco, CA"}); 
stores.push({'address': "30 California Ave, San Francisco, CA"}); 

var geocoder = new google.maps.Geocoder(); 

var i = 0; 
while(i < stores.length){ 
    geocodeAddress(i); 
    i++; 
};
