如何添加谷歌地圖監聽器點擊數組標記內的InfoWindows？

Question

它告訴我「遺漏的類型錯誤：無法調用未定義的‘開放’」

這是我的代碼

var markers = new Array(); 

      for(var i = 0; i < res.length; i = i + 4){ 
       if(res[i] == "") break; 
       shopLatLng = new google.maps.LatLng(res[i + 2], res[i+3]);     

       markers[i] = new google.maps.Marker({ 
        position: shopLatLng, 
        map: map, 
        title: res[i], 
       }); 

       var infoWindows = new Array(); 
       infoWindows[i] = new google.maps.InfoWindow({ 
        content: res[i + 1] 
       }); 


       google.maps.event.addListener(markers[i], 'click', function(){ 
        infoWindows[i].open(map, markers[i]);      
       }); 



       //console.log("Loja: " + res[i]); 
       //console.log("Categoria: " + res[i + 1]);         
       //console.log("Latitude: " + res[i + 2]); 
       //console.log("Longitude: " + res[i + 3]);    
      } 

var這個「資源」是一個字符串數組...

只是猜測你的變量i沒有得到異步點擊事件的closure'd。

嘗試改變此：

google.maps.event.addListener(markers[i], 'click', function() { 
    infoWindows[i].open(map, markers[i]); 
}); 

這樣：

(function (i) { 
    google.maps.event.addListener(markers[i], 'click', function() { 
     infoWindows[i].open(map, markers[i]); 
    }); 
})(i);
