未定義のプロパティ1を設定できません - javascript/google maps api

Question

私はGoogleマップにマーカーを追加するために使用できる値の配列を作成しようとしていますが、このエラーは引き続き発生します。以下のコードでは、どこに間違っているかについての提案があります（かなり新しい...）。

おかげ ポール

 var result2 = sforce.connection.queryAll("select Name,Lat__c,Long__c, Status__c from Site__c where Lat__c != null"); 

    var records = result2.getArray('records'); 
    var store_locations = new Array(); 
    var Approved_store_locations = new Array(); 
    var Rejected_store_locations = new Array(); 
    var a=0,b=0,c=0; 

    for (var j=0; j< records.length; j++) 
     { 
     var record = records[j]; 

     if (record.Status__c == "IB Approved") 
     { 

      Approved_store_locations[a][1] = [[new google.maps.LatLng(record.Lat__c, record.Long__c)],[record.Name]]; 
      alert(Approved_store_locations[a][1]); 
      a++ 
     } else if (record.Status__c == "Site Dead") 
     { 

      Rejected_store_locations[b][1] = [[new google.maps.LatLng(record.Lat__c, record.Long__c)],[record.Name]]; 
      b++ 
     } else 
     { 

      store_locations[c][1] = [[new google.maps.LatLng(record.Lat__c, record.Long__c)],[record.Name]]; 
      c++ 
     } 

     } 

    map = new google.maps.Map(document.getElementById("map"), myOptions); 
    for (i=0; i < store_locations.length; i++) 
    { 
    marker2 = new google.maps.Marker(
    { 
     position: store_locations[i][0], 
     title: store_locations[0][i], 
     map: map 
    }); 
    iconfile = 'http://maps.google.com/mapfiles/ms/icons/yellow-dot.png'; 
    marker2.setIcon(iconfile); 
    } 

    for (i=0; i < Approved_store_locations.length; i++) 
    { 
    marker3 = new google.maps.Marker(
    { 
     position: Approved_store_locations[i][0], 
     title: store_locations[0][i], 
     map: map 
    }); 
    iconfile = 'http://maps.google.com/mapfiles/ms/icons/green-dot.png'; 
    marker3.setIcon(iconfile); 
    } 


    for (i=0; i < Rejected_store_locations.length; i++) 
    { 
    marker = new google.maps.Marker(
    { 
     position: Rejected_store_locations[i][0], 
     title: store_locations[0][i], 
     map: map 
    }); 
    iconfile = 'http://maps.google.com/mapfiles/ms/icons/red-dot.png'; 
    marker3.setIcon(iconfile); 
    }

は現在、あなただけstore_locations=Array();、内部なしのアイテムを持っています。

アイテムにアクセスしようとする前に、例えば、それを作成する必要があります。コードにこのエラーが表示されない

var store_locations = [[]]; 
    var Approved_store_locations = [[]]; 
    var Rejected_store_locations = [[]]; 
    var a=0,b=0,c=0; 

    for (var j=0; j< records.length; j++) 
     { 
     var record = records[j]; 

     if (record.Status__c == "IB Approved") 
     { 

      Approved_store_locations[a][1] = [[new google.maps.LatLng(record.Lat__c, record.Long__c)],[record.Name]]; 
      alert(Approved_store_locations[a][1]); 
      a++;Approved_store_locations.push([]); 

     } else if (record.Status__c == "Site Dead") 
     { 

      Rejected_store_locations[b][1] = [[new google.maps.LatLng(record.Lat__c, record.Long__c)],[record.Name]]; 
      b++;Rejected_store_locations.push([]) 
     } else 
     { 

      store_locations[c][1] = [[new google.maps.LatLng(record.Lat__c, record.Long__c)],[record.Name]]; 
      c++;store_locations.push([]); 
     } 

     }
