從數據庫註釋到Ti.map Appcelerator

Question

我想創建一個數組，將本地數據庫中的值推入到Titanium中的註釋中。註釋不響應我的數據庫的值。我想我在某個地方犯了一個學校男孩的錯誤，但我一直在盲目盯着自己。誰能幫我？ 非常感謝！ 乾杯。

功能的LocalDB（）{

var db = Ti.Database.install('/my_db/annotations.sqlite', 'Annos'); 
var row = db.execute('select title, latitude, longitude, type from annotations '); 
places = []; 

while (row.isValidRow()){ 
     var annotation = Titanium.Map.createAnnotation({ 
       latitude:row.fieldByName('latitude'), 
       longitude:row.fieldByName('longitude'), 
       title:row.fieldByName('title'), 
       subtitle:row.fieldByName('type'), 
       animate:true, 
       pincolor: Titanium.Map.ANNOTATION_GREEN 
    }); 

     places.push(annotation); 
     mapview.addAnnotation(annotation); 
     row.next(); 

} 

mapview.annotations = places; 
db.close(); 

}

var mapview = Titanium.Map.createView({ 
    mapType: Titanium.Map.STANDARD_TYPE, 
    height: '100%', 
    animate:true, 
    regionFit:true, 
    userLocation:true, 

}）;

localdb（）;

win.add（mapview）;

你想使用addAnnotations方法通過註釋的陣列創建 http://docs.appcelerator.com/titanium/latest/#!/api/Titanium.Map.View-method-addAnnotations

var places = []; 

while (row.isValidRow()){ 
    var annotation = Titanium.Map.createAnnotation({ 
      latitude:row.fieldByName('latitude'), 
      longitude:row.fieldByName('longitude'), 
      title:row.fieldByName('title'), 
      subtitle:row.fieldByName('type'), 
      animate:true, 
      pincolor: Titanium.Map.ANNOTATION_GREEN 
}); 
    places.push(annotation); 
    row.next(); 
} 
// optional mapview.removeAllAnnotations(); 
mapview.addAnnotations(places);
