無法在Adobe AIR中獲取保存的數據ELS

Question

我試圖使用以下代碼保存並從Adobe AIR應用程序獲取數據。但它只是保持警報只有未定義。有人能找到錯誤嗎？

  function saveData(n, v){ 
       var bytes = new air.ByteArray(); 
       bytes.writeUTFBytes(v); 
       return air.EncryptedLocalStore.setItem(n, bytes); 
      } 

      function getData(n){ 
       var storedValue = air.EncryptedLocalStore.getItem(n); 
       return air.trace(storedValue.readUTFBytes(storedValue.length)); 
      } 

      saveData('item1', 'value1'); 
      alert(getData('item1')); 

Answer 1

嘗試刪除air.trace功能

function saveData(n:String, v:String):void 
{ 
    var bytes = new air.ByteArray(); 
    bytes.writeUTFBytes(v); 

    air.EncryptedLocalStore.setItem(n, bytes); 
} 

function getData(n):String 
{ 
    var storedValue = air.EncryptedLocalStore.getItem(n); 

    return storedValue.readUTFBytes(storedValue.length); 
} 

saveData("item1", "value1"); 
alert(getData("item1"));
