使用flash builder將自動保存的內容加載到Flex空間中4.5

Question

我現在已經有了將多個組件文本保存到一個文件的想法。但是現在，當我打開該文件時，文件中的所有文本只進入一個組件的文本。下面是代碼，

     <s:click> 

          var f:File = File.desktopDirectory; 

          f.browseForSave("Save As"); 

          f.addEventListener(Event.SELECT, function (event:Event):void { 

          var stream:FileStream = new FileStream(); 

          stream.open((event.target as File),FileMode.WRITE); 

          stream.writeUTFBytes(rte.htmlText); 

          stream.writeUTFBytes(ta.text); 

          stream.writeUTFBytes(rich.text); 

          stream.close(); 

          }); 

         </s:click> 

        </s:Button> 

     <s:click> 

          var f:File = File.desktopDirectory; 

          f.browseForOpen("Select file to open", []); 

          f.addEventListener(Event.SELECT, function (event:Event):void { 

          var fs:FileStream = new FileStream(); 

          fs.open(event.target as File, FileMode.READ); 

          rte.htmlText = fs.readUTFBytes(fs.bytesAvailable); 

          ta.text = fs.readUTFBytes(fs.bytesAvailable); 

          fs.close(); 

          }); 

         </s:click> 

        </s:Button> 

一些建議嗎？

您已經閱讀了fs中的所有流。一旦你執行一次fs.readUTFBytes（fs.bytesAvailable）;讀取頭文件/指針將指示您的文件結尾，因此在下一行中bytesAvailable將爲零。

我建議你使用下面的代碼：

<s:click> 
    var f:File = File.desktopDirectory; 
    f.browseForOpen("Select file to open", []); 

    f.addEventListener(Event.SELECT, function (event:Event):void { 
     var fs:FileStream = new FileStream(); 
     fs.open(event.target as File, FileMode.READ); 

     var dataStr:String = fs.readUTFBytes(fs.bytesAvailable); 

     rte.htmlText = dataStr; 
     ta.text  = dataStr; 

     // if you want only the non formatted text use: ta.text = rte.text; 
     fs.close(); 
}); 
</s:click>
