錯誤提示

onIOError（FileReference.onIOError 事件偵聽器）

onIOError

onIOError = function(fileRef:FileReference) {}

這是一個上傳用的flash的變數，很多網友反映G盤出現這個錯誤，多試幾次。

類型

ActionScript 2.0 語言

主要功能

當發生輸入/輸出錯誤時調用。

當上載或下載由於下列任何原因而失敗時調用此偵聽器：

當播放器正在讀取、寫入或傳輸檔案時發生輸入/輸出錯誤。

SWF 檔案嘗試將檔案上載到要求身份驗證（如用戶名和密碼）的伺服器。在上載期間，Flash Player 不提供用戶用於輸入密碼的方法。如果 SWF 檔案嘗試將檔案上載到要求身份驗證的伺服器，則上載會失敗。

SWF 檔案嘗試在獨立或外部播放器中從要求身份驗證的伺服器下載檔案。在下載期間，獨立和外部播放器不提供用戶用於輸入密碼的方法。如果這些播放器中的 SWF 檔案嘗試從要求身份驗證的伺服器下載檔案，則下載會失敗。只有在 ActiveX 控制項和瀏覽器外掛程式播放器中，檔案下載才有可能成功。

傳遞到 upload() 中的 url 參數的值包含無效協定。有效協定包括 HTTP 和 HTTPS。

重要說明：只有在瀏覽器中運行的 Flash 應用程式（也就是說使用瀏覽器外掛程式或 ActiveX 控制項的應用程式）可以提供對話框來提示用戶輸入用戶名和密碼以進行身份驗證，然後只用於下載。對於使用外掛程式或 ActiveX 控制項進行的上載或者使用獨立或外部播放器進行的上載和下載，檔案傳輸會失敗。

可用性

ActionScript 1.0；Flash Player 8

參數

fileRef:flash.net.FileReference - 啟動操作的 FileReference 對象。

示例

下面的示例在觸發 onIOError 事件時跟蹤訊息。為簡單起見，此示例中不包含其它事件偵聽器。

import flash.net.FileReference;

var listener:Object = new Object();

listener.onIOError = function(file:FileReference):Void {

trace("onIOError");

}

var fileRef:FileReference = new FileReference();

fileRef.addListener(listener);

fileRef.download("http://www.macromedia.com/NonExistentFile.pdf", "NonExistentFile.pdf");

英語原文

E文好的可以看看原文

onIOError (FileReference.onIOError event listener)

onIOError = function(fileRef:FileReference) {}

Invoked when an input/output error occurs.

This listener is invoked when the upload or download fails for any of the following reasons:

An input/output error occurs while the player is reading, writing, or transmitting the file.

The SWF file tries to upload a file to a server that requires authentication, such as a user name and password. During upload, Flash Player does not provide a means for users to enter passwords. If a SWF file tries to upload a file to a server that requires authentication, the upload fails.

The SWF file tries to download a file from a server that requires authentication, in the stand-alone or external player. During download, the stand-alone and external players do not provide a means for users to enter passwords. If a SWF file in these players tries to download a file from a server that requires authentication, the download fails. File download can succeed only in the ActiveX control and browser plug-in players.

The value passed to the url parameter in upload() contains an invalid protocol. Valid protocols are HTTP and HTTPS.

Important: Only Flash applications that are running in a browser -- that is, using the browser plug-in or ActiveX control -- can provide a dialog to prompt the user to enter a user name and password for authentication, and then only for downloads. For uploads that use the plug-in or ActiveX control, or that upload and download using either the standalone or external players, the file transfer fails.

Availability: ActionScript 1.0; Flash Player 8

Parameters

fileRef:flash.net.FileReference - The FileReference object that initiated the operation.

Example

The following example traces a message when the onIOError event is triggered. For simplicity, none of the other event listeners are included in this example.
