請使用「乾淨」的字@ SO！ – dira 2010-07-14 10:03:44

正確拼寫並停止使用txtspeak，您可能會得到更好的回覆。詛咒社區並不是正確的做法。 – Amy 2010-07-14 10:06:27

我處於危機中，並尋求幫助...只有ppl和gv負面標記去...如果你不能回答，然後去..thats它 – subanki 2010-07-14 10:07:29

是否意味着您要加載的文件名包含在parent.frame_name1.iframe_name1.form_name1.textarea_name1？在這種情況下，您應該動態更改<input type="file"/>的值，這是瀏覽器不支持的（這將是一個安全問題）。
