我有一個非常有趣的困境,那就是讓我頭痛的颶風。我在這裏看到過類似的問題,但用戶沒有發佈代碼,所以沒有解決。這是一個asp.net,sql服務器和c#應用程序。如何防止我的文本框在回發中清除文本。
在我的應用程序,我使用JavaScript來顯示在TextBox
虛擬數據,而一個長期的過程運行到娛樂用戶。 (請注意,這是一個項目,而不是一個專業的應用程序)。
的問題是,一旦應用程序執行完畢,應用程序(我相信)刷新頁面並清除TextBox
。我想防止這種情況發生,並在程序完成後繼續顯示文本。
我的問題是,在下面的代碼是刷新頁面?我如何重新編碼它以防止文本被清除?
我知道JavaScript或.aspx頁面沒有問題。我沒有設置或編制任何財產來清除文本。如果有人能夠解決這個問題,我將不勝感激。如果你需要更多的代碼,請告訴我。我將在此頁面上非常活躍,直到解決問題。再次感謝!

javascript/html在哪裏? – Nate
我使用了後面的代碼。但是,所有的JavaScript都會在文本框中插入文本,就是這樣。你想讓我發佈這些代碼嗎? – javasocute
是否在此代碼中引用了問題中的文本框?你在使用UpdatePanel嗎? – patmortech
