[英]How to fix “invalid command name” error with Tkinter
解決:正如@furas所說的,我已經在破壞窗口之后嘗試訪問email_text,因此email_text不再存在。
我正在嘗試通過使用tkinter從條目中獲取電子郵件和密碼來自動登錄網站。 該代碼獲取電子郵件和密碼,然后將其輸入站點,然后成功登錄。但是我收到關於email_text.get()行的錯誤。
最初我有一個prepare()和error()函數,因此,如果登錄成功,它將調用error()並提示他們再次登錄。 然后我遇到了同樣的錯誤,想知道這是否是函數中的小部件之間存在一些沖突的問題? 因此,我只是嘗試將其簡化為一個,但是仍然遇到相同的錯誤。 我有3個不同版本的代碼,而且我一直在移動,所以我可能沒有從其他2個版本中移走某些東西,但我無法弄清楚我可能缺少的部分。

如果登錄成功,則該網頁應關閉,但它保持打開狀態,並且出現此錯誤:

@furas是正確的。 您正在嘗試訪問email
條目的內容。 但是在第一次迭代中,關閉窗口后,您嘗試再次訪問它,但是它已經關閉了!
要解決此問題,您可以將my_window.destroy()
從while True
循環移至函數末尾的if語句,因此僅在連接后窗口才會關閉。
