以下是驗證帳戶代碼的驗證碼,並在特定間隔添加破折號。示例賬戶代碼是140-100-1000-6610-543
。該代碼採用正則表達式:\d{3}-\d{3}-\d{4}-\d{4}-\d{3]
,並允許用戶輸入數字,並在正則表達式中有一個短劃線,它爲用戶放置短劃線。或者說,它應該。在我們的生產服務器上('Qt version:','4.8.1'),('SIP version:','4.13.2'),('PyQt version:','4.9.1')) 。我們的開發服務器升級到('Qt version:','4.8.6'),('SIP version:','4.15.5'),('PyQt version:','4.10.4'),它不會在那裏工作。QValidator修正問題
在每臺服務器上,我輸入140
。在製作(舊版本)上,行編輯值更改爲140-
。在較新的版本開發服務器上,它不添加短劃線。
請讓我知道你是否看到我的問題,並讓我知道這是PyQt問題還是Qt問題。

非常感謝,ekhumoro!你是對的。我們仍然在新服務器上使用2.7,但顯然已經發生了一些變化。再次感謝! – Kerri
