倒數計時器問題

Question

我正在使用倒數計時器，並將其設置爲可以由用戶設置。當計時器到達00:00時它應該說「完成！」。出於某種原因，我得到了「完成！」在我啓動計時器之後。點擊暫停並恢復後，顯示我的櫃檯倒計時，但我不確定客戶會因此而變得很酷。任何人都可以告訴我爲什麼會遇到這個問題？謝謝。

斬去初始化代碼混淆我在那裏，因爲它太一會兒注意到你的括號不均衡......

它看起來像你創建計數器和初始化它既的外onclick功能。在這個階段長度爲零。

當您單擊開始按鈕時，長度被設置爲有效時間，但計時器不會重新初始化，因此它以先前設置的零值開始並立即啓動。

當您按暫停時，計算正確的剩餘時間，然後將其傳遞到您在恢復時創建的新計數器，然後繼續正常倒計時。

將counter = new MyCount(length, 100);直接移動到dialog.show();}之後應該確保在單擊設置的定時器按鈕時計數器被初始化並解決問題。
