我正在使用JavaScript和CSS和HTML編碼的觸摸屏視頻自助服務站。我有一些代碼可以很好地工作，這要歸功於zer00ne的發佈。我有4個視頻與自定義控制播放和全屏。當我全屏播放視頻時，我仍然可以看到其後的每個其他視頻的自定義控件。林不知道爲什麼，但我可以看到，這些值可能有一些用它做：在視頻全屏時增加自定義控件的z-index
video::-webkit-media-controls-enclosure { display:none !important; }
.vidBar1 { z-index: 2147483647; }
.vidBar2 { z-index: 2147483647; }
.vidBar3 { z-index: 2147483647; }
.vidBar4 { z-index: 2147483647; }
我沒有以任何方式是一個程序員，我一直在努力了很多剛拿到這個這麼遠了很多的「借來的」代碼。
我想要做的是將上面的值設置爲2147483646，然後在每個視頻的全屏按鈕的事件偵聽器上，該視頻的自定義控件的z索引在全屏上增加1，然後減小1全屏退出時。簡而言之，當1個視頻是全屏時，我不想看到任何視頻和其自定義控件。 我甚至不知道是否應該這樣做，但我希望完成這個項目，因爲我只剩下有限的時間來處理它，而這是最後一次不工作。請在這裏看到整個代碼，並感謝你這麼多提前：`

你應該真的考慮使用javascript動態生成視頻播放器。你現在的代碼是一個相當複雜的混亂，如果你用javascript生成播放器，它將會非常簡短和乾淨。不是一個真正的答案，但它會讓你的代碼更容易更新:) –
是的我很確定，不幸的是，我不認爲我有時間來做這件事，我不能再繼續這個項目。該代碼不需要更新，它將按照其生命週期運行。我知道它一團糟，而且隨着我繼續學習如何實際編寫代碼，我計劃像你提到的那樣做事情。但正如我所說，我只有有限的時間來解決這個問題。 –
