Javascript 当视频全屏显示时,增加自定义控件上的z索引
我正在用javascript、CSS和HTML编写一个触摸屏视频亭。由于zer00ne的一篇文章,我有一些代码运行得非常好。我在页面上有4个视频,带有用于播放和全屏的自定义控件。当我全屏显示一个视频时,我仍然可以看到它后面其他视频的自定义控件。我不知道为什么,但我可以看出这些值可能与此有关:Javascript 当视频全屏显示时,增加自定义控件上的z索引,javascript,css,html,video,Javascript,Css,Html,Video,我正在用javascript、CSS和HTML编写一个触摸屏视频亭。由于zer00ne的一篇文章,我有一些代码运行得非常好。我在页面上有4个视频,带有用于播放和全屏的自定义控件。当我全屏显示一个视频时,我仍然可以看到它后面其他视频的自定义控件。我不知道为什么,但我可以看出这些值可能与此有关: video::-webkit-media-controls-enclosure { display:none !important; } .vidBar1 { z-index: 2147483647; }
video::-webkit-media-controls-enclosure { display:none !important; }
.vidBar1 { z-index: 2147483647; }
.vidBar2 { z-index: 2147483647; }
.vidBar3 { z-index: 2147483647; }
.vidBar4 { z-index: 2147483647; }
我无论如何都不是一个程序员,我用很多“借来的”代码奋斗了这么久
我想做的是将上述值设置为2147483646,然后在每个视频的全屏按钮的事件侦听器上,使该视频上自定义控件的z索引在全屏上增加1,在全屏退出时减少1。简而言之,当一个视频是全屏的时候,我不想看到任何东西,除了那个视频和它的自定义控件。
我甚至不知道这是不是应该这样做,但我想让这个项目完成,因为我有一个有限的时间来工作,这是最后一件事是不工作。请在这里查看完整的代码,并提前向您表示感谢:`
