在Chrome或Firefox上使用范围输入进行清理时,HTML视频比在Safari,Internet Explorer 11或Edge上查看时更加笨拙。
有没有办法帮助Chrome& Firefox和其他浏览器一样流畅吗?

奇怪的是,在发布时运行代码段时看起来比在代码段编辑器本身中显得更顺畅(不幸的是,在我尝试使用它的页面上)。
话虽如此,这里有几个例子,其中不同的浏览器行为更明显:
1)在CodePen中,我从中获取灵感:

2)关于JSFiddle:
https://jsfiddle.net/L9fdyg3j/42/
$(document).ready(function(){
var vid = document.getElementById('vid');
var playbackConst = 500;
var initialized = false;
vid.addEventListener('loadedmetadata', function() {
if (!initialized){
var slider = $('#slide');
// set slider max according to video length
var lastFrame = Math.floor(vid.duration) * playbackConst;
slider.attr('max', lastFrame);
// set slider to middle position
slider.attr('value', lastFrame/2);
// also start video in the middle
vid.currentTime = lastFrame/(2 * playbackConst);
// Pause the video immediately ...
vid.pause();
initialized = true;
}
});
// set video to current position of the slider when slider input is modified
$(document).on('input change', 'input', function() {
vid.currentTime = $(this).val()/playbackConst;
});
});
#slide{
width: 640px;
}
