我有一个使用javascript作为横幅播放的视频。我需要添加字幕曲目,但仅仅将字幕代码添加到视频部分是行不通的。我尝试在视频代码中添加vtt标题代码,但它不起作用。我在视频标签中添加了(track label=“english”kind=“subtitles”srclang=“en”src=“/media/images/home2018/banner/bannervideo3.vtt”)默认值,但这不起作用。我认为js需要以某种方式更新,以包括字幕跟踪(在曲目代码周围添加括号,因为此处不允许使用括号。)
我的代码如下:
<video id="BannerVideo3" class="Banner" muted playsinline loop oncanplaythrough="playBannerVideo3()" controls autoplay muted playsinline>
</video>
<script>
function playBannerVideo3()
{
var videoElement = document.getElementById('BannerVideo3');
try
{
videoElement.play();
}
catch(err) {}
}
var basePosterURL = '/media/Images/Home2018/Banner/BannerVideo3.jpg';
var baseVideoURL = '/media/Images/Home2018/Banner/BannerVideo3.mp4';
function getNameForCurrentWidth()
{
var bodyWidth = document.body.clientWidth; // $('body').width();
if (bodyWidth <= 767)
return '_Phone';
if (bodyWidth <= 990)
return '_Tablet';
return ''; // Desktop
}
var loadedWidthName;
function loadBannerVideo3(posterOnly)
{
var newWidthName = getNameForCurrentWidth();
if(newWidthName == loadedWidthName)
return;
loadedWidthName = newWidthName;
var videoElement = document.getElementById('BannerVideo3');
if (!videoElement.paused)
videoElement.pause();
videoElement.src = '';
videoElement.poster = addToFilename(basePosterURL, loadedWidthName);
if (posterOnly == true)
return;
setBannerVideoSrc(loadedWidthName);
}
function setBannerVideo3Src(newWidthName)
{
// don't play video if in design or edit modes
if( $('body.DesignMode').length == 1 || $('body.EditMode').length == 1)
return;
var videoElement = document.getElementById('BannerVideo3');
videoElement.src = addToFilename(baseVideoURL, newWidthName);
videoElement.load();
}
// load poster as soon as possible
$(function() // document.ready
{
loadBannerVideo3(true);
});
// load and play video after everything else loads
$(window).on('load',function()
{
setBannerVideo3Src(loadedWidthName);
});
var resizeTimeout;
$(window).resize(function()
{
clearTimeout(resizeTimeout);
resizeTimeout = setTimeout(resizeEnd, 200);
});
function resizeEnd()
{
loadBannerVideo();
}
</script>
