香草js在这里。
var videos = document.querySelectorAll('video'); for(var i=0; i<videos.length; i++) videos[i].addEventListener('play', function(){pauseAll(this)}, true); function pauseAll(elem){ for(var i=0; i<videos.length; i++){ //Is this the one we want to play? if(videos[i] == elem) continue; //Have we already played it && is it already paused? if(videos[i].played.length > 0 && !videos[i].paused){ // Then pause it now videos[i].pause(); } } }
<video height="169" width="300" preload="none" controls="controls"> <source type="video/webm" src="http://video.webmfiles.org/big-buck-bunny_trailer.webm"></source> <source type="video/mp4" src="http://video.webmfiles.org/big-buck-bunny_trailer.mp4"></source> </video> <video height="169" width="300" preload="none" controls="controls"> <source type="video/webm" src="http://video.webmfiles.org/elephants-dream.webm"></source> <source type="video/mp4" src="https://archive.org/download/ElephantsDream/ed_hd.mp4"></source> </video>
Vanilla js here.
var videos = document.querySelectorAll('video'); for(var i=0; i<videos.length; i++) videos[i].addEventListener('play', function(){pauseAll(this)}, true); function pauseAll(elem){ for(var i=0; i<videos.length; i++){ //Is this the one we want to play? if(videos[i] == elem) continue; //Have we already played it && is it already paused? if(videos[i].played.length > 0 && !videos[i].paused){ // Then pause it now videos[i].pause(); } } }
<video height="169" width="300" preload="none" controls="controls"> <source type="video/webm" src="http://video.webmfiles.org/big-buck-bunny_trailer.webm"></source> <source type="video/mp4" src="http://video.webmfiles.org/big-buck-bunny_trailer.mp4"></source> </video> <video height="169" width="300" preload="none" controls="controls"> <source type="video/webm" src="http://video.webmfiles.org/elephants-dream.webm"></source> <source type="video/mp4" src="https://archive.org/download/ElephantsDream/ed_hd.mp4"></source> </video>

香草js在这里。 var videos = document.querySelectorAll('video'); for(var i=0; i这应该可以解决问题,只需确保将“视频”和“图像”指向各自的URL即可。
