我有一系列视频,当一个结束时,阵列中的下一个应播放 我找到了这个脚本:
function myNewSrc() {
var myVideo = document.getElementsByTagName("video")[0];
myVideo.src =
"http://cheerioscoupons.info/wp-content/uploads/_Cheerios-Coupons-1-300x283.jpg";
myVideo.load();
myVideo.play();
}
function myAddListener(){
var myVideo = document.getElementsByTagName("video")[0];
myVideo.addEventListener('ended',myNewSrc,false);
}
但我在当前脚本中实现它时遇到了麻烦,即
var numb = $(this).index(),
videos = [
"images/talking1.m4v",
"images/talking2.m4v",
"images/talking1.m4v",
"images/talking2.m4v",
"images/talking1.m4v",
"images/talking2.m4v"
],
myVideo = document.getElementById("myVid");
myVideo.src = videos[numb];
myVideo.load();
setTimeout(function(){
myVideo.play();
}, 200);
所以,有两个问题:
答案 0 :(得分:5)
<强> 1 强>
document.getElementsByTagName
将返回一个元素数组,而不是一个元素。所以
var myVideo = document.getElementsByTagName("video");
myVideo.addEventListener('ended',myNewSrc,false); //wrong
var myVideo = document.getElementsByTagName("video");
myVideo.load(); //wrong
myVideo.play(); //wrong
应该是什么:
myVideo[0].load() //if there is only one
for(var i=0;i<myVideo.length;i++){
myVideo[i].load(); //if there is more
}
<强> 2 强>
在ended
之后播放另一个视频,
var videos = [
"images/talking1.m4v",
"images/talking2.m4v",
];
function playArray(index,ele,array,listener){
ele.removeEventListener(listener||0);
ele.src = array[index];
ele.load();
ele.play();
index++;
if(index>=array.length){
index=0;
}
listener = ele.addEventListener('ended',function(){
playArray(index,ele,array,listener);
},false);
}
playArray(0,document.getElementById("myVid"),videos);

答案 1 :(得分:1)
我使用多个文件输入修改了视频输入,以便用户可以选择文件。
https://jsfiddle.net/geqd31pu/
<input id="file" type="file" multiple>
<button onclick="play()">play</button>
<video id="video" src="" autoplay controls></video>
<script>
let index = 0
video = document.getElementsByTagName('video')[0]
play = () => {
const files = document.getElementById('file').files
const file = files[index++ % files.length]
const url = window.URL.createObjectURL(file)
video.src = url
video.load()
}
video.addEventListener('ended', play, false)
</script>
答案 2 :(得分:-1)
播放让索引= 0视频= document.getElementsByTagName('video')[0]播放=()=> {const文件= document.getElementById('file')。files const file = files [index ++%files。长度] const url = window.URL.createObjectURL(file)video.src = url video.load()} video.addEventListener('ended',play,false)
