我想創建一個YouTube視頻播放器,每次訪問網頁時重新排列視頻陣列,然後按照排列順序播放它們。創建一個隨機的YouTube視頻播放器
到目前爲止,我的代碼能夠從陣列中隨機挑選一個視頻播放它,然後隨機挑選另一個視頻並播放它。
問題在於視頻重疊。當它隨機化數組時,我希望它們都按順序播放:如3,2,1或2,1,3或3,1,2。沒有重複。
目前它將播放任何次數的任何視頻。
該功能將在每次訪問頁面時對數組進行洗牌,此部分起作用。
function shuffle(array) {
var currentIndex = array.length, temporaryValue, randomIndex;
// While there remain elements to shuffle...
while (0 !== currentIndex) {
// Pick a remaining element...
randomIndex = Math.floor(Math.random() * currentIndex);
currentIndex -= 1;
// And swap it with the current element.
temporaryValue = array[currentIndex];
array[currentIndex] = array[randomIndex];
array[randomIndex] = temporaryValue;
}
return array;
}
這是改編自https://developers.google.com/youtube/iframe_api_reference
// 1. This code loads the IFrame Player API code asynchronously.
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
// 2. This function creates an <iframe> (and YouTube player)
// after the API code downloads.
var player;
var list = ['rgAYRbeO9GI','6wKxfH9NpVE','OJ9qLosjjH8']
shuffle(list); // shuffles the array
function onYouTubeIframeAPIReady() {
player = new YT.Player('player', {
height: '585',
width: '960',
// videoId: list[Math.floor(Math.random() * list.length)],
videoId: list[0], // accesses the first index of the newly sorted list array, Ideally I want to play the next video
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}
// 3. The API will call this function when the video player is ready.
function onPlayerReady(event) {
event.target.playVideo();
}
// 4. The API calls this function when the player's state changes.
// The function indicates that when playing a video (state=1),
// the player should play for six seconds and then stop.
var done = false;
function onPlayerStateChange(event) {
if (event.data == YT.PlayerState.ENDED && !done) { // once the video is finished the onPlayerReady() function repeats.
onPlayerReady();
done = true;
}
}
代碼,我需要一種方法來移動形成列表[0]索引到下一個,我不知道放在哪裏循環。有任何想法嗎?
