JWplayer 7 - 添加 active class 到当前播放的视频
JWplayer 7 - Add active class to current playing video
我在我的站点中使用 JWplayer 7（HTML5 渲染模式）。
我创建了一个带有自定义播放列表的播放器，但点击后无法突出显示当前播放的视频。
是否有任何解决方案可以添加自定义 class，例如单击列表项时 .active。
这是我设置 JWplayer 的代码。
var playerInstance = jwplayer("videoCont");
playerInstance.setup({
image: "{PLAYLIST_IMAGE}",
autostart: false,
aspectratio: "16:9",
playlist : "{NV_BASE_SITEURL}{MODULE_NAME}/player/{RAND_SS}{PLAYLIST_ID}-{PLIST_CHECKSS}-{RAND_SS}{FAKE_ID}/",
controls: true,
displaydescription: true,
displaytitle: true,
flashplayer: "{NV_BASE_SITEURL}themes/default/modules/{MODULE_NAME}/jwplayer/jwplayer.flash.swf",
primary: "html5",
repeat: false,
skin: {"name": "stormtrooper"},
stagevideo: false,
stretching: "uniform",
visualplaylist: true,
width: "100%"
});
以及生成自定义播放器的代码
var list = document.getElementById("show-list");
var html = list.innerHTML;
html +="<ul class='list-group'>"
playerInstance.on('ready',function(){
var playlist = playerInstance.getPlaylist();
for (var index=0;index<playlist.length;index++){
var playindex = index +1;
html += "<li class='list-group-item'><span>"+playlist[index].title+"</span><span class='pull-right'><label onclick='javascript:playThis("+index+")' title='Phát "+playlist[index].title+"' class='btn btn-default btn-xs'><i class='fa fa-play'></i></label><label class='btn btn-default btn-xs' href='"+playlist[index].link+"' title='Xem ở cửa sổ mới' target='_blank'><i class='fa fa-external-link-square'></i></label></span></li>"
list.innerHTML = html;
}
html +="</ul>"
});
function playThis(index) {
playerInstance.playlistItem(index);
}
解决方案：基于@zer00ne
的想法
添加以下代码：
playerInstance.on('playlistItem', function() {
var playlist = playerInstance.getPlaylist();
var index = playerInstance.getPlaylistIndex();
var current_li = document.getElementById("play-items-"+index);
for(var i = 0; i < playlist.length; i++) {
$('li[id^=play-items-]').removeClass( "active" )
}
current_li.classList.add('active');
});
之前
function playThis(index) {
playerInstance.playlistItem(index);
}
然后编辑 html 生成如下：
html += "<li id='play-items-"+index+"' class='list-group-item'><span>"+playlist[index].title+"</span><span class='pull-right'><label onclick='javascript:playThis("+index+")' title='"+lang_play+" "+playlist[index].title+"' class='btn btn-primary btn-xs mgr_10'><i class='fa fa-play'></i></label><a href='"+playlist[index].link+"' title='"+lang_new_window+"' target='_blank'><label class='btn btn-default btn-xs'><i class='fa fa-external-link-square'></i></label></a></span></li>"
通过添加 id='play-items-"+index+"' 来识别列表中每个项目的唯一性 class。
更新
Firefox 对 li[i] 有问题，因为它是一个 HTMLCollection (nodeList) 而不是来自 querySelectorAll()。需要添加一个额外的步骤才能将 li[i] 转换为真正的数组。更新涉及一个名为 nodeList2Array(sel).
的函数
更新
我误解了 OP 的要求：
Is there any solution to add a custom class, like .active when click on a item of list.
所以需要的是对生成的自定义播放列表的 <li> 进行操作。
解决方案
在脚本的其余部分之后添加：
jw.on('playlistItem', function() {
var playlist = jw.getPlaylist();
var idx = jw.getPlaylistIndex();
//var li = document.querySelectorAll('.group-list-item');
var li = nodeList2Array('.group-list-item');
for(var i = 0; i < playlist.length; i++) {
if(i === idx) {
li[i].classList.add('active');
}
else {
li[i].classList.remove('active');
}
}
});
function nodeList2Array(sel) {
var li = Array.prototype.slice.call(document.querySelectorAll(sel));
return li;
}

以下演示绝对有效，但您需要输入自己的密钥才能运行。 JW7 没有像 JW6 那样的免费版本。
var jw = jwplayer("media1");
jw.setup({
playlist: "https://content.jwplatform.com/feeds/13ShtP5m.rss",
displaytitle: false,
width: 680,
height: 360
});
var list = document.querySelector(".group-list");
var html = list.innerHTML;
jw.on('ready', function() {
var playlist = jw.getPlaylist();
for (var idx = 0; idx < playlist.length; idx++) {
html += "<li class='group-list-item' title='" + playlist[idx].title + "'><a href='javascript:playThis(" + idx + ");'><img height='75' width='120' src='" + playlist[idx].image + "'><figcaption>" + playlist[idx].title + "</figcaption></a></li>";

您的代码不完全适用于我的网站，但它提供了解决方案。

$('li[id^=play-items-]').removeClass( "active" )
