JWplayer 7-将活动课程添加到当前播放的视频中

Question

我在网站上使用JWplayer 7（HTML5渲染模式）。 我创建了一个具有自定义播放列表的播放器，但单击后无法突出显示当前播放的视频。

是否有任何解决方案来添加自定义类，如单击列表项时的.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%"
  });

并按照以下代码生成自定义播放器

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的思想

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);
}

并编辑html这样生成：

    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+"'为列表的每个项目标识唯一的类。

Answer 1

感谢@ zer00ne的想法！ 您的代码不能与我的网站完全兼容，但是可以提供解决方案。

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');
});

此代码将从每个li元素中删除所有“活动”，并找到当前播放索引正确的ID，然后添加“活动”类。

Answer 2

UPDATE

Firefox的li [i]有问题，因为它是HTMLCollection（nodeList），而不是来自querySelectorAll() 。 为了将li [i]转换为真正的数组，需要添加一个额外的步骤。 更新涉及一个名为nodeList2Array(sel)的函数。

UPDATE

我曲解了OP的要求：

是否有任何解决方案来添加自定义类，如单击列表项时的.active。

因此，需要对自定义播放列表的生成的<li>操作。

解

在脚本的其余部分之后添加此代码：

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;
}

以下演示程序肯定可以正常工作，但您需要输入自己的密钥才能使其正常运行。 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>"; list.innerHTML = html; } }); //SOLUTION~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ jw.on('playlistItem', function() { var playlist = jw.getPlaylist(); var idx = jw.getPlaylistIndex(); var li = document.querySelectorAll('.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 playThis(idx) { jw.playlistItem(idx); }

当然可以添加.active这样的类，然后以这种方式应用样式，但是JW7具有大量的CSS Skin文档。 我使用此处详述的技术为皮肤定型：
