JWplayer 7-将活动课程添加到当前播放的视频中

Question

I am using JWplayer 7 (HTML5 render mode) in my site. I created a player with custom playlist, but cannot highlight current playing video when it has been clicked.

Is there any solution to add a custom class, like .active when click on a item of list.

This is my code to setup JWplayer.

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%"
  });

And following code to generate custom player

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);
    }

---

SOLUTION : Based on an idea of @zer00ne

Add following code :

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');
});

before

function playThis(index) {
    playerInstance.playlistItem(index);
}

And edit html generate like this :

    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>"

With adding id='play-items-"+index+"' to identify unique class for each item of list.

Answer 1

Thanks for idea of @zer00ne ! Your code not total works with my site but it give a solution.

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');
});

This code will remove all "active" from each li element and find the ID is correct with current playing Index, then add "active" class.

UPDATE

Firefox has a problem with li[i], since it's a HTMLCollection (nodeList) and not live coming from querySelectorAll() . One extra step needs to be added in order to convert li[i] to a true Array. The update involves a function called nodeList2Array(sel) .

UPDATE

I misinterpreted the OP's request:

Is there any solution to add a custom class, like .active when click on a item of list.

So what is needed is manipulation of the generated <li> s of the custom playlist.

SOLUTION

Add this after the the rest of the script:

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;
}

!!!IMPORTANT PLEASE READ THIS!!!

The following demo DEFINITELY WORKS, but you need to enter your own key in order for it to function. JW7 does not have a free version like JW6 does.

 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); }

Sure it's possible to add a class such as .active then apply styles that way, but JW7 has extensive CSS Skin documentation. I styled the skin using the technique detailed here:
