How to build a HTML 5 video playlist?_问答_开发者

Hi< I was wondering would anybody know of tutorials describ开发者_开发知识库ing, in detail, how to build a video playlist in HTML 5? I also would like these videos to play in a random order.

I created a JS fiddle for this here:

http://jsfiddle.net/Barzi/Jzs6B/9/

First, your HTML markup looks like this:

<video id="videoarea" controls="controls" poster="" src=""></video>

<ul id="playlist">
    <li movieurl="VideoURL1.webm" moviesposter="VideoPoster1.jpg">First video</li>
    <li movieurl="VideoURL2.webm">Second video</li>
    ...
    ...
</ul>

Second, your JavaScript code via JQuery library will look like this:

$(function() {
    $("#playlist li").on("click", function() {
        $("#videoarea").attr({
            "src": $(this).attr("movieurl"),
            "poster": "",
            "autoplay": "autoplay"
        })
    })
    $("#videoarea").attr({
        "src": $("#playlist li").eq(0).attr("movieurl"),
        "poster": $("#playlist li").eq(0).attr("moviesposter")
    })
})

And last but not least, your CSS:

#playlist {
    display:table;
}
#playlist li{
    cursor:pointer;
    padding:8px;
}
#playlist li:hover{
    color:blue;                        
}
#videoarea {
    float:left;
    width:640px;
    height:480px;
    margin:10px;    
    border:1px solid silver;
}

You can use this. perfect and easily.

            width:640px;

        }

            }
            var container = document.getElementById('button_container');
            var buttons = container.getElementsByTagName('div');
            for(var i = 0; i < buttons.length; i++){
                buttons[i].setAttribute('onclick', 'update_source(this.id)');

To directly answer the question without any frameworks or CSS:

<!DOCTYPE html>
<html lang="en">
    <head></head>
    <body>
        <select class="form-control" id="videoSelection"
            onchange="updateSource(this.value);"
        >
            <option>file1.mp4</option>
            <option>file2.mp4</option>
            <option>file3.mp4</option>
            <option>file4.mp4</option>
            <option>file5.mp4</option>
    </select>
        <br />
        <video allowfullscreen controls autoplay muted id="video">
        </video>
        <script type="text/javascript">
            function updateSource(currentSource) {
                var videoSources = document.getElementById('videoSelection').options;
                var nextSource = videoSources[Math.floor(Math.random() * videoSources.length)].text;
                for (var i = 0; i < videoSources.length - 1; i++) {
                    if (videoSources[i].text == currentSource) {
                        break;
                    }
                }
                videoSources[i].selected = true;
                document.getElementById('video').src = currentSource;
                document.getElementById('video').onended = function() {updateSource(nextSource)};
            }
        </script>
    </body>
</html>

Just define the files in the select. Choose a file when the page loads and it will randomly select the next video from the available options.
