假设我有几秒钟的时间。

var points = [5, 30, 50];

因此,当jw播放器初始化时,我想读取此数组,然后在时间轴上放置提示点[markers]。

一旦搜寻栏到达提示点,我想调用一个执行某些功能的自定义函数。

Jw的文档非常简单,但是我发现了这一点-Adding chapter markers

我需要与此类似的东西并完全控制提示点。

有什么方法可以做到这一点,还是应该使用自定义控件栏?

最佳答案

我通过在某些地方暂停视频来实现相同的目的。暂停时,用户只能通过单击链接来恢复视频(暂停时控件将被删除)。

我有以下放置播放器和提示点HTML的HTML:

<div class="row">
    <div class="col-xs-12 col-md-5">
        <div id="myElement">Loading the player...</div>
    </div>
    <div class="col-xs-12 col-md-7">
        <div id="on10seconds" class="hidden">
            <p>Show after 10 seconds. <a href="#" class="positionInfoLink" data-position="10">Continue...</a></p>
        </div>
        <div id="on25seconds" class="hidden">
            <p>Show after 25 seconds. <a href="#" class="positionInfoLink" data-position="25">Continue...</a></p>
        </div>
        <div id="on50seconds" class="hidden">
            <p>Show after 50 seconds. <a href="#" class="positionInfoLink" data-position="50">Continue...</a></p>
        </div>
    </div>
</div>

以及以下JavaScript:
var positions = [10, 25, 50];
var positionsSeen = [];

var player = jwplayer("myElement").setup({
    file: "/Content/videos/big_buck_bunny.mp4"
});
player.onTime(jwPlayerOnTime);

function jwPlayerOnTime(onTimeInfo) {
    var currentPosition = onTimeInfo.position;
    for (var i = 0; i < positions.length; i++) {
        var position = positions[i];
        var isPositionSeen = positionsSeen.indexOf(position) != -1;
        // Within 2 seconds, so users can't skip to see the extra information displayed when pausing.
        var isOnOrPastPosition = currentPosition > position && currentPosition <= position + 2;

        if (isPositionSeen == false && isOnOrPastPosition) {
            positionsSeen.push(position);
            player.pause(true);
            // Disable the controls, so the video can only be resumed with the custom controls.
            player.setControls(false);
            $("#on" + position + "seconds").removeClass("hidden");
        }
    }
}

$(document).ready(function () {
    $(".positionInfoLink").on("click", function (e) {
        e.preventDefault();
        var position = $(this).data("position"); // 10, 25 or 50.
        $(this).parent().addClass("hidden");
        player.play(true);
        // Enable the controls, so the video can be paused manually again.
        player.setControls(true);
    });
});
