问题
Say I have an array of time in seconds.
var points = [5, 30, 50];
So when the jw player is initialized, I want to read this array and then place cue points[markers] on the timeline.
And once the seek bar reaches the cue point, I want to call a custom function that performs something.
The documentation of Jw is very plain but I found this - Adding chapter markers
I need something similar to this with full control on the cue points.
Is there any way to achieve this or should I use a custom control bar?
回答1:
I implemented the same thing by pausing the video on certain points. When paused, the user can only resume the video by clicking on a link (the controls are removed when paused).
I have the following HTML where the player and the cue points HTML are placed:
<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>
And the following 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);
});
});
