I just set up JW Player instance on a WordPress page. I wanted to re-create the functionality found here at https://developer.jwplayer.com/jw-player/demos/advanced/minimize-and-float-video-on-scroll/ where the player moves to the left or right side of the page and scrolls with the user. I have entered in the code given from JW Player as follows:
<div id="float-video-player" class="player-container"></div>
<!-------------------------- JW Player Float and scroll ----------------------------->
<script type="text/javascript">
// initialize jwplayer
var playerInstance = jwplayer('float-video-player');
// player dom elements
var playerContainerEl = document.querySelector('.player-container');
// returns video player position from top of document
function getElementOffsetTop(el) {
var boundingClientRect = el.getBoundingClientRect();
var bodyEl = document.body;
var docEl = document.documentElement;
var scrollTop = window.pageYOffset || docEl.scrollTop || bodyEl.scrollTop;
var clientTop = docEl.clientTop || bodyEl.clientTop || 0;
return Math.round(boundingClientRect.top + scrollTop - clientTop);
}
// returns the current y scroll position
function getScrollTop() {
var docEl = document.documentElement;
return (window.pageYOffset || docEl.scrollTop) - (docEl.clientTop || 0);
}
// configure jwplayer instance
playerInstance.setup({
autostart: true,
file: 'https://cdn.jwplayer.com/players/jgjfjfj',
primary: 'html5',
setFullscreen: true,
width: '100%'
});
// when jwplayer instance is ready
playerInstance.on('ready', function() {
var config = playerInstance.getConfig();
var utils = playerInstance.utils;
// get height of player element
var playerHeight = config.containerHeight;
// get player element position from top of document
var playerOffsetTop = getElementOffsetTop(playerContainerEl);
// set player container to match height of actual video element
// this prevents container from disappearing and changing element positions
// on page when player becomes minimized. this also leaves a nice visual
// placeholder space for minimized player to return to when appropriate
playerContainerEl.style.height = playerHeight + 'px';
// below we handle window scroll event without killing performance
// this is a minimal approach. please consider implementing something more extensive:
// i.e. http://joji.me/en-us/blog/how-to-develop-high-performance-onscroll-event
// determine player display when scroll event is called
// if inline player is no longer visible in viewport, add class
// .player-minimize to minimize and float. otherwise, remove the class to put
// player back to inline inline position
function onScrollViewHandler() {
var minimize = getScrollTop() >= playerOffsetTop;
utils.toggleClass(playerContainerEl, 'player-minimize', minimize);
// update the player's size so the controls are adjusted
playerInstance.resize();
}
// namespace for whether or not we are waiting for setTimeout() to finish
var isScrollTimeout = false;
// window onscroll event handler
window.onscroll = function() {
// skip if we're waiting on a scroll update timeout to finish
if (isScrollTimeout) return;
// flag that a new timeout will begin
isScrollTimeout = true;
// otherwise, call scroll event view handler
onScrollViewHandler();
// set new timeout
setTimeout(function() {
// reset timeout flag to false (no longer waiting)
isScrollTimeout = false;
}, 80);
};
});
</script>
So when I push the code to the site, the player is there, but the intended functionality doesn't work, is there something missing?
