Disney+: remember the volume level
Saves the volume level you set and restores it for every video you play next.
Code to copy
// Remember the player volume and restore it for every new video
function bindVolume(v) {
if (v.dataset.jzVol) { return; }
v.dataset.jzVol = '1';
var saved = parseFloat(localStorage.getItem('jz-dpl-volume'));
if (!isNaN(saved)) { v.volume = saved; }
v.addEventListener('volumechange', function () {
if (!v.muted) { localStorage.setItem('jz-dpl-volume', String(v.volume)); }
});
}
document.querySelectorAll('video').forEach(bindVolume);
var volObs = new MutationObserver(function () {
document.querySelectorAll('video').forEach(bindVolume);
});
volObs.observe(document.documentElement, { childList: true, subtree: true });How to use this example
