更改视频时如何释放内存？

Question

当源改变时，如何释放用于存储视频的内存：

var video = document.querySelector('.video');
var nextButton = document.getElementById('next-button');
nextButton.addEventListener('click', function() {
    video.src = videoQueue.shift();
});

Answer 1

var video = document.querySelector('.video');
var nextButton = document.getElementById('next-button');
nextButton.addEventListener('click', function() {
    video.removeAttribute("src");//This will clear memory
    video.load();//Refresh
});

我希望这会有所帮助。
