JavaScript加载图像的进度 [英] JavaScript loading progress of an image

问题描述

有没有一种方法可以让JS在加载图像时获取加载图像的进度？
我想使用HTML5的新Progress标签来显示加载图片的进度。

Is there a way in JS to get the progress of a loading image while the image is being loaded? I want to use the new Progress tag of HTML5 to show the progress of loading images.

我希望有这样的内容：

var someImage = new Image()
someImage.onloadprogress = function(e) { progressBar.value = e.loaded / e.total };
someImage.src = "image.jpg";
