另一种选择是通过在内存中创建图像元素来触发 onload 和/或 onerror 事件并将其 src 属性设置为原始图像的原始 src 属性.这是我的意思的一个例子:

Another option is to trigger the onload and/or onerror events by creating an in memory image element and setting its src attribute to the original src attribute of the original image. Here's an example of what I mean:

$("<img/>")
    .on('load', function() { console.log("image loaded correctly"); })
    .on('error', function() { console.log("error loading image"); })
    .attr("src", $(originalImage).attr("src"))
;

希望这有帮助！
