这个需要HTML5中的File API功能吧? IE8多半是支持不了:

<code>document.onpaste = function(event){
  var items = event.clipboardData.items;
  for (index in items) {
    var item = items[index];
    if (item.kind === 'file') {
      var blob = item.getAsFile();
      var reader = new FileReader();
      reader.onload = function(evt){
         console.log(evt.target.result)
      };
      reader.readAsDataURL(blob);
  }
}
</code>
Copy after login

不过!!!!不要误以为可以直接复制一个图片文件然后粘贴,一个图片文件和你按PrntScr键或者在windows画图中复制的图片内容是两码事!!!
