Is it possible to copy an image to the clipboard in javascript? I know how to copy text, but can you copy images?
Is it a security limitation?
回答1:
No, you can't copy images to the clipboard. Copying anything to the clipboard is a security limitation of every browser, but you may able to copy text to the clipboard in IE if they have the proper security settings. Here Mozilla lists some of the problems caused by programmatic access to the clipboard.
回答2:
Yes, most of the scripts supports text only.

The above site also discussing the same issue.
