image dump from print screen

How would you dump an image captured using the print sreen key into a div开发者_运维知识库 tag?

You can't. Best way to do something like this is using a Java applet or ActiveX component.

clipboardData is available on IE, but doesn't support access to images. It is not supported by default in Firefox.

I just tried creating a screen shot using print screen and inserting it to a rich HTML field in Firefox. It pastes an IMG tag with a link to a local temporary file (moz-screenshot.png). So in the local context (your own computer), it seems possible, but you are going to have a very hard time getting that local file to your server. Maybe with a tweaked Flash upload component.

Short answer: You can't.

Now, that said, if you are using Javascript inside of an HTA file, you should read this thread: Take a screenshot of a webpage with JavaScript?

Hope this helps.
