If you're in a real hurry, here is a gist.Making a Chrome Extension that Reads & Writes to the Clipboard The Clipboard History Pro extension helps to manage your clipboard history in a way that you never have to worry while copy-pasting again. In particular, background.html, background.js, and contentscript.js. If you want to see the above technique in practice, take a look at the code. I have an extension whose only purpose is to paste, and the architecture came largely from this post. The two scripts are able to communicate pretty easily with message passing. Any pasting or copying from the DOM of the page the user is viewing has to occur in your content script. This essentially means you need to do the copy/paste actions from the system clipboard in your event/background pages, which is what Alasdair has outlined above. Take a look at the explanation of the extension architecture for a good overview of all this. Content scripts cannot interact with the system clipboard, but they can interact with the DOM of pages the user has loaded. They are not able to interact with the DOM of pages the user has loaded. For anyone in a similar position, here is an expansion on his answer.īackground/event pages are able to interact with the system clipboard, provided you've requested the appropriate permissions. Alasdair's answer is excellent and worked great for me, but as a newcomer to Chrome extensions it still took me a while to get it working. This is too long for a comment on Alasdair's excellent response, so I'm creating another answer.
