selection-to-clipboard

What it does

This extension includes:

• a content script, "content-script.js", that is injected into all pages

The content script listens for text selections in the page it's attached to and copies the text to the clipboard on mouse-up.

What it shows

• how to inject content scripts declaratively using manifest.json
• how to write to the clipboard

Note

• If the copySelection function was in a browser event clipboardWrite permissions would be required e.g.

"permissions": ["clipboardWrite"]
