Use this API to register content scripts. Registering a content script instructs the browser to insert the given content scripts into pages that match the given URL patterns.
This API is very similar to the
"content_scripts" manifest.json key, except that with
"content_scripts" , the set of content scripts and associated patterns is fixed at install time. With the
contentScripts API, an extension can register and unregister scripts at runtime.
To use the API, call
contentScripts.register() passing in an object defining the scripts to register, the URL patterns, and other options. This returns a
Promise that is resolved with a
contentScripts.RegisteredContentScript object. The
RegisteredContentScript object represents the scripts that were registered in the
register() call. It defines an
unregister() method that you can use to unregister the content scripts.
There is no
contentScripts API permission, but an extension must have the appropriate host permissions for any patterns it passes to
An object of this type is returned by the
contentScripts.register()function. It represents the content scripts that were registered by that call, and can be used to unregister the content script.
- Registers the given content scripts.
