The question is variable scope in chrome extension. But i also want information for scope between background page and content scripts

I have a background html and a content script

I have declared a global variable in the start of background page say for example seltext

The content script is listening for mouse up events and in that code i want to update seltext

If this is not possible then i am planning to send seltext value from content script to background page by using sendresponse or i can use local storage. I hope the later will be taking more resources.

Since i am not having an clear picture of chrome extension working completely i am having this doubt.

Any type of response could be helpful.

A partial of what i wanted can be found here

yet detailed information reference about variable scope in chrome extension would be nice.

Context isn't shared between the background page and content script. sendRequest is the way to go.

You can set a setter and a getter for seltext in background page and use chrome-rpc in content scripts to call seltext's setter and getter for accessing seltext.
