how to get a callback using chrome.tabs.executeScript

[キューゾ リファイ]

Hello, I'm trying to execute a script on a tab from background.html,
but I don't know how to make the tab respond to my script.
I tried console.log() but failed.

Any suggestions please.

Hey there,

When you call the executeScript, the callback for that function gets fired when the JavaScript has been executed. To get a response back, you would need to use extension Message Passing to pass the message from the content script (that gets executed) to your background/popup/options/etc page that initiated that executeScript call.

For more information regarding Message Passing, the docs has a good set of examples:

Kind regards,
