tabs.sendRequest()

This method has been deprecated. Use tabs.sendMessage() instead.

Sends a single request to the content script(s) in the specified tab, with an optional callback to run when a response is sent back. The extension.onRequest event is fired in each content script running in the specified tab for the current extension.

This is an asynchronous function that returns a Promise.

Syntax

var sending = browser.tabs.sendRequest(
  tabId,                   // integer
  request                  // any
)

Parameters

tabId
integer.
request
any.

Return value

A Promise that will be fulfilled with the JSON response object sent by the handler of the message in the content script, or with no arguments if the content script did not send a response. If an error occurs while connecting to the specified tab or any other error occurs, the promise will be rejected with an error message.
