webNavigation.getAllFrames()

Given a tab ID, retrieves information about all the frames it contains.

This is an asynchronous function that returns a Promise.

Syntax

var gettingFrames = browser.webNavigation.getAllFrames(
  details                // object
)

Parameters

details

object. Information about the tab to retrieve all frames from.

tabId

integer. The ID of the tab.

Return value

A Promise that will be fulfilled with an array of objects, each of which has the following properties:

errorOccurred

boolean. True if the last navigation in this frame was interrupted by an error, i.e. the onErrorOccurred event fired.

processId

integer. The ID of the process running the renderer for this tab.

frameId

integer. The ID of the frame. If this is the main frame, then frameId is zero.

parentFrameId

integer. ID of this frame's parent. This is -1 if there is no parent frame: that is, if this frame is the top-level browsing context in the tab.

url

string. The URL currently associated with this frame.

If the specified tab could not be found, or some other error occurs, the promise will be rejected with an error message.

Browser compatibility

Examples

This code logs the URLs of all frames in the active tab, when the user clicks a browser action:

function logFrameInfo(framesInfo) {
  for (frameInfo of framesInfo) {
    console.log(frameInfo);
  }
}

function onError(error) {
  console.log(`Error: ${error}`);
}

function logAllFrames(tabs) {
  var gettingAllFrames = browser.webNavigation.getAllFrames({tabId: tabs[0].id});
  gettingAllFrames.then(logFrameInfo, onError);
}

browser.browserAction.onClicked.addListener(function() {

  var querying = browser.tabs.query({
    currentWindow: true,
    active: true
  });

  querying.then(logAllFrames, onError);

});
