webNavigation.onCreatedNavigationTarget

Fired when a new window, or a new tab in an existing window, is created to host a navigation: for example, if the user opens a link in a new tab.

If this event is fired, it will be fired before webNavigation.onBeforeNavigate.

Syntax

chrome.webNavigation.onCreatedNavigationTarget.addListener(
  function(details) {...}     // function
  filter                      // optional object 
)
chrome.webNavigation.onCreatedNavigationTarget.removeListener(listener)
chrome.webNavigation.onCreatedNavigationTarget.hasListener(listener)

This API is also available as browser.webNavigation.onCreatedNavigationTarget.*.

Events have three functions:

addListener(callback)

Adds a listener to this event.

removeListener(listener)

Stop listening to this event. The listener argument is the listener to remove.

hasListener(listener)

Check whether listener is registered for this event. Returns true if it is listening, false otherwise.

addListener syntax

Parameters

callback

Function that will be called when this event occurs. The function will be passed the following arguments:

details

object. Details about the navigation event.

filterOptional

object. An object containing a single property url, which is an Array of events.UrlFilter objects. If you include this parameter, then the event will fire only for transitions to URLs which match at least one UrlFilter in the array. If you omit this parameter, the event will fire for all transitions. Note that filter is not supported in Firefox.

Additional objects

details

sourceTabId

integer. The ID of the tab from which the navigation is initiated. For example, if the user opens a link in a new tab, this will be the ID of the tab containing the link.

url

string. The URL to which the new frame will navigate.

sourceProcessId

integer. The ID of the process from which the navigation is initiated.

sourceFrameId

integer. ID of the frame from which the navigation is initiated. 0 indicates that the frame is the tab's top-level browsing context, not a nested iframe. A positive value indicates that navigation is initiated from a nested iframe. Frame IDs are unique for a given tab and process.

timeStamp

number. The time when the browser created the navigation target, in milliseconds since the epoch.
