webNavigation.onDOMContentLoaded

Fired when the DOMContentLoaded event is fired in the page. At this point the document is loaded and parsed, and the DOM is fully constructed, but linked resources such as images, stylesheets and subframes may not yet be loaded.

Syntax

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

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

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.

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

tabId

integer. The ID of the tab in which the navigation has occurred.

url

string. The URL to which the given frame has navigated.

processId

integer. The ID of the process in which this tab is being rendered.

frameId

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

timeStamp

number. The time at which DOMContentLoaded was fired, in milliseconds since the epoch.
