history.onVisited 编辑

Fired each time the user visits a page. A history.HistoryItem object is passed to the listener. This event fires before the page has loaded.

Syntax

browser.history.onVisited.addListener(listener)
browser.history.onVisited.removeListener(listener)
browser.history.onVisited.hasListener(listener)

Events have three functions:

addListener(callback)

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:

result

history.HistoryItem. An object representing the item in the browser's history.

At the time that this event is sent, the browser doesn't yet know the title of the page. If the browser has visited this page before and has remembered its old title, then the HistoryItem.title object will contain the old title of the page. If the browser doesn't have a record of the page's old title, then HistoryItem.title will be empty. To get the titles of pages as soon as they are known, listen for history.onTitleChanged.
