Fired when a new window, or a new tab in an existing window, is created to host the target of a navigation. For example, this event is sent when:
window.open()
(but note that the event is not sent if the browser's popup blocker blocks the load).
The event is not sent if a tab or window is created without a navigation target (for example, if the user opens a new tab by pressing Ctrl+T ).
If this event is fired, it will be fired before
webNavigation.onBeforeNavigate
.
browser.webNavigation.onCreatedNavigationTarget.addListener(
listener
,
// function
filter
// optional object
)

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)
校验是否
listener
is registered for this event. Returns
true
if it is listening,
false
否则。
callback
Function that will be called when this event occurs. The function will be passed the following arguments:
filter
可选
对象
. An object containing a single property
url
, which is an
数组
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.
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.
sourceProcessId
integer
. The ID of the process from which the navigation is initiated.
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.
tabId
integer
. The ID of the newly created tab.
timeStamp
编号
. The time when the browser created the navigation target, in
milliseconds since the epoch
.
url
string
. The URL which will be loaded in the new tab.
windowId
编号
. The ID of the window in which the new tab is created.
BCD tables only load in the browser
Logs the target URL, source Tab ID, and source frame ID for
onCreatedNavigationTarget
, if the target's hostname contains "example.com" or starts with "developer".
const filter = {
url:
[
{hostContains: "example.com"},
{hostPrefix: "developer"}
]
}
function logOnCreatedNavigationTarget(details) {
console.log(`onCreatedNavigationTarget: ${details.url}`);
console.log(details.sourceTabId);
console.log(details.sourceFrameId);
}
browser.webNavigation.onCreatedNavigationTarget.addListener(logOnCreatedNavigationTarget, filter);
