Fired when a page action icon is clicked. This event will not fire if the page action has a popup.
To define a right-click action, use the
contextMenus
API with the "page_action"
context type
.
browser.pageAction.onClicked.addListener(listener)

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)
Checks whether a
listener
is registered for this event. Returns
true
if it is listening,
false
否则。
BCD tables only load in the browser
callback
A function that will be called when this event occurs. The function is passed the following arguments:
tab
A
tabs.Tab
object representing the tab whose page action was clicked.
OnClickData
An object containing information about the click.
modifiers
An
array
. The keyboard modifiers active at the time of the click, being one or more of
Shift
,
Alt
,
命令
,
Ctrl
，或
MacCtrl
.
button
An
integer
. Indicates the button used to click the page action icon:
0
for a left-click or a click not associated with a mouse, such as one from the keyboard and
1
for a middle button or wheel click. Note that the right-click is not supported because Firefox consumes that click to display the context menu before this event is triggered.
When the user clicks the page action, hide it, and navigate the active tab to " https://giphy.com/explore/cat ":
var CATGIFS = "https://giphy.com/explore/cat";
browser.pageAction.onClicked.addListener((tab) => {
browser.pageAction.hide(tab.id);
browser.tabs.update({url: CATGIFS});
});
browser.pageAction.onClicked.addListener(function () {
});
