pageAction.show()
Shows the pageAction
for a given tab
. The page action is shown whenever the given tab is the active tab.
show()
overrides pattern matching, so the page action will be shown in the specified tab even if show_matches
does not match the URL or hide_matches
does.
Note that calling show()
has no effect on a tab with no content loaded.
Syntax
js
browser.pageAction.show(
tabId // integer
)
Parameters
Return value
A Promise
that will be fulfilled with undefined
.
Browser compatibility
BCD tables only load in the browser
Examples
This example shows the pageAction
for the active tab when the user selects a context menu item.
Note: You'll need the contextMenus
permission in your manifest to create context menu items.
js
browser.contextMenus.create({
id: "show",
title: "Show page action",
});
browser.contextMenus.onClicked.addListener((info, tab) => {
if (info.menuItemId === "show") {
browser.pageAction.show(tab.id);
}
});
