Removes a menu item.
For compatibility with other browsers, Firefox makes this method available via the
contextMenus
namespace as well as the
menus
名称空间。
This is an asynchronous function that returns a
Promise
.
var removing = browser.menus.remove(
menuItemId
// integer or string
)
menuItemId
integer
or
string
. The ID of the menu item to remove.
A
Promise
that will be fulfilled with no arguments if removal was successful, or rejected with an error message if removal failed (for example, because the item could not be found).
This extension adds a menu item labeled "Remove me!". If you click the item, the extension removes it.
function onRemoved() {
console.log("item removed successfully");
}
function onError() {
console.log("error removing item:" + browser.runtime.lastError);
}
browser.menus.create({
id: "remove-me",
title: "Remove me!",
contexts: ["all"]
});
browser.menus.onClicked.addListener(function(info, tab) {
if (info.menuItemId == "remove-me") {
var removing = browser.menus.remove(info.menuItemId);
removing.then(onRemoved, onError);
}
});
