Gets an array containing information about pages that the user has visited often and recently.
Browsers keep a list of pages that the user visits often and recently. They use this list to help the user get back to these places easily. For example, Firefox by default provides a list of the most-visited pages in the "New Tab" page.
To determine which pages appear in the list, and the order in which they appear, the browser combines "frequency" - how often the user has visited the page - and "recency" - how recently the user visited the page.
The browser may then apply further filtering to this list before presenting it to the user. For example, in Firefox the "New Tab" page only lists one page per domain, and the user is able to block pages from appearing in the list.
topSites.get()
API enables an extension to get access to this list. Called without any options, it will provide the filtered list of pages - that is, the one that appears in the "New Tab" page. However, by providing various options it's possible for an extension to get the unfiltered list of pages.
This is an asynchronous function that returns a
Promise
.
To use the topSites API you must have the "topSites" API permission .
var gettingTopSites = browser.topSites.get(
options // object
)

BCD tables only load in the browser
This code logs the title and URL for all pages in the "New Tab" page:
function logTopSites(topSitesArray) {
for (topSite of topSitesArray) {
console.log(`Title: ${topSite.title}, URL: ${topSite.url}`);
}
}
function onError(error) {
console.log(error);
}
var gettingTopSites = browser.topSites.get();
gettingTopSites.then(logTopSites, onError);
This code logs the title and URL for all top pages, including ones the user has blocked, and potentially including multiple pages in the same domain:
function logTopSites(topSitesArray) {
for (topSite of topSitesArray) {
console.log(`Title: ${topSite.title}, URL: ${topSite.url}`);
}
}
function onError(error) {
console.log(error);
}
var gettingTopSites = browser.topSites.get({
includeBlocked: true,
onePerDomain: false
});
gettingTopSites.then(logTopSites, onError);
注意：
This API is based on Chromium's
chrome.topSites
API。
