Bookmarklet
open-in-new
<p>A bookmarklet is a <a href="/facts/Bookmark_(digital)/E4WpX0Ku">bookmark</a> stored in a <a href="/facts/Web_browser/2pfyymLs">web browser</a> that contains JavaScript commands that add new features to the browser. They are stored as the <a href="/facts/Uniform_Resource_Locator/pPD5g7Wq">URL</a> of a bookmark in a <a href="/facts/Web_browser/2pfyymLs">web browser</a> or as a <a href="/facts/Hyperlink/LqNsa84e">hyperlink</a> on a <a href="/facts/Web_page/5JK7xQLe">web page</a>. Bookmarklets are usually small snippets of <a href="/facts/JavaScript/XhhIIEsl">JavaScript</a> executed when user clicks on them. When clicked, bookmarklets can perform a wide variety of operations, such as running a search query from selected text or extracting data from a table. </p><p>Another name for <i>bookmarklet</i> is favelet or favlet, derived from <i>favorites</i> (synonym of bookmark). </p>
