Thor,
Creio que queres qualquer coisa deste tipo:
<a href="http://Location/Of/Bookmark/Page" title="Bookmark Title" rel="sidebar" onclick="
if( window.sidebar && window.sidebar.addPanel ) {
//Gecko (Netscape 6 etc.) - add to Sidebar
window.sidebar.addPanel( this.title, this.href, '' );
} else if( window.external && ( navigator.platform == 'Win32' ||
( window.ScriptEngine && ScriptEngine().indexOf('InScript') + 1 ) ) ) {
//IE Win32 or iCab - checking for AddFavorite produces errors for no
//good reason, so I use a platform and browser detect.
//adds the current page page as a favourite; if this is unwanted,
//simply write the desired page in here instead of 'location.href'
window.external.AddFavorite( location.href, document.title );
} else if( window.opera && window.print ) {
//Opera 6+ - add as sidebar panel to Hotlist
return true;
} else if( document.layers ) {
//NS4 & Escape - tell them how to add a bookmark quickly (adds current page,
//not target page)
window.alert( 'Please click OK then press Ctrl+D to create a bookmark' );
} else {
//other browsers - tell them to add a bookmark (adds current page, not target page)
window.alert( 'Please use your browser\'s bookmarking facility to create a bookmark' );
}
return false;
">Add to Favorites, Bookmarks, Sidebar or Hotlist</a>
