添加收藏夹
首先是使用快捷键进行添加，如我们熟知的“Ctrl+D”，但是并不是说有的电脑都支持这么操作。键盘快捷键：Ctrl+D 仅适用于 Windows 和Linux）；⌘-D 才适用于苹果机（苹果机上没有Ctrl键）。
方案一：使用Javascript模拟键盘操作

如果嫌上面的方案比较麻烦，可以采用jQuery来快速搞定。具体实现如下：

var evt = jQuery.Event("keypress");
evt.keyCode = 100; // d
evt.ctrlKey = true;
$(document).trigger(evt);
方案二：采用Javascript来添加书签
以下是一段能自动把当前页面添加到浏览器书签的JavaScript 脚本，支持 FireFox，Opera 和 IE，Webkit 核心的 Safari 和Chrome 暂时没有实现类似功能的方法。

function bookmark(url, title){
if (window.sidebar) // firefox
window.sidebar.addPanel(title, url, "");
else if(window.opera && window.print){ // opera
var elem = document.createElement('a');
elem.setAttribute('href',url);
elem.setAttribute('title',title);
elem.setAttribute('rel','sidebar');
elem.click();
}
else if(document.all) // ie
window.external.AddFavorite(url, title);
else
alert('Your browser does not support this function.');
}
同样的，也提供另外的jQuery方案：

$(document).ready(function(){
$("a.jQueryBookmark").click(function(e){
e.preventDefault(); // this will prevent the anchor tag from going the user off to the link
var bookmarkUrl = this.href;
var bookmarkTitle = this.title;
if (window.sidebar) { // For Mozilla Firefox Bookmark
window.sidebar.addPanel(bookmarkTitle, bookmarkUrl,"");
} else if( window.external || document.all) { // For IE Favorite
window.external.AddFavorite( bookmarkUrl, bookmarkTitle);
} else if(window.opera) { // For Opera Browsers
$("a.jQueryBookmark").attr("href",bookmarkUrl);
$("a.jQueryBookmark").attr("title",bookmarkTitle);
$("a.jQueryBookmark").attr("rel","sidebar");
} else { // for other browsers which does not support
alert('Your browser does not support this bookmark action');
return false;
}
});
});
