Wie implementiert Imperial CMS das Hinzufügen zu Favoriten und das Festlegen als Startseite?

<a onclick="SetHome(window.location)" href="javascript：void(0)">设为首页</a></p> <p><a onclick="AddFavorite(window.location,document.title)" href="javascript：void(0)">加入收藏</a>

<script type="text/javascript" language="javascript"> 
function AddFavorite(sURL, sTitle) { 
sURL = encodeURI(sURL); 
try{ 
window.external.addFavorite(sURL, sTitle); 
}catch(e) { 
try{ 
window.sidebar.addPanel(sTitle, sURL, ""); 
}catch (e) { 
alert("加入收藏失败，请使用Ctrl+D进行添加,或手动在浏览器里进行设置."); 
} 
} 
} 
//设为首页 
function SetHome(url){ 
if (document.all) { 
document.body.style.behavior=&#39;url(#default#homepage)&#39;; 
document.body.setHomePage(url); 
}else{
alert("您好,您的浏览器不支持自动设置页面为首页功能,请您手动在浏览器里设置该页面为首页!"); 
} 
} 
</script>
