一个可以兼容IE FF的加为首页与加入收藏实现代码

代码如下:
<script type="text/javascript">
function addCookie()
{
if (document.all)
{
window.external.addFavorite('//www.gxlcms.com','脚本之家');
}
else if (window.sidebar)
{
window.sidebar.addPanel('脚本之家', '//www.gxlcms.com', "");
}
}

function setHomepage()
{
if (document.all)
{
document.body.style.behavior='url(#default#homepage)';
document.body.setHomePage('//www.gxlcms.com');

}
else if (window.sidebar)
{
if(window.netscape)
{
try
{
netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
}
catch (e)
{

}
}
var prefs = Components.classes['@mozilla.org/preferences-service;1'].getService(Components. interfaces.nsIPrefBranch);
prefs.setCharPref('browser.startup.homepage','//www.gxlcms.com');
}
}
</script>

<form>
<a href="#" onclick="return setHomepage();">设为首页</a>
<a href="#" onclick="return addCookie();">添加收藏</a>
</form>
