JavaScript 实现多浏览器兼容的设为首页与加入收藏功能

多浏览器兼容的设为首页与加入收藏代码实现

代码实现如下：

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>无标题页</title>
<script language="javascript" type="text/javascript">
function AddFavorite(sURL, sTitle)
{ 
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");
} 
} 
} 
function SetHome(obj,vrl){
try{
obj.style.behavior='url(#default#homepage)';obj.setHomePage(vrl);
} 
catch(e){
if(window.netscape) {
try {
netscape.security.PrivilegeManager.enablePrivilege("UniversalXPCONNECT");
} 
catch (e) {
alert("此操作被浏览器拒绝！\n请在浏览器地址栏输入“about:config”并回车\n然后将 [signed.applets.codebase_principal_support]的值设置为'true',双击即可。");
} 
var prefs = Components.classes['@mozilla.org/preferences-service;1'].getService(Components.interfaces.nsIPrefBranch);
prefs.setCharPref('browser.startup.homepage',vrl);
} 
} 
} 
</script>
</head>
<body>
<form id="form1" runat="server">
<a onclick="AddFavorite(window.location,document.title)" style="cursor:pointer">加入收藏</a>
<a onclick="SetHome(this,window.location)" style="cursor:pointer">设为首页</a>
</form>
</body>
</html>
