兼容 IE 火狐设为首页 加入收藏 当前地址 js代码
<html><head>
<script type="text/javascript">
function addFav(){ // 加入收藏夹
if (document.all) {
window.external.addFavorite(window.location.href, document.title);
} else if (window.sidebar) {
window.sidebar.addPanel(document.title, window.location.href, "");
}
}
function setHomepage(){ // 设置首页
if (document.all) {
document.body.style.behavior = 'url(#default#homepage)';
document.body.setHomePage(window.location.href);
} else if (window.sidebar) {
if () {
try {
netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
} catch(e) {
alert("该操作被浏览器拒绝，如果想启用该功能，请在地址栏内输入 about:config,然后将项 signed.applets.codebase_principal_support 值该为true");
}
}
var prefs = Components.classes['@'].getService(Components.interfaces.nsIPrefBranch);
prefs.setCharPref('browser.startup.homepage', window.location.href);
}
}
</script>
</head>
<body>
<a href ="javascript:void(0)" onclick ="setHomepage()"> 设为首页 </a>
<a href="javascript:void(0)" onclick ="addFav()"> 加入收藏 </a>
</body>
</html>
这段代码为什么设为首业不兼容火狐 其他的都正确
