增添靓丽风景 让网页记住你的姓名

　　大家有没有这样的想法呢？就是当我们在浏览某个站点或者是页面时，可以把浏览者的姓名给记录下来，这样可以为你的主页增添了一道靓丽的风景线。

　　实现方法：

　　一、在页面中添加如下的代码：

[code]<script language=″Javascript″>

<!－－

var username = getcookie(′username′);

if (username == null) {

username = prompt(′please enter your name (otherwise press cancel)′,″″);

if (username == null) {

alert(′its ok if you dont want to tell me your name′);

username = ′websurfer′;

} else {

// don′t set the username cookie.... because the user refused to tell you.

// they will be prompted next TIMe....

pathname = location.pathname;

mydomain = pathname.substring(0,pathname.lastindexof(′/′)) ＋′/′;

// set expiry date to 1 year from now.

var largeexpdate = new date ();

largeexpdate.settime(largeexpdate.gettime()＋(365＊24＊3600＊1000));

setcookie(′username′,username,largeexpdate,mydomain); } }

function getcookieval (offset) {

var endstr = document.cookie.indexof (″;″, offset);

if (endstr == －1)

endstr = document.cookie.length;

return unescape(document.cookie.substring(offset, endstr)); }

function getcookie (name) {

var arg = name ＋ ″=″;

var alen = arg.length;

var clen = document.cookie.length;

var i = 0;

while (i < clen) {

var j = i ＋ alen;

if (document.cookie.substring(i, j)==arg)

return getcookieval (j);

i = document.cookie.indexof(″ ″, i) ＋ 1;

if (i == 0)

break;

} return null; }

function setcookie (name, value) {

var argv = setcookie.arguments;

var argc = setcookie.arguments.length;

var expires = (argc > 2) ? argv[2] : null;

var path = (argc > 3) ? argv[3] : null;

var domain = (argc > 4) ? argv[4] : null;

var secure = (argc > 5) ? argv[5] : false;

document.cookie = name ＋ ″=″ ＋ escape (value)＋((expires == null) ? ″″ : (″; expires=″＋expires.togmtstring()))＋((path == null) ? ″″ : (″; path=″ ＋ path))＋((domain == null) ? ″″ : (″; domain=″ ＋ domain))＋((secure == true) ? ″; secure″ : ″″);

}

document.write(′<p>谢谢您的光临, ′＋username);

//－－></script>

　　当运行成功之后，会出现一个对话框，要求对方输入姓名，然后就会在网页中出现对方的姓名了。
