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：

<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。
