源码搜藏网

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″><p><!－－</p><p>var username = getcookie(′username′);</p><p>if (username == null) {</p><p>username = prompt(′please enter your name (otherwise press cancel)′,″″);</p><p>if (username == null) {</p><p>alert(′its ok if you dont want to tell me your name′);</p><p>username = ′websurfer′;</p><p>} else {</p><p>// don′t set the username cookie.... because the user refused to tell you.</p><p>// they will be prompted next time....</p><p>pathname = location.pathname;</p><p>mydomain = pathname.substring(0,pathname.lastindexof(′/′)) ＋′/′;</p><p>// set expiry date to 1 year from now.</p><p>var largeexpdate = new date ();</p><p>largeexpdate.settime(largeexpdate.gettime()＋(365＊24＊3600＊1000));</p><p>setcookie(′username′,username,largeexpdate,mydomain); } }</p><p>function getcookieval (offset) {</p><p>var endstr = document.cookie.indexof (″;″, offset);</p><p>if (endstr == －1)</p><p>endstr = document.cookie.length;</p><p>return unescape(document.cookie.substring(offset, endstr)); }</p><p>function getcookie (name) {</p><p>var arg = name ＋ ″=″;</p><p>var alen = arg.length;</p><p>var clen = document.cookie.length;</p><p>var i = 0;</p><p>while (i < clen) {</p><p>var j = i ＋ alen;</p><p>if (document.cookie.substring(i, j)==arg)</p><p>return getcookieval (j);</p><p>i = document.cookie.indexof(″ ″, i) ＋ 1;</p><p>if (i == 0)</p><p>break;</p><p>} return null; }</p><p>function setcookie (name, value) {</p><p>var argv = setcookie.arguments;</p><p>var argc = setcookie.arguments.length;</p><p>var expires = (argc > 2) argv[2] : null;</p><p>var path = (argc > 3) argv[3] : null;</p><p>var domain = (argc > 4) argv[4] : null;</p><p>var secure = (argc > 5) argv[5] : false;</p><p>document.cookie = name ＋ ″=″ ＋ escape (value)＋((expires == null) ″″ : (″; expires=″＋expires.togmtstring()))＋((path == null) ″″ : (″; path=″ ＋ path))＋((domain == null) ″″ : (″; domain=″ ＋ domain))＋((secure == true) ″; secure″ : ″″);</p><p>}</p><p>document.write(′<p>谢谢您的光临, ′＋username);</p><p>//－－></script></p>

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。
