巧用JS程序,制作有趣的网站提醒

     如果你经常上网的话,也许大家在许多地方都会看到在网页的上方看到“发现您正在使用老掉牙的IE浏览器,强烈推荐您在Windows 操作系统中使用最安全的浏览器:FireFox火狐浏览器2.0,点击下载!”这样的话,今天就给大家说说它的做法。  不过说实话,你点了下了装了,你就给别人赚钱了。。。自己想吧
     写一个JS程序调用就可以了。然后首页调用
        <script src="http://www.你的域名.com/FireFox.js" type="text/javascript"></script>

下面是JS文件内容,修改下域名就行。要美观的话就补充两个小图片。

 

function writeCookie(name, value, hours)
 {
 var expire = "";
 if(hours != null)
 {
 expire = new Date((new Date()).getTime() + hours * 3600000);
 expire = "; expires=" + expire.toGMTString();
 }
 document.cookie = name + "=" + escape(value) + expire;
 }
 
 // Example:
 // alert( readCookie("myCookie") );
 function readCookie(name)
 {
 var cookieValue = "";
 var search = name + "=";
 if(document.cookie.length > 0)
 {
 offset = document.cookie.indexOf(search);
 if (offset != -1)
 {
 offset += search.length;
 end = document.cookie.indexOf(";", offset);
 if (end == -1) end = document.cookie.length;
 cookieValue = unescape(document.cookie.substring(offset, end))
 }
 }
 return cookieValue;
 }

 if(readCookie("status") != "showed24")
 {
 hasIE_hideAndShow();
 }
