支付宝的kill-ie

支付宝首页改版了，新首页很漂亮，可是对于老版本IE用户怎么办，支付宝是这么做的！

1 <!--[if lte IE 7]>
2   <script type="text/javascript">
3     window.location.href = 'https://www.alipay.com/x/kill-ie.htm';
4   </script>
5 <![endif]-->

下面是支付宝用的css reset样式：

 1 /* reset样式 */
 2 
 3 html{color:#000;background:#fff;-webkit-text-size-adjust:100%;-ms-text-size-adjust:100%}
 4 body{margin:0;padding:0;font:12px/1.5 tahoma,arial,"Hiragino Sans GB","Microsoft Yahei","5b8b4f53";min-width:1000px;}
 5 *{margin:0;padding:0}
 6 ul{list-style:none}
 7 h1,h2,h3,h4,h5,h6{font-size:100%;font-weight:500}
 8 a,a:link,a:hover,a:active{color:#000;}
 9 a:hover{text-decoration:none;border-bottom:1px solid #000;}
10 ins,a{text-decoration:none}
11 .clearfix:after{visibility:hidden;display:block;font-size:0;content:" ";clear:both;height:0}
12 .clearfix{zoom:1}
13 
14 /* 结束reset样式 */

操作cookie的方法：

 1 <script>
 2               (function () {
 3                    var Cookie = {
 4                   get: function (name) {
 5                     var name = name + "=";
 6                     var ca = document.cookie.split(';');
 7                     for(var i=0; i<ca.length; i++) {
 8                         var c = ca[i];
 9                         while (c.charAt(0)==' ') c = c.substring(1);
10                         if (c.indexOf(name) != -1) return c.substring(name.length, c.length);
11                     }
12                     return "";
13                   },
14                   remove: function (name,path,domain) {
15                       if (this.get(name)) {
16                           document.cookie = name + "=" 
17                           + ((path) ? "; path=" + path : "") 
18                           + ((domain) ? "; domain=" + domain : "") 
19                           + "; expires=Thu, 01-Jan-70 00:00:01 GMT";
20                       }
21                   }
22                 };
23                 
24                 document.getElementById("linkReturnOldVersion").onclick = function () {
25                   Cookie.remove('NEW_ALIPAY_HOME', '/', 'alipay.com');
26                   location.href = '//my.alipay.com/portal/i.htm';
27                 };
28               })();
29              
30             </script>

恩，就这样！
