让 IE6/7/8 也支持HTML5标签的方式

方式一：引入Google的HTML5.js线上文件

1 <!–[if lt IE9]> 
2 <script src="http://html5shiv.googlecode.com/svn/trunk/html5.js"></script>
3 <![endif]–>

方式二：自定义

 1 <script> 
 2    (function() {
 3      if (! 
 4      /*@cc_on!@*/
 5      0) return;
 6      var e = "abbr, article, aside, audio, canvas, datalist, details, dialog, eventsource, figure, footer, header, hgroup, mark, menu, meter, nav, output, progress, section, time, video".split(', ');
 7      var i= e.length;
 8      while (i--){
 9          document.createElement(e[i])
10      } 
11 })() 
12 </script>

自定义方式同时ＣＳＳ需定义如下：

1 article,aside,dialog,footer,header,section,footer,nav,figure,menu{display:block}
