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

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

方式二：自定义

 <script>
    (function() {
      if (!
      /*@cc_on!@*/
      0) return;
      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(', ');
      var i= e.length;
      while (i--){
          document.createElement(e[i])
      }
 })()
 </script>

自定义方式同时ＣＳＳ需定义如下：

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