________________________________________________________________
一直写html4后来想试一下html5，然后发现IE9以下的浏览器不兼容html5标签，再网站搜索了一些解决办法，但是都会出现这样或那样的问题，比如说
<!--[if lt IE9]>
<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>
<![endif]-->
在ie8以下的浏览器中就会将<!--[if lt IE9]><![endif]-->这对标签给输出出来，
在此想问一下大家有没有什么更好的解决办？
