<a>感谢您的支持与信任！本博客已正常经运行</a><a id="days"></a>0<a>天</a>
<script>
var s1 = '2013-07-01';//设置为你的建站时间
s1 = new Date(s1.replace(/-/g, "/"));
s2 = new Date();
var days = s2.getTime() - s1.getTime();
var number_of_days = parseInt(days / (1000 * 60 * 60 * 24));
document.getElementById('days').innerHTML = number_of_days;
