docment.write 写 script

<script type="text/javascript">var cnzz_protocol = (("https:" == document.location.protocol) ? " https://" : " http://");document.write(unescape("%3Cspan id='cnzz_stat_icon_1255442790'%3E%3C/span%3E%3Cscript src='" + cnzz_protocol + "s11.cnzz.com/stat.php%3Fid%3D1255442790%26show%3Dpic' type='text/javascript'%3E%3C/script%3E"));</script>

可以不用 unescape  如有 "/" 字符 要进行  "\/" 转义
