<script type="text/javascript">

var _gaq = _gaq || [];

_gaq.push(['_setAccount', 'UA-0000000000-1']);

_gaq.push(['_setDomainName', 'chinadoweb.com']);

_gaq.push(['_trackPageview']);

(function() {

var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.setAttribute('async', true);

ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';

var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);

})();

</script>

<div class="hide">

<script type="text/javascript">

(function() {

var baidu = document.createElement('script');

baidu.type = 'text/javascript';

baidu.setAttribute('async', true);

baidu.src = ('https:' == document.location.protocol ? 'https://' : 'http://') + 'hm.baidu.com/h.js?9af37----------';
