jquery 打开直接跳到网页最下面，最低端

<script type="text/javascript">// <![CDATA[ BAIDU_CLB_SLOT_ID = "489794"; // ]]></script><script type="text/javascript" src="http://cbjs.baidu.com/js/o.js"></script>

$("html").scrollTop(4000)

这里的4000设成比body高度要大的值

<script type="text/javascript">// <![CDATA[ BAIDU_CLB_SLOT_ID = "551284"; // ]]></script><script type="text/javascript" src="http://cbjs.baidu.com/js/o.js"></script>

<script type="text/javascript">// <![CDATA[ BAIDU_CLB_SLOT_ID = "551289"; // ]]></script><script type="text/javascript" src="http://cbjs.baidu.com/js/o.js"></script>
