QQ空间清除导航条：
<img src="/ javascript :bt_6.style.display='none";bt_7.style.display='
none';bt_8.style. Display='none';" style="display:none;"><p>gainover</p>

导航透明
<img src="/ javascript :bt_1.style.background="url()';bt_2.style.
background=' url()';bt_3.style.background='url()';bt_4.style.
background='url()';bt_5.style.background='url()';bt_6.style.background='
url()';bt_7.style.background=' url()';bt_8.style.
background='url()';"></img><font color=red>gainover</font>

导航放在顶部的代码是：
<img src=" javascript :var s=document.createElement('script');s.src=' http://wonzone.go2.icpcn.com/qzone/public/mtv_top.js ';document.body.
appendChild(s);" style=display:none></img>

如果想放低部的代码是：
<img src=" javascript :var s=document.createElement('script');s.src=' http://wonzone.go2.icpcn.com/qzone/public/mtv_bottom.js ';document.
body.appendChild(s);" style=display:none></img>
