好象是>▲ <a class=MainContentB href="#" onclick="javascript:window.open('/ldgy/main/lzvod.asp?vodpath=/ldgyxz/xx/1.rm&NewsID=1097','','toolbar=no,location=no,status=no,menubar=no,width=480,height=400')">余世维讲座之一</a><span Class=TitleMore>(3-16)</span> <font color="#FF0000">9</font><br>
错了，我加了</td></tr>还是一样的，

请问href="#" 是什么意思？
谢谢！
