使用以下代码：

<img src="http://v.t.qq.com/share/images/s/weiboicon16.png" align="absmiddle"/> <a href="javascript:void(0)" onclick="postToWb('yuyuzi');" style="height:16px;font-size:12px;">转播到腾讯微博</a><script type="text/javascript">
 function postToWb(myid){
  var neiRong=document.title.replace(/重症肌无力病友之家/,'#重症肌无力病友之家#')+':'+document.getElementById(myid).innerText
  var _t = encodeURIComponent(neiRong);
  
  var _url = encodeURIComponent(document.location);
  var _appkey = encodeURI("e4e942d2773d48ecafb85e81945fdb1e");//你从腾讯获得的appkey
  var _pic = encodeURI('http://www.9b01.net/zzjwl/images/logo.gif');//（例如：var _pic='图片url1|图片url2|图片url3....）
  var _site = 'http://www.9b01.net';//你的网站地址
  var _u = 'http://v.t.qq.com/share/share.php?url='+_url+'&appkey='+_appkey+'&site='+_site+'&pic='+_pic+'&title='+_t;
  window.open( _u,'', 'width=700, height=680, top=0, left=0, toolbar=no, menubar=no, scrollbars=no, location=yes, resizable=no, status=no' );
 }
</script>

这是主楼调用，回帖中调用方法是：

<img src="http://v.t.qq.com/share/images/s/weiboicon16.png" align="absmiddle"/> <a href="javascript:void(0)" onclick="postToWb('yu<%=rs("id")%>');" style="height:16px;font-size:12px;">转播到腾讯微博</a>
