搞了一个星期，终于搞掂了，把代码贴出来给大家分享一下哈！

<script language="JavaScript">
<!--
function createXMLObject()
{
    try
    {
        if(window.XMLHttpRequest)
        {
            xmlhttp = new XMLHttpRequest();
        }
        // code for IE5、IE6
        else if(window.ActiveXObject)
        {
            xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
        }
    }
    catch(e)
    {
        xmlhttp=false;
    }
    return xmlhttp;
}

function clear_auth()
{
    try
    {
      if(navigator.userAgent.indexOf("MSIE")>0)         //IE浏览器实现注销功能
      {
        document.execCommand("ClearAuthenticationCache");
      }
      else if(isFirefox=navigator.userAgent.indexOf("Firefox")>0)       //Firefox实现注销功能
      {
        var xmlhttp = createXMLObject();
        xmlhttp.open("GET",".force_logout_offer_login_mozilla",true,"logout","logout");
        xmlhttp.send("");
        xmlhttp.abort();
      }
      else       //Google等浏览器实现注销功能
      {
         var xmlHttp = false;
         if(window.XMLHttpRequest)
         {
            xmlHttp = new XMLHttpRequest();
         }
         xmlHttp.open("GET", "./", false, "logout", "logout");  
         xmlHttp.send(null);
         xmlHttp.abort();
      }
    }
    catch(e)
    {
        alert("there was an error");
        return false;
    }
    parent.window.location = parent.window.location;
}
//-->
</script>
