给你一段js脚本，看看就会了：function IsInstallQQ()
{
try
{
var xmlhttp=new ActiveXObject("TimwpDll.TimwpCheck");
return true;
}
catch(e)
{
return false;
}
return false;
}
function LoadQQ(qq,webSiteName,webUrl)
{
    var boolFals=IsInstallQQ();
    if(boolFals==true)
    { 
        if(undefined==qq || null==qq || ""==qq) qq="372815415";
        if(undefined==webSiteName || null==webSiteName || ""==webSiteName) webSiteName="明道";
        if(undefined==webUrl || null== webUrl || ""==webUrl) webUrl="http://www.mdbq.com";
        location.href="Tencent://Message/?menu=yes&exe=&uin="+qq+"&websiteName="+webSiteName+","+webUrl+"&info=";
    }
    else
    {
        location.href='http://is.qq.com/webpresence/up_alarm.shtml';
    }
}
