//隐藏
function hideMessageBar(o,t,i,j,s){
    var o = document.getElementById('NtalkerToolbar');
    i=j=1;s=o.style;
    t=setInterval(function(){
        o.offsetTop(document.body.clientHeight-34)?(s.top=(o.offsetTop-2)+"px"):clearInterval(t);
    },15);
    //显示后延迟10秒自动隐藏
    setTimeout(hideMessageBar,10000);
}
