    var nowTime = nowLocalTime.toLocaleTimeString()
    var s = nowLocalTime.getSeconds()
    var h = nowLocalTime.getHours()
    var m = nowLocalTime.getMinutes()
     var sh = 17 - h
     if(sh >= 0){
        sh = sh+"小时"
     }else{
        sh = ""
     }
     var sm = 60 - m;
     if(sm == "0"){

     }else{
        sm = sm +"分钟"

     var ss = 60 - s 
     if(ss == "0"){
        ss = ""
     } else {
        ss = ss + "秒"
     }
    // s == "0" // 一分钟一次
