Timer countdown di 1 giorno

[vincentf]

ok, prova a cerca un countdown che si addica al progetto. ovvero che ci siano sia la data che l'ora di scadenza, poi riportalo che ti diamo una mano a settarlo.

Ho trovato questo script e funziona, però non so dove mettere mani per poter cambiare i valori

<script type="text/javascript">var CDown = function() {
    this.state=0;// if initialized
    this.counts=[];// array holding countdown date objects and id to print to {d:new Date(2013,11,18,18,54,36), id:"countbox1"}
    this.interval=null;// setInterval object
}


CDown.prototype = {
    init: function(){
        this.state=1;
        var self=this;
        this.interval=window.setInterval(function(){self.tick();}, 1000);
    },
    add: function(date,id){
        this.counts.push({d:date,id:id});
        this.tick();
        if(this.state==0) this.init();
    },
    expire: function(idxs){
        for(var x in idxs) {
            this.display(this.counts[idxs[x]], "Now!");
            this.counts.splice(idxs[x], 1);
        }
    },
    format: function(r){
        var pre='',post='',divide=', ',
            out="";
        if(r.d != 0){out += pre+r.d +" "+((r.d==1)?"day":"days")+post+divide;}
        if(r.h != 0){out += pre+r.h +" "+((r.h==1)?"hour":"hours")+post+divide;}
        out += pre+r.m +" "+((r.m==1)?"min":"mins")+post+divide;
        out += pre+r.s +" "+((r.s==1)?"sec":"secs")+post+divide;


        return out.substr(0,out.length-divide.length);
    },
    math: function(work){
        var    y=w=d=h=m=s=ms=0;


        ms=(""+((work%1000)+1000)).substr(1,3);
        work=Math.floor(work/1000);//kill the "milliseconds" so just secs


        y=Math.floor(work/31536000);//years (no leapyear support)
        w=Math.floor(work/604800);//weeks
        d=Math.floor(work/86400);//days
        work=work%86400;


        h=Math.floor(work/3600);//hours
        work=work%3600;


        m=Math.floor(work/60);//minutes
        work=work%60;


        s=Math.floor(work);//seconds


        return {y:y,w:w,d:d,h:h,m:m,s:s,ms:ms};
    },
    tick: function(){
        var now=(new Date()).getTime(),
            expired=[],cnt=0,amount=0;


        if(this.counts)
        for(var idx=0,n=this.counts.length; idx<n; ++idx){
            cnt=this.counts[idx];
            amount=cnt.d.getTime()-now;//calc milliseconds between dates


            // if time is already past
            if(amount<0){
                expired.push(idx);
            }
            // date is still good
            else{
                this.display(cnt, this.format(this.math(amount)));
            }
        }


        // deal with any expired
        if(expired.length>0) this.expire(expired);


        // if no active counts, stop updating
        if(this.counts.length==0) window.clearTimeout(this.interval);
        
    },
    display: function(cnt,msg){
        document.getElementById(cnt.id).innerHTML=msg;
    }
};


window.onload=function(){
    var cdown = new CDown();


    cdown.add(new Date(2017,1,16,19,43,46), "countbox1");
};
