Own encapsulation of a simple countdown function example _javascript tips

Because the usual work is very commonly used to this function, so use this national day holiday, to comb and the original code to improve, and then integrated a common function, and finally encapsulated this "simple Countdown" function.

The countdown method has the following features:

1. Match the current computer time according to the specified date

2. Set the countdown for different time periods within each day by specifying an array parameter.

* The method has not been detected by the actual work, the stability is unknown (if the actual work through, will delete this paragraph)

function Countdown (date,target,filter) {var settime = new Date (date). GetTime (), timer = null;

    function core () {var nowtime = new Date (). GetTime (), Lefttime = 0, d = 0,h = 0,m = 0,s = 0;
      Conditation @ doublue time if (filter.length) {settime = new Date ();
        for (Var i=0,l=filter.length;i<l;i++) {settime.sethours (filter[i]);
        Settime.setminutes (0);
        Settime.setseconds (0);
        if (Nowtime < Settime.gettime ()) {break;
          }else if (i = = filter.length-1) {settime.setdate (Settime.getdate () +1);
        Settime.sethours (Filter[0]);
    }}////////////////////////////Lefttime = Math.ceil ((settime-nowtime)/1000);
      if (nowtime <= settime) {d = ~ ~ (lefttime/86400);
      H = ~ ~ (lefttime%86400/3600);
      m = ~ ~ (LEFTTIME%86400%3600/60);
      s = ~ ~ (lefttime%86400%3600%60);
    Timer = settimeout (CORE,1E3); }else{cleartimeout (timer);
    timer = null;
    
  //here set out format target.innerhtml = ' d: ' +d+ ' H: ' +h+ ' m: ' +m+ ' s: ' +s;
Core (); }
