jQuery计时器倒数数组

Question

i have this JSFiddle that has the script to do the multiple timers, but only the last one works, i'd searched a lot about this, and didn't find an answer.

I suppose that the problem is in the array of timers, but not sure, can you help?

jQuery.fn.countdown = function (yr, mes, d, h, m, s) {
    $that = $(this);
var delta = 0;

var start = function (yr, mes, d, h, m, s) {
    theyear = yr;
    themonth = mes;
    theday = d;
    thehour = h;
    theminutes = m;
    theseconds = s;

    var today = new Date();
    var todayy = today.getYear();
    if (todayy < 1000) todayy += 1900;
    var todaym = today.getMonth();
    var todayd = today.getDate();
    var todayh = today.getHours();
    var todaymin = today.getMinutes();
    var todaysec = today.getSeconds();

    var todaystring = montharray[todaym] + " " + todayd + ", " + todayy + " " + todayh + ":" + todaymin + ":" + todaysec;

    var futurestring = montharray[mes - 1] + " " + d + ", " + yr + " " + thehour + ":" + theminutes + ":" + theseconds;

    dd = Date.parse(futurestring) - Date.parse(todaystring) + delta;

    dday = Math.floor(dd / (60 * 60 * 1000 * 24) * 1);
    dhour = Math.floor((dd % (60 * 60 * 1000 * 24)) / (60 * 60 * 1000) * 1);
    dmin = Math.floor(((dd % (60 * 60 * 1000 * 24)) % (60 * 60 * 1000)) / (60 * 1000) * 1);
    dsec = Math.floor((((dd % (60 * 60 * 1000 * 24)) % (60 * 60 * 1000)) % (60 * 1000)) / 1000 * 1);

    if (dday < 0 && dhour < 0 && dmin < 0 && dsec < 1) {
        alert("ended");
        return;
    } else {
        $that.html("<span><strong>" + dday + "</strong><span> Days | " + "<span><strong>" + dhour + "</strong></span> Hours | " + "<span><strong>" + dmin + "</strong></span> Minutes");
    }

    setTimeout(function () {
        start(theyear, themonth, theday, thehour, theminutes, theseconds);
    }, 1000);
}
return {
    start: function () {
        start(yr, mes, d, h, m, s);
    },
    addTime: function (ms) {
        delta += ms;
    }
}

};

this is what makes the countdown. check the rest in jsfiddle

The problem is that you are ommiting var keyword when declaring variables, thus they are declared as global and shared between timers. This should work ( jsfiddle ):

var $that = $(this);

...

var theyear = yr;
var themonth = mes;
var theday = d;
var thehour = h;
var theminutes = m;
var theseconds = s;

...

var dd = Date.parse(futurestring) - Date.parse(todaystring) + delta;

var dday = Math.floor(dd / (60 * 60 * 1000 * 24) * 1);
var dhour = Math.floor((dd % (60 * 60 * 1000 * 24)) / (60 * 60 * 1000) * 1);
var dmin = Math.floor(((dd % (60 * 60 * 1000 * 24)) % (60 * 60 * 1000)) / (60 * 1000) * 1);
var dsec = Math.floor((((dd % (60 * 60 * 1000 * 24)) % (60 * 60 * 1000)) % (60 * 1000)) / 1000 * 1);
