Javascript日历未显示前几年

Question

我有来自slimpicker.js的代码，我用它来获取日历。

我的问题是我需要前几年，比如2012年，2012年，2010年等等。 有人可以告诉我该怎么做吗？

// String building is such fun.

draw: function() {
    var str = '<table>';

    // Making dropdowns
    if (this.options.showMonth || this.options.showYear) {
        str += this.addMonthYearDropdowns();
    }
    str += '<tbody>';

    var calendarDate = new Date();
    calendarDate.setFullYear(this.calendarYear, this.calendarMonth, 1);
    // Leap year
    this.options.daysInMonth[1] = (calendarDate.isLeapYear() ? 29 : 28);

    // The first day is set as current
    var currentDay = (1-(7+calendarDate.getDay()-this.options.startDay)%7);

    str += '<tr>';
    this.options.dayNames.each( function(name, index) {
        str += '<th>' + this.options.dayNames[(this.options.startDay+index)%7].substr(0, this.options.dayChars) + '</th>';
    }, this);
    str += '</tr>';

    // Keeping track of row for hoveredDay purposes
    var row = 0;
    while (currentDay <= this.options.daysInMonth[this.calendarMonth]){
        row += 1;
        str += '<tr>';
        for (i = 0; i < 7; i++){
            if ((currentDay <= this.options.daysInMonth[this.calendarMonth]) && (currentDay > 0)){
                str += '<td><a href="#' + this.calendarYear + '|' + (parseInt(this.calendarMonth) + 1) + '|' + currentDay + '" class="' + this.options.dayClass;
                // Show the currently selected day
                if ( (currentDay == this.currentDay) && (this.calendarMonth == this.currentMonth) && (this.calendarYear == this.currentYear) ) {
                    str += ' ' + this.options.selectedClass;
                    this.hoverRow = row;
                    this.hoverCol = i;
                }
                // Show today
                if ( (currentDay == this.nowDay) && (this.calendarMonth == this.nowMonth) && (this.calendarYear == this.nowYear) ) {
                    str += ' ' + this.options.todayClass;
                }
                str += '">' + currentDay + '</a></td>';
            } else {
                str += '<td class="' + this.options.emptyClass + '"> </td>';
            }
            currentDay++;
        }
        str += '</tr>';
    }

    str += '</tbody></table>';

    this.calendar.set('html', str);
    this.calendarRows = row;
    this.position();
    this.addCalendarEvents();
},

addMonthYearDropdowns: function () {
    var str = '<thead><tr><th colspan="7">';
    if (this.options.showMonth) {
        str += '<select tabindex="'+this.tabIndex+'" class="' + this.options.monthClass + '">';
        this.options.monthNames.each( function(name, index) {
            str += this.addOption(index,name,parseInt(this.calendarMonth));
        }, this);
        str += '</select>';
    }
    if (this.options.showYear) {
        str += '<select tabindex="'+this.tabIndex+'" class="' + this.options.yearClass + '">';
        if (this.options.yearOrder == 'desc'){
            for (var y = this.options.yearStart; y > (this.options.yearStart - this.options.yearRange - 1); y--){
                str += this.addOption(y,y,parseInt(this.calendarYear));
            }
        } else {
            for (var y = this.options.yearStart; y < (this.options.yearStart + this.options.yearRange + 1); y++){
                str += this.addOption(y,y,parseInt(this.calendarYear));
            }
        }
        str += '</select>';
    }
    str += '</th></tr></thead>';
    return str;
},

应该在某处...
