dhtmlgoodies_calendar.js不适用于Firefox和Chrome

我的asp.net应用程序中有一个dhtmlgooies_calendar，并对writeCalendarContent方法进行了一些更改，以禁用过去的日期。它在Internet explorer上运行良好。但在firefox和chrome中，过去的日期仍然显示在屏幕上。

有人知道如何在那些Brower里做到这一点吗？任何帮助都将不胜感激。感谢

这是我的方法：

       function writeCalendarContent()
{
    var blockDateInPast = true;
    var calendarContentDivExists = true;
    if(!calendarContentDiv){
        calendarContentDiv = document.createElement('DIV');
        calendarDiv.appendChild(calendarContentDiv);
        calendarContentDivExists = false;
    }
    currentMonth = currentMonth/1;
    var d = new Date();
    var data = new Date();
    var AnoAtual = data.getYear();
    var MesAtual = data.getMonth();
    var DiaAtual = data.getDate();
    d.setFullYear(currentYear);
    d.setDate(1);
    d.setMonth(currentMonth);
    var dayStartOfMonth = d.getDay();
    if (! weekStartsOnSunday) {
      if(dayStartOfMonth==0)dayStartOfMonth=7;
      dayStartOfMonth--;
   }
    document.getElementById('calendar_year_txt').innerHTML = currentYear;
