HTML组件(HTMLCOMPONENTS)之四编写日历(3)(转)[@more@]

===编写日历一===

setCal()函数是主模块，我们在脚本的第一行调用它。该函数为当天（now）、和每月的第一天（firstDayInstance）建立一个Date对象。用这些对象，setCal()函数解析出关于一个月的第一天、当日，和最后一天的所有信息。

function setCal() {

// standard time attributes

var now = new Date();

var year = now.getFullYear();

var month = now.getMonth();

var monthName = getMonthName(month);

var date = now.getDate();

now = null;

// create instance of first day of month, and extract the day on which it occurs

var firstDayInstance = new Date(year, month, 1);

var firstDay = firstDayInstance.getDay();

firstDayInstance = null;

// number of days in current month

var days = getDays(month, year);

// call function to draw calendar

drawCal(firstDay + 1, days, date, monthName, year);

}
