HTML组件(HTML COMPONENTS)之四编写日历(3)
===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); }
