HTML组件(HTMLCOMPONENTS)之四编写日历(2)

===编写日历一===

如果指定的年数可以被4整除，那么leapYear()函数将返回“true”，否则返回”false“：

function leapYear(year) {

if (year % 4 == 0) // basic rule

return true; // is leap year

/* else */ // else not needed when statement is "return"

return false; // is not leap year

}

getMonthName()函数返回指定月份的名字：

function getMonthName(month) {

// create array to hold name of each month

var ar = new Array(12);

ar[0] = "January";

ar[1] = "February";

ar[2] = "March";

ar[3] = "April";

ar[4] = "May";

ar[5] = "June";

ar[6] = "July";

ar[7] = "August";

ar[8] = "September";

ar[9] = "October";

ar[10] = "November";

ar[11] = "December";

// return name of specified month (parameter)

return ar[month];

}
