Applying object in JavaScript (3)

Eight. Integrated Application
The last example demonstrates the importance of JavaScript objects. Set up a Calendar object first, and then show any one month calendar as needed. The execution process is not complicated, just specify the month and year as the object property, and then let the constructor do something else:
<script language= "JavaScript" >
/* Calendar object, Calendar.js
Usage:
obj = new Calendar (mm, yyyy);

Constructor
function Calendar (month, year)
{
Array of day names
This.days = new Array ("Sunday", "Monday", "Tuesday", "Wednesday",
"Thursday", "Friday", "Saturday");
Array of month names
This.months = new Array ("January", "February", "March", "April", "may",
"June", "July", "August", "September", "October", "November", "December");
Array of Total month
This.totaldays = new Array (31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31);
Object Properties-month and year
Correction for zero-based array index
This.month = month-1;
This.year = year;
Leap Year correction
if (this.year% 4 = 0)
{
THIS.TOTALDAYS[1] = 29;
}
Temporary variable-used later
This.rowcount = 0;
Object method
This.display = display;
Automatically run method display () Once the object is initialized
This.display ();
}
function to display calendar
function display ()
{
Create a Date object
Required to obtain basic date information
Get the "the" and "the" Month-boundary Values for calendar
obj = new Date (This.year, This.month, 1);
