Use JavaBean to create your online calendar (2)

JavaBean Program Analysis

I want to introduce some of the main methods in HtmlCalendarNotePad. I believe they will be helpful to you.

Public void setYear (int year) // sets the year. The default value is the current year.
Public int getYear () // obtain the year. The default value is the current year.
// This is written in a standard Java program. Because a Java program is a class, this setXXX/getXXX is often written.
Public void setMonth (int month) // sets the month (1-12). The default value is the current month.
Public int getMonth () // obtain the month (1-12). The default value is the current month.
Public void setStyle (int style)
Public int getStyle ()
// Set/get the style of the calendar)
// It is the first day of a week on Sunday (HtmlCalendarNotePad. SUNDAY_FIRST) or the first day of a week on Monday (HtmlCalendarNotePad. MONDAY_FIRST)

// The default value is HtmlCalendarNotePad. SUNDAY_FIRST.
Public void setLocale (Locale loc) // sets the region code (Locale). The default value is Locale. PRC.
Public Locale getLocale () // obtain the region code (Locale). The default value is Locale. PRC.

Public void setAction (int day, String actionUrl, String target_frame)
// Set a hyperlink to process the request. If any error occurs, this method returns an empty string.
// You can set a common URL, such as "http://www.yesky.com/action.jsp"
// Or a javascript function name, such as "myFunction"
// The date will be passed to the URL as a parameter or a string value to javascript. The format is yyyymmdd.
// Target_frame can be a null string.
For example:
If setAction (21, "http://www.yesky.com/", "_ blank") is called ")
Hyperlink: <a href = "http://www.yesky.com /? Date = 20000621 "target = _ blank> 21 </a> 〉

Public void setActions (String actionUrl, String target_frame)
// You can also set a hyperlink for each day of a month

Now let me share with you the attractive Bean: (HtmlCalendarNotePad. java ).
