Create your online calendar using JavaBean 2001-04-05 · Wayne · Yesky
Some friends have said that if there is an online diary, or a network that can remind himself to do what is going to do. Actually, such a calendar can be a one. Don't believe you look at the example below:
Wannian calendar </ title> </ head> <body bgcolor = "white"> // Settings page scripting language is Java, imported HTMLCALENDARNOTEPAD class, HTMLCALENDARNOTEPAD will tell <% @ page language = "java" import = "htmlcalendarnotepad"%> // Define a javabean, take the ID to htmlcal <jsp: usebean id = "htmlcal" scope = "session" class = "htmlcalendarnotepad" /> <% // Set the parameters, take the desired month in March, because the year is not set, the default is this year. Htmlcal.setMonth (3); // Set action, on March 24th, go to the sky, open in the new window (or open in other ways) htmlcal.setAction (24, "http: //www.yesky. COM / "," _ blank ");%> <table width = 300> <TR> <TD NOWRAP> <% = HTMLCAL.GETHTML ()%> // Output a month's calendar </ td> < / TR> </ table> </ body> </ html></p>
<p>You will see the following output results</p>
<p>Mon Tue Wed Thu Fri Sat Sun 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 24 25 25 26 27 28 29 30 31</p>
<p>This is not the same as the calendar, but it is better than the calendar, there is a pre-set link to remind you to a site, or a JavaScript function, this is not a notepad. Is there a role? Of course, you can also add some functions to make it more powerful, such as adding a form, allowing users to fill in the diary sent to your system's database, and so on. In order to complete this purpose, let's take a look at how the JavaBean program is written. JavaBean program analysis</p>
<p>I want to introduce some of the main methods in htmlcalendarnotepad, I believe everyone will help</p>
<p>Public void setYear (int year) // Set the year. The default value is the current year public int gameEear () //. The default value is current year // This is a standard Java program to write, because the Java program is a class, so often write this setXX / getXxxpublic void setMonth // set the month (1-12), the default is current Month () (1-12), the default value for the current month public void setStyle () // style // is Sunday Publici HtmlCalendarNotePad.SUNDAY_FIRST first day of the week or in the first day of the week is Monday HtmlCalendarNotePad.MONDAY_FIRST // default value HtmlCalendarNotePad.SUNDAY_FIRST public void setLocale (Locale loc) // set the region code (Locale), the default value Get regional code () // for local () //, the default value is Locale.prc</p>
<p>Public Void SetAction (int Day, String ActionURL, String Target_frame) // Sets the hyperlink to process the request. If you have any errors, this method returns an empty string. / / You can set an ordinary URL, such as "http://www.yesky.com/action.jsp"/ / or a JavaScript function name, such as" MyFunction "// will be passed as a parameter to the URL Alternatively, as a string value to javascript. Format is YYYYMMDD. // target_frame can be an empty string. Such as: If the setAction (21, "http://www.yesky.com/", "_blank") hyperlink is: <a href = "http://www.yesky.com/?date=20000621" Target = _BLANK> 21 </A></p>
<p>Public void setActions (String ActionURL, String Target_frame) // You can also set a hyperlink for a month</p>
