public class TimeSelector

extends java.lang.Object

TimeSelector is a utility class to handle the creation of a set of time drop-down menus. The code is broken into a set of static methods for quick and easy access to the individual select objects:

  ElementContainer ec timeSelect = new ElementContainer();
  String myName = "mytime";
  ec.addElement(TimeSelector.getHourSelector(myName));
  ec.addElement(TimeSelector.getMinuteSelector(myName));
  ec.addElement(TimeSelector.getAMPMSelector(myName));
  

There are also methods which will use attributes to build a complete time selector in the default 12hr format (eg HH:MM am/pm):

  TimeSelector ts = new TimeSelector(myName);
  timeSelect = ts.ecsOutput();
  

Minutes/Seconds are by default rounded to the nearest 5 units although this can be easily changed. 24hr TimeSelectors can also be produced. The following example creates a full precision TimeSelector (eg HH:MM:SS):

  TimeSelector ts = new TimeSelector(myName);
  ts.setTimeFormat(TimeSelector.TWENTY_FOUR_HOUR);
  ts.setMinuteInterval(1);
  ts.setSecondInterval(1);
  ts.setShowSeconds(true);
  timeSelect = ts.toString();

output

public java.lang.String output()

Used to build the popupmenu in HTML. The properties set in the object are used to generate the correct HTML. The selName attribute is used to seed the names of the select lists. The names will be generated as follows:

• selName + "_hour"
• selName + "_minute"
• selName + "_ampm"

If onChange was set it is also used in the generation of the output. The output HTML will list the select lists in the following order: hour minute ampm. If setShowSeconds(true) is used then an addition second select box is produced after the minute select box. If setTimeFormat(TimeSelector.TWENTY_FOUR_HOUR) is used then the ampm select box is omitted.

Returns:

A String with the correct HTML for the date selector.

toString

public java.lang.String toString()
