Datebox

Employment/Purpose

An edit box for holding a date. After click on the calender, a calender will pop-up for inputting date.

Mouseless Entry datebox

  • Alt+DOWN to pop up the calendar.
  • LEFT, RIGHT, UP and DOWN to change the selected day from the calendar.
  • ENTER to activate the selection by copying the selected day to the datebox control.
  • Alt+UP or ESC to give up the selection and close the calendar.


Customization

Since 5.0.3, the rendering of the calendar can be customized at the client by providing JavaScript code that overrides Renderer.

Example

 <datebox lenient="true" buttonVisible="false" />
 <datebox lenient="false" compact="false" buttonVisible="true" />


Properties

Displayed Time Zones

The image below shows the new Datebox functionality which allows the user to change the time zone to other predefined time zones. Viewing the zul markup provided below the image we can see that the displayedTimeZones is set to "GMT+12,GMT+8". These options are specified by the developer and restrict the user to the available time zones.

ZKComRef Datebox Timezone.png

<datebox id="datebox1" format="M/d/yy KK:mm:ss a" width="150px" displayedTimeZones="GMT+12,GMT+8" timeZone="GMT+8" timeZonesReadonly="false"/>

The First Day of the Week

The first day of the week is decided by the locale (actually the return value of the getFirstDayOfWeek method in the java.util.Calendar).

Since 5.0.3, you can control the first day of the week by use of the session attribute and the library property. Please refer to The First Day of the Week for details.

Format

You are able to format the field by providing specifying the attribute with a formatting string. The default value is null. When the formatting of the datebox is null, it means the date will be outputted using the format yyyy/MM/dd.

<datebox format="MM/dd/yyyy"/>

Like any other properties, you are able change the format dynamically, as depicted below.

<datebox id="db"/>
<button label="set MM-dd-yyyy" onClick='db.setFormat("MM-dd-yyyy")'/>

Constraint

You could specify what value to accept for input controls by use of the constraint property. It could be a combination of no empty, no future, no past, no today.

To specify two or more constraints, use comma to separate them as follows.

<datebox constraint="no past,no empty"/>


If you prefer to display different message to the default one, you can append the error message to the constraint with a colon.

<datebox constraint="no empty, no future: now or never"/>

Notes:

  • The error message, if specified, must be the last element and start with colon.
  • To support multiple languages, you could use the 「l」 function as depicted in the Internationalization chapter.
<datebox constraint="no empty, no future: ${c:l('err.date.nowornever')}"/>

In addition to the constraints described in the above section (such as no future and regular expressions), the datebox supports a wide range of dates. For example,

<datebox constraint="between 20071225 and 20071203"/>
<datebox constraint="before 20071225"/>
<datebox constraint="after 20071225"/>

Notices

  1. The format of the date in the constraint is yyyMMdd. It is independent of the locale.
  2. The date specified in the constraint is included. For example, "before 20071225" includes December 25, 2007 and every day before it.
  3. The constraint is actually represented with an instance of the org.zkoss.zul.SimpleDateConstraint class. You can retrieve the parsed beginning and ending date with the getBeginDate and getEndDate methods.
((SimpleDateConstraint)datebox.getConstraint()).getBeginDate();
