Datebox

Employment/Purpose

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

Keyboard Navigation 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 You can customize the rendering of the calendar at the client by JavaScript code that overrides Renderer.

Example

ZKComRef Datebox Example.PNG

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

Integrate Moment.js

Since 8.5.1 The JavaScript widgets including Datebox,Timebox,Timepicker rely on moment.js and moment-timezone.js to handle time zone information more accurately.

To check the included moment.js version, enter zk.mm.version in the browser developer console tab.


Properties and Features

Constraint

You can specify the date range to accept by the constraint property with one or multiple following values:

  • no empty
  • no future
  • no past
  • no today.


It also supports an interval 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 must be yyyMMdd. It is independent of the locale.
  2. The date specified in the above constraints (before/after/between) is included. For example, "before 20071225" includes December 25, 2007 and any day before it, and "after 20110305" includes March 5, 2011 and any day after 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();

Multiple Constraints

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

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

Custom Error Message

If you prefer to display a different message from 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 a 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')}"/>

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"/>

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 to change the format dynamically, as depicted below.

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

Length Option

Since 5.0.7

In addition to specifying the format explicitly, you could specify the length option. It supports four different length options mentioned at java.text.DateFormat:

  • short
  • medium
  • long
  • full

For example, you could specify the styling rather than the real format as follows.

<datebox format="short"/>
<datebox format="long"/>

Then the real format of the datebox will be decided at run-time depending on the configuration. For more information, please refer to ZK Developer's Reference: Date and Time Formatting.

In addition, you could specify the format for both date and time by using the syntax:

format="option_for_date+option_for_time"

For example,

<datebox format="medium+full"/>

Warning

Because Java default locale provider changes since JDK 9, the built-in formats (e.g. long) for some locales might change since JDK 9. We recommend you to use a fixed format pattern.

Validation

If a user's input doesn't match the specified format, a Datebox will show an error message. It's a client-side validation.

Locale

Default: depends on the current locale (i.e., Locales.getCurrent()) at run-time

You can enforce the locale for an individual component such as:

<datebox locale="de-DE" format="full"/>
<datebox locale="fr" format="full"/>

Multiple-Eras Calendar

Since 9.6.0 Datebox can display some multiple-eras calendar systems including:

  • ROC(Taiwan): locale="zh-TW-u-ca-roc"
  • Japan: locale="ja-JP-u-ca-japanese"
  • Buddhist: locale="th-TH-u-ca-buddhist"

Position

Since 8.0.3

By default, the popup position is set to after_start, for other possible popup positions please refer to Popup#Position.

The First Day of the Week

The first day of the week is decided by the locale by default. (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 the use of the session attribute and the library property. Please refer to The First Day of the Week for details.
