Introduction

Date Picker extends the capability of a normal text field with a date picker library.

Get Started

The easiest way to see how the Date Picker works is to use the existing built-in App Expenses Claims. Here are the steps:

  1. Start the Joget Server  and open the App Center.

  2. Log in as admin and click on the pencil icon on the Expenses Claim  to open the App Composer. (see Figure 1)


    Figure 1

  3. Click on Expense Claim Entry and you will be directed to the Form Builder. 

  4. Click on the Date Picker  element on the canvas to open up the Date Picker properties. (see Figure 2)

  5. Click on Preview and click on the Date Picker to see it in action.

UI

NameDescription
PlaceholderThe placeholder attribute specifies a short hint that describes the expected value of an input field (e.g. a sample value or a short description of the expected format). The short hint is displayed in the input field before the user enters a value.
Display Format

The Display Format uses the jQuery date syntax. For example, the yy-M-dd displays as 2019-10-23.
Reference: https://github.com/phstc/jquery-dateFormat

When this field is left empty, the following will be considered.

  1. If current locale starts with "zh", the format will be set as "yy-mm-dd".
  2. If "Using Locate Date Format" is set in General Settings, date format based on current user's locale will be used.
  3. Otherwise, it will use "M/dd/yy".


Date Picker Year Range

Range of years to be shown

In essence, the value left of the colon ":" must be a negative number and on the right must be a positive number. It indicates to Joget Workflow how many years earlier and how many years forward to display in the year select box based on the selected year.

A value of "c-0:c+0" is also valid, this indicates to the user that he cannot change the year value (it will default to the current system year).

Sample - Show 10 years before and after
c-10:c+10
Sample - Show specific year range
2000:2020
ReadonlyDetermines if the element is editable.
Display field as Label when readonly?

Displays the value of the element as plain text when element is set to "Readonly".

Workflow

NameDescription
Workflow Variable

If the form is part of a workflow process, upon saving of the form (by clicking on "Save as Draft" or "Complete" button). The value in this input field will be saved into the corresponding workflow variable named here.

Using a non-existent Workflow Variable name

You will get the following warning with the name printed out (e.g. status) in the server log if you attempt to map to a non-existent Workflow Variable.

context attribute status does not exist in process context - adding new attributes to the process context is not allowed


Date Formatting Based On Locale

Here are the steps to set the Date Picker to automatically display the date format based on user locale ( for example ""MM/dd/yyyy" for "en_US" locale ):

  1. In System Settings:
    1. Tick the checkbox `Using Locale Date Format`.
    2. Leave the `System Date Format` field blank or empty.
    3. Tick the checkbox `Enable User Locale Selection`.
    4. Enter into the 'User Locale Options' field the locales allowed, for example "de,en_US".
    5. Save the System Settings.
  2. In your "Form Builder > Date Picker", leave the 'Display Format' property blank or empty.
  3. User logs in, sets his locale in 'My Profile'. Date Picker field will show the date format as per his/her locale.

Display Date Time Based On Coordinated Universal Time (UTC)

You can 'force' Joget to generate the date time from the data hash variable based on UTC, by adding the parameter "-Duser.timezone=UTC" in the JAVA_OPTS  variable in the Joget startup script/batch file:

set JAVA_OPTS=-Xmx2048M -Dwflow.home=./wflow/ -javaagent:./wflow/aspectjweaver-1.8.5.jar -Duser.timezone=UTC -javaagent:./wflow/glowroot/glowroot.jar
