Java API
Inheritance

This class is a Field component, and inherits its features and behaviors. For an overview of Field properties, events, and other important information, please refer to the Field documentation.

The DateField is a user interface component that allows users to input or select dates. It provides an intuitive and efficient way to handle date-related information in various applications. This section outlines the best practices for using the DateField component effectively.

Usages​

The DateField is best used in scenarios where capturing or displaying dates is a crucial part of the user interface or application functionality. Here are some examples of when to use the date field

  1. Event Scheduling and Calendars: Date fields are essential in applications that involve event scheduling, appointment booking, or managing calendars. They enable users to select specific dates accurately.

  2. Form Inputs: When designing forms that require date inputs, using a date field simplifies the date selection process for users. This is particularly useful for applications that collect user data or require date-based inputs.

  3. Booking and Reservation Systems: Applications that involve booking and reservation systems often require users to input specific dates. A date field simplifies the process and ensures accurate date selection.

  4. Task Management and Deadlines: Date fields are valuable in applications that involve task management or setting deadlines. Users can easily specify due dates, start dates, or other time-sensitive information.

The DateField class provides a user interface component that allows the user to enter a date, including the year, month, and day. It offers the flexibility to validate the input or use a special date picker interface.

Maximum and minimum​

You can use the setMax() and setMin() methods to specify the acceptable range of dates. If the value entered into the component is outside of the specified value, the component fails constraint validation. Also, if there is already a maximum or minimum set, the value given to the other method must be lower or higher respectively.

Display​

The DateField will, by default, display its information within the UI element based on the locale the browser is configured to. For example, users with United States configurations will see the date displayed with the month preceding the day, whereas European users will see the day before the month. This does not inhibit manipulation of the LocalDate object returned by methods from the class, however.

Static utilities​

The DateField class also provides the following static utility methods:

  • fromDate(String dateAsString): Convert a date string in yyyy-MM-dd format to a LocalDate object which can then be utilized with this class, or elsewhere.

  • toDate(LocalDate date): Convert a LocalDate object to a date string in yyyy-MM-dd format.

  • isValidDate(String dateAsString): Checks to see if the given string is a valid yyyy-MM-dd date. This will return a boolean value true if so, false otherwise.

Best practices​

To ensure an optimal user experience when using the DateField component, consider the following best practices:

  1. Consider Accessibility: Ensure that your utilization of the DateField meets accessibility standards, using proper labels, and being compatible with assistive technologies.

  2. Auto-Populate Current Date: Consider providing an option to auto-populate the current date as a default value in the date field, if appropriate for your application's use case.
