Character counter

Availability

[SINCE Orbeon Forms 4.10]

What it does

The fr:character-counter component encapsulates an existing text control and adds a character counter next to it.

It supports the following controls:

  • xf:input

  • xf:textarea

  • xf:secret

  • fr:tinymce

Basic usage

The component is generally activated using the appearance attribute:

<fr:input bind="message-bind" appearance="character-counter">
    <xf:label>Message</xf:label>
</fr:input>

The component automatically encapsulates the specified control, here xf:input.

The component displays its counter in different ways:

  • if no max-length validation is present on the bound node

    • the counter value is the current number of characters

    • a CSS class fr-charcounter-current is present on the counter

  • if a max-length validation is present on the bound node

    • if the current length is smaller than max-length

      • the counter value is the number of remaining characters allowed

      • a CSS class fr-charcounter-remaining is present on the counter

    • if the current length is larger than max-length

      • the counter value is the number of extra characters allowed

      • a CSS class fr-charcounter-over is present on the counter

By default, fr-charcounter-over places a minus sign in front of the number of characters over the limit.

Form Builder support

The CSS bindings allow Form Builder to propose the "Character Counter" appearance to the user automatically. See How the new Form Builder Appearance Selector Works for details.
