formcore

A set of forms.

• Demo

Maxlength

The Maxlength component currently watches inputs and replaces returns with \r\n to normalize behavior across browsers which count returns differently.

Numeric Input

A number of features around normalizing the behavior of <input type="number"> form fields. To start, add the data-numeric-input attribute to your <input type="number"> element:

<input type="number" data-numeric-input>

Next, include the js/numeric-input.js and js/numeric-input-init.js files.

Features

1. Suppresses non-numeric input into the form field, similar to how Chrome desktop behaves with <input type="number">. This will also prevent scientific or E notation from being entered into the form field (since E and e are alphabetic).
2. Works to enforce the maxlength attribute (also works with the number of digits on max)
3. Works around bugs with <input type="number"> in Safari 6 and Firefox desktop (large numbers may be rounded or leading zeros may be truncated). In these browsers, the type is toggled to text.
4. data-numeric-input-nav-disabled attribute option: Prevent the up and down arrow keys from incrementing and decrementing the number value.

Manual Initialization

• Alternatively, if you don’t want to use our auto-initialization code (the numeric-input-init.js file, which relies on a global enhance event), you can manually initialize with new NumericInput( element ); You’re on the hook to prevent duplicate initialization when doing this manually.
