Attributes.add()

The Attributes.add() method adds value to the attribute identified by key.

Signature

Attributes attributes.add(string key, string value)

Example

  .add('class', 'classA')
  .add('class', 'classB')

Notes

Adding multiple values to the same key will result in them being joined together (with a space) when rendering.
