#set(value, **options) ⇒ Object

Set the value of the form element to the given value.

Parameters:

  • value (String) —

    The new value

  • options (Hash{}) —

    Driver specific options for how to set the value

Options Hash (**options):

  • :clear (Symbol, Array) — default: nil —

    The method used to clear the previous value
    nil => clear via javascript
    :none => append the new value to the existing value
    :backspace => send backspace keystrokes to clear the field
    Array => an array of keys to send before the value being set, e.g. [[:command, 'a'], :backspace]

  • :rapid (Boolean) — default: nil —

    Whether setting text inputs should use a faster "rapid" mode
    nil => Text inputs with length greater than 30 characters will be set using a faster driver script mode
    true => Rapid mode will be used regardless of input length
    false => Sends keys via conventional mode. This may be required to avoid losing key-presses if you have certain Javascript interactions on form inputs
