#select_by(how, what) ⇒ Object

Select options by visible text, index or value.

When selecting by :text, selects options that display text matching the argument. That is, when given “Bar” this would select an option like:

<option value="foo">Bar</option>

When slecting by :value, selects all options that have a value matching the argument. That is, when given “foo” this would select an option like:

<option value="foo">Bar</option>

When selecting by :index, selects the option at the given index. This is done by examining the “index” attribute of an element, and not merely by counting.

Parameters:

  • how (:text, :index, :value) —

    How to find the option

  • what (String) —

    What value to find the option by.
