Class: Mechanize::Form::MultiSelectList
- Defined in:
- lib/mechanize/form/multi_select_list.rb
Overview
This class represents a select list where multiple values can be selected. MultiSelectList#value= accepts an array, and those values are used as values for the select list. For example, to select multiple values, simply do this:
list.value = ['one', 'two']
Single values are still supported, so these two are the same:
list.value = ['one']
list.value = 'one'
