Constructor Details

#initialize(src: nil, csrf_token: nil, checked: false, enabled: true, size: SIZE_DEFAULT, status_label_position: STATUS_LABEL_POSITION_DEFAULT, **system_arguments) ⇒ ToggleSwitch

Returns a new instance of ToggleSwitch.

Parameters:

  • src (String) (defaults to: nil) —

    The URL to POST to when the toggle switch is toggled. If ‘nil`, the toggle switch will not make any requests.

  • csrf_token (String) (defaults to: nil) —

    A CSRF token that will be sent to the server as “authenticity_token” when the toggle switch is toggled. Unused if ‘src` is `nil`.

  • checked (Boolean) (defaults to: false) —

    Whether the toggle switch is on or off.

  • enabled (Boolean) (defaults to: true) —

    Whether or not the toggle switch responds to user input.

  • size (Symbol) (defaults to: SIZE_DEFAULT) —

    What size toggle switch to render. <%= one_of(Primer::Alpha::ToggleSwitch::STATUS_LABEL_POSITION_OPTIONS) %>

  • status_label_position (Symbol) (defaults to: STATUS_LABEL_POSITION_DEFAULT) —

    Which side of the toggle switch to render the status label. <%= one_of(Primer::Alpha::ToggleSwitch::SIZE_OPTIONS) %>

  • system_arguments (Hash) —

    <%= link_to_system_arguments_docs %>
