#initialize(options) ⇒ JSON

Returns a new instance of JSON.

Parameters:

Options Hash (options):

  • :url (String) —

    URL of the page which includes the link.

  • :action (String) —

    Link URL – defaults to `:url`.

  • :inputs (Hash) —

    Query parameters as `name => value` pairs. If none have been provided they will automatically be extracted from Capabilities::Submittable#action.
