API class up.Params

The up.Params class offers a consistent API to read and manipulate request parameters independent of their type.

Request parameters are used in form submissions and URLs. Methods like up.submit() or up.replace() accept request parameters as a { params } option.

Supported parameter types

The following types of parameter representation are supported:

  1. An object like { email: 'foo@bar.com' }
  2. A query string like 'email=foo%40bar.com'
  3. An array of { name, value } objects like [{ name: 'email', value: 'foo@bar.com' }]
  4. A FormData object. On IE 11 and Edge, FormData payloads require a polyfill for FormData#entries().
