This release makes it easier to migrate to a recent version of Unpoly when your app still depends on jQuery.
Unpoly dropped its jQuery dependency with version 0.60.0, but retains optional jQuery support through functions like
up.$compiler() and up.$on(). All Unpoly functions that take a native element as an
argument may also be called with a jQuery collection as an argument.
The following changes to the optional jQuery support were implemented:
In an ES6 build pipeline, Unpoly's jQuery support no longer requires window.jQuery to be defined before
Unpoly is imported into the build. You still need to define window.jQuery, but you may do so at any time in your
scripts, regardless of load order.
jQuery support functions like up.$compiler() now fail with a helpful message if the developer
forgets to define window.jQuery.
This release also exposes some convenience functions and selectors:
New experimental function up.event.halt(). It prevents the event from bubbling up the DOM.
It also prevents other event handlers bound on the same element. It also prevents the event's default action.
New experimental function up.form.fields(). It returns a list of form fields within the given element.
The selector form[up-validate] is now supported. It performs
server-side validation when any fieldset within this form changes. Previously only the variant
input[up-validate] was supported.
Upgrading
If you're upgrading from an older Unpoly version you should load unpoly-migrate.js
to polyfill deprecated APIs.
Changes handled by unpoly-migrate.js are not considered breaking changes.
