This feature is experimental. It may be changed or removed in a future version.
Your target selectors may use this pseudo-selector to reference the element that triggered the change.
The origin element is automatically set to a link that is being followed
or form that is being submitted. When updating fragments
programmatically through up.render()
you may pass an origin element as an { origin }
option.
Even without using an :origin
reference, the
origin is considered
when matching fragments in the current page.
Instead of :origin
you may also use the ampersand character (&
).
You may be familiar with the ampersand from the Sass CSS preprocessor.
