Aborts requests targeting a fragment or layer.
Always emits the event up:fragment:aborted, regardless of whether there were requests to abort.
If a request was aborted, the event up:request:aborted will also be emitted.
There is also a low-level up.network.abort() function, which aborts requests
matching arbitrary conditions.
Aborting requests targeting a fragment
To abort pending requests targeting an element or its descendants,
pass a reference or CSS selector for that element:
up.fragment.abort(element)
up.fragment.abort('.foo')
You may also pass an { origin } or { layer } option to help look up the selector.
Aborting requests targeting a layer
To abort all requests targeting elements on a given layer,
pass a { layer } option:
up.fragment.abort({ layer: 'root' })
Aborting all requests
This would abort requests targeting any elements on any layer:
up.fragment.abort({ layer: 'any' })
