This event is emitted when a link is followed through Unpoly.
The event is emitted on the <a> element that is being followed.
Changing render options
Listeners may inspect and manipulate render options for the coming fragment update.
The code below will open all form-contained links in an overlay, as to not
lose the user's form data:
up.on('up:link:follow', function(event, link) {
if (link.closest('form')) {
event.renderOptions.layer = 'new'
}
})
