Order of events
The UI Events specification states that focus events occur in a set order relative to one another, and goes on to describe the typical sequence of events that fire when the focus is shifted from element A to element B:
focusout
: sent before element A loses focus.focusin
: sent before element B receives focus.blur
: sent after element A loses focus.focus
: sent after element B receives focus.
However, current browser implementations fire these four events in a different order:
blur
: sent after element A loses focus.focusout
: sent after theblur
event.focus
: sent after element B receives focus.focusin
: sent after thefocus
event.
