Bind an event handler to the "focusout" event, or trigger that event on an element.

.on( "focusout" [, eventData ], handler )Returns: jQuery

Description: Bind an event handler to the "focusout" event.

  • version added: 1.7.on( "focusout" [, eventData ], handler )

    • "focusout"

      The string "focusout".

    • eventData

      An object containing data that will be passed to the event handler.

    • handler

      A function to execute each time the event is triggered.

This page describes the focusout event. For the deprecated .focusout() method, see .focusout().

The focusout event is sent to an element when it, or any element inside of it, loses focus. This is distinct from the blur event in that it supports detecting the loss of focus on descendant elements (in other words, it supports event bubbling).

This event will likely be used together with the focusin event.

Example:

Watch for a loss of focus to occur inside paragraphs and note the difference between the focusout count and the blur count. (The blur count does not change because those events do not bubble.)
