.focusin()

.focusin( handler(eventObject) ) Returns: jQuery

Description: Bind an event handler to the "focusin" JavaScript event.

  • version added: 1.4.focusin( handler(eventObject) )

    handler(eventObject)A function to execute each time the event is triggered.

This method is a shortcut for .bind('focusin', handler).

The focusin event is sent to an element when it, or any element inside of it, gains focus. This is distinct from the focus event in that it supports detecting the focus event on parent elements.

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

Example:

Watch for a focus to occur within the paragraphs on the page.

<!DOCTYPE html>
<html>
<head>
  <style>span {display:none;}</style>
  <script src="http://code.jquery.com/jquery-latest.js"></script>
</head>
<body>
	<p><input type="text" /> <span>focusin fire</span></p>
<p><input type="password" /> <span>focusin fire</span></p>
<script>
    $("p").focusin(function() {
         $(this).find("span").css('display','inline').fadeOut(1000);
    });
</script>
</body>
</html>
