javascript - What is the difference between “this”, “$this” and “$(this)”? -

-

what difference between these 3 forms:

this $this $(this)

in typical usage you'll see them (the $this usage may vary):

  • this - refers dom element in handler you're on, may object entirely in other situations, it's context.
  • $this - created var $this = $(this) cached version of jquery wrapped version efficiency (or chain off $(this) same in many cases).
  • $(this) - jquery wrapped version of element, have access all methods (the ones in $.fn specifically).
