  $(this)...
  // do stuff with clicked element
})

and

#2

})

推荐答案

好像它们是在大多数情况下相同，但根据

Seems like they are equivalent in most cases, though "this" seems easier to type

rel =noreferrer> http://api.jquery.com/event.currentTarget/

according to http://api.jquery.com/event.currentTarget/

event.currentTarget

此属性通常等于此的函数。

This property will typically be equal to the this of the function.

如果您使用的是 jQuery。代理或其他形式的范围操纵，
此将等于w你提供的hatever上下文，而不是
event.currentTarget

If you are using jQuery.proxy or another form of scope manipulation, this will be equal to whatever context you have provided, not event.currentTarget
