以下两种方法有什么区别吗?比#2快#1?
is there any difference between the following two methods? is #1 faster than #2 ?
#1

$(this)...
// do stuff with clicked element
})
and
#2
$('#selector').on('click',function(e){
$(e.currentTarget)....
// do stuff with clicked element
})
答
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
