//jq
var index = $('.A').index($(this))
console.log($('.A:not(:eq('+index+'))'))

this can use JS event delegate, currenttarget refers to the current element, and then you can bind the event to write if (event.target.tagName = = currentarget.tagName) {write the statement you want to execute in parentheses}
this way is called event proxy, also known as event delegate.

jq : $('div'). Not ($(' div'). Eq (1))
