jQuery:如何仅在选择范围内进行选择? [英] Jquery: How to select only within a selection?

问题描述

var parent = $("#jcontent");
var button1 = parent(".button1")

在不重用#jcontent的情况下如何选择.button1知道它在父级内部?

How to select .button1 knowing it is inside the parent while not reusing #jcontent?

我需要这样做，因为我只想将父级作为参数传递并能够对其进行高速缓存.

I need to do this because I only want to pass the parent as parameter and to be able to cache it which is faster.

推荐答案

另一种选择

var parent = $("#jcontent"); 
var button1 = $(".button1", parent) ;
