jQuery selectors work very much like CSS selectors, which you may be more familiar with.
jQuery 选择器的工作方式与 CSS 选择器非常相似，您可能更熟悉它。
First, select the div, and then descend from that:
首先，选择 div，然后从它下降：
$('#my-div').find('some-selector').
or build your selector to match children of the element in question:
或构建您的选择器以匹配相关元素的子元素：
$('#my-div some-selector')

Old question, but everyone seems to have missed the scopedjQuery selector (using the scope you desired, i.e. your div selector, as the second parameter)
老问题，但每个人似乎都错过了作用域jQuery 选择器（使用您想要的作用域，即您的 div 选择器，作为第二个参数）
e.g. use
例如使用
var $matches = $('.adiv', '#mydiv');
This is a shorter equivalent of:
这是一个较短的等价物：
var $matches = $('#mydiv').find('.adiv');

var elems = jQuery(".foo", jQuery("#divYourWantToLimitTo") ); //BAD
//or
var elems = jQuery("#divYourWantToLimitTo .foo"); //Better
//or
var elems = jQuery("#divYourWantToLimitTo").find(".foo"); //BEST

jQuery provides several ways to search for specific elements:
jQuery 提供了几种搜索特定元素的方法：
$("#your_div").find(".your_things"); //Find everything inside
//-or-
$("#your_div").filter(".your_things"); //Find only the top level
//-or-
$("#your_div .your_things"); //Easiest
