The example in this article describes how jQuery counts the number of specified sub-elements. Share it with everyone for your reference. The specific analysis is as follows:

jQuery can access subtags through >, and then get the number of subtags through size

<div id="foo">
 <div id="bar"></div>
 <div id="baz">
  <div id="biz">
 </div>
 <span><span>
</div>
//jQuery code to count child elements
$("#foo > div").size()
Copy after login

I hope this article will be helpful to everyone’s jQuery programming.
