jQuery statistics a method that specifies the number of child elements

This article demonstrates an example of how jQuery counts the number of specified child elements. Share with you for your reference. The specific analysis is as follows:

jQuery can be passed > Access the child tags, and then get the number of child tags via 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()

I hope this article has been helpful to your jQuery programming.
