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