The example in this article describes how jQuery obtains the number of child elements. Share it with everyone for your reference. The specific analysis is as follows:
//获取id=div1下的子元素的个数
$('#div1').children().length;
//获取id=div1下的span元素个数
$('#div1').children('span').length;I hope this article will be helpful to everyone’s jQuery programming.
