How to count child element using jQuery ?
It is very simple to count the number of child elements in the HTML file using jQuery. For example: If you have a parent element consisting of many children elements then you can use .length or.children().length method as given below.
Syntax:
var len=$("#parentID").length;
or
var count = $("#parentId").children().length;
