jQuery :nth-child() Selector

jQuery Web Development Front End Technology

The :nth-child() selector in jQuery is used to select all elements that are the nth child, regardless of type, of their parent.

Syntax

The syntax is as follows −

:nth-child(n|even|odd|formula)

Above, the n parameter is the index of each child to match. The even parameter selects even child element, whereas odd selects odd child element.

Example

Let us now see an example to implement the jQuery :nth-child() selector −

<!DOCTYPE html>
<html>
<head>
<style>
   .one {
      color: white;
      background-color: green;
      font-size: 16px;
      border: 2px blue solid;
   }
</style>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script>
   $(document).ready(function(){
      $("p:nth-child(2)").addClass("one");
   });
</script>
</head>
