SELECTORS - :nth-last-of-type(n) Selector

The :nth-last-of-type(n) Selector is used to select the elements, who are the 'n'th child of their parent of the same type from the end.

Let us simplify with the below example.

Example :

<html>
  	<head>
    	<title> My First Programme </title>
  	</head>

  	<body>
    	<h1> JQuery </h1>
    	
    	<div class = "newClass">
    		<p class = "para1"> First Paragraph </p>
    		<p class = "para2"> Second Paragraph </p>
    		<p class = "para3"> Third Paragraph </p>
    		<span> My Span </span>
    	</div>	
    	
    	<button> Click me </button>

      	<script src = "https://ajax.googleapis.com/ajax/libs/jquery/3.7.1/jquery.min.js"> </script>
	  
      	<script>
      
			$('button').click( function() { 
            	$('p:nth-last-of-type(1)').text("The last child of div element of p type got replaced")
            });
            
      	</script>      
  	</body>
</html>

Output :

So, if you see the above code. We can see that there are three <p> elements and a <span> element, those are inside a <div> element.

<div class = "newClass">
	<p class = "para1"> First Paragraph </p>
	<p class = "para2"> Second Paragraph </p>
	<p class = "para3"> Third Paragraph </p>
	<span> My Span </span>
</div>

Now, if you consider the DOM,

The <div> element has three children of type <p>.

<p class = "para1"> First Paragraph </p>
<p class = "para2"> Second Paragraph </p>
<p class = "para3"> Third Paragraph </p>

And one child of <span> type,

<span> My Span </span>

And on button click, the contents of third <p> element gets replaced with The third child of div element of p type got replaced.

And this happened with the :nth-last-of-type(1) element selector.

$('button').click( function() {
	$('p:nth-last-of-type(1)').text("The last child of div element of p type got replaced")
});

The moment the button is clicked, JQuery statement gets triggered.

$('p:nth-last-of-type(1)').text("The last child of div element of p type got replaced")

And the JQuery code locates the second child of <div> element of <p> type and changes its contents.
