The ':gt(number) Selector' is used to all the elements that are greater than the specified number.
Let us simplify with the below example.
<html> <head> <title> My First Programme </title> </head> <body> <h1> JQuery </h1> <p class = "para1"> First Paragraph </p> <p class = "para2"> Second Paragraph </p> <p class = "para3"> Third Paragraph </p> <button> Click me </button> <script src = "https://cdnjs.cloudflare.com/ajax/libs/JQUERY/3.3.1/jquery.min.js"> </script> <script> $('button').click( function() { $('p:gt(1)').text("The contents of third p element got replaced") }); </script> </body> </html>
So, if you see the above code. We can see that there are three <p> elements,
<p class = "para1"> First Paragraph </p> <p class = "para2"> Second Paragraph </p> <p class = "para3"> Third Paragraph </p>
Now, just remember the count of elements starts from '0'. So, we we mark the above <p> elements with '0', '1' and '2'.
Now, since we want to change the contents of the <p> elements that are greater than 1. And if you see the above index representation, there is only one <p> element that is greater than '1'.
And with the '$('p:gt(1)')' selector.
$('button').click( function() { $('p:gt(1)').text("The contents of third p element got replaced") });
The contents of,
Gets changed.
