In this jQuery program, I am going to share the subtract two numbers using jQuery. This is a very easy and simple program written in jQuery to calculate any two numbers.
Create an index.html file and include the jQuery file before head tag closed.
1 2 | <script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js" type='text/javascript'></script> |
Copy paste below jQuery code inside the head tag.
1 2 3 4 5 6 7 8 9 | $(document).ready(function() { $("#calculate").click(function() { var num1 = $("#num1").val(); var num2 = $("#num2").val(); var answer = parseInt(num1) - parseInt(num2); alert(answer); $("#answer").val(answer); }); }); |
