1. jQuery Hands-on 1 Addition
Write a function named add() that accepts 2 numbers from users, and returns the sum (integer) of the same.
Get the values of the input fields (IDs #num1 and #num2) from the user, and display the sum in the input field ID #total when the button is clicked.
For invalid inputs, the result should be displayed as 'NaN'.
