Description

Now we need to specify what should be done with the form when the user submits it by clicking the Calculate button.

Forms have an onsubmit event that can execute a function when the form is submitted.

For example, in document.getElementById('my-form').onsubmit = processForm;, the function processForm will run when the form is submitted.

Assign a function named calculate to the onsubmit event of your form.

You will create the calculate function later.
