For an alternative approach to client-side form validation, without Java Script, check out our new article on HTML5 Form Validation which is available now in most modern browsers. The first test in the example is therefore only necessary in order to provide a different error message when the input is blank.

Normally you would modify this so that you could submit or not submit the form based on the number of items selected. Note that in this section we've been using the new ES6 syntax which may not be available in all browsers.
