This part of the course covered the following:

  • handling form data — how to extract data entered into text fields; how to react to user choices in multiple choice form controls like checkboxes, radio buttons, and dropdown menus

  • form validation — during input with the  input  event, after input is complete with the  blur  event, and using HTML constraints like  required

  • AJAX GET requests — how to build a request object, declare its type, and implement its  onreadystatechange  function to handle the server response

The next part of this course covers AJAX in more detail, taking a closer look at what makes AJAX "Asynchronous," and which consequences that has on how we build web apps in JavaScript.
