2. JavaScript Programming: Web Forms
This computer science video is the second in a series of lessons that introduce JavaScript programming. In particular, this lesson introduces the web form which can be used to capture input from a user. The HTML form tag and a number of form elements (types of form control) are demonstrated including the text input, radio buttons and the select element. The form data are captured with a JavaScript function and, for now, displayed in an alert box and written onto the web page. Client side validation of form data and posting to a server are covered in a different lesson. It is assumed you already have some familiarity with HTML and have already done some programming in a high level programming language.
