3. JavaScript Programming: HTML 5 Client Side Validation
This computer science video is the third in a series of lessons that introduce JavaScript programming. This lesson demonstrates how client side validation can be performed without writing a single line of JavaScript code, thereby putting client side validation with JavaScript in context. It covers the use of HTML 5 specific validation features that can be applied as attributes to HTML form elements. These include required fields, maximum and minimum values for number fields and pattern matching using regular expressions, for example to specify the correct format of an email address. The behaviour of the submit input control is also mentioned.
This series assumes that you already have some familiarity with HTML and have already done some programming in a high level programming language.
