WW522 - Intermediate Applications of JavaScript

Course Description

Build on the skills practiced in the introductory class. Discover how JavaScript can help to validate HTML forms, providing immediate feedback when the user omits required information or makes other validation errors. Learn to create web forms for password resets and data entry, validating your web pages using client-side scripts. Create pages that will conditionally change depending on user input. Learn best practices for input validation, by string manipulation and regular expressions or creating appropriate warnings to the user. Use loops and arrays to store and show information that changes with time. Understand how to open a new window for your form or to determine if your page has been resized using BOM (Browser Object Model).

In this course, you will learn to: 

• Creating conditional statements to perform JavaScript statements only when certain criteria are met. 

• Validating form input for errors prior to submission, such as omitting required fields, so that it becomes easier for users to provide correct information. 

• Using regular expressions to match patterns for use in form validation. 

• Creating loops that will repeat statements for a certain number of times or while a certain criteria is true. 

• Creating arrays to store multiple items in a single variable. 

• Understanding the JavaScript window object.
