CS 315 Exam Two Terms and Concepts

Previous material

Don't forget the basics of what you learned for the last test. So, remember things like HTML5, CSS, and PHP.

Basic Javascript

• Be able to write basic Javascript code.
• Understand Javascript's object model and how it is different from standard object-oriented programming models.
• Know how to use alert, confirm and prompt for simple pop-up interactions with the user.
• Know how to create and modify objects.
• Be able to do simple things with arrays.
• Know how to define and invoke functions, including simple parameter passing.
• Know how to specify patterns as regular expressions, including knowing the constructs discussed in the text. (There will definitely be questions about this stuff, similar to your fourth homework.)

Javascript and the DOM

• Understand the basics of the Document Object Model (DOM).
• Understand how getElementById is used to find elements using id attributes.
• Know the basics of the DOM 0 event model.
• Know how to write event handlers and the standard way we discussed in class of associating an event handler with an event in DOM in an unobtrusive way (the registration process).
• The form validation example from class combines a lot of these ideas at a level I expect you to be able to reproduce.
• Understand the ideas of unobtrusive Javascript and how to put them into practice.

Javascript Positioning and AJAX

• Element positioning: absolute vs. relative vs. static
• Moving elements by changing the top and left properties
• Controlling visibility
• Changing style attributes of DOM objects
• Be familiar with the basic ideas of AJAX and how they can be used to update pages without reloading. You do not need to worry about the details of AJAX Javascript syntax, but you should be familiar with the main concepts.

Servers and Security

• Know what a web server is and, in a general way, what web server software is
• Understand web security issues as discussed in class
  • Know what buffer overflow is and why it is a problem
  • Understand the basics of public key cryptography
  • Know what certificates are and how they can be used to set up a secure connection between a browser and a web server using SSL
  • Understand some simple ways to clean up input from forms and why it is important to do so

Relational Databases

• Understand what a relational database is.
• Understand why relational databases are so useful in concert with web pages.
• Understand in a general way how to use PHP to insert and select elements in MySQL databases.
• Know how to encode simple insert and select commands in SQL. Nothing too complicated. No joins required.
