1. JavaScripts

2. Web design history
HTML code taken in and interpreted by the user’s machine on initial load
Static in nature
Not “static/dynamic” but singular scan static

3. Immediate Problems No “checking” functionality
Database writing
Many pages for multiple menus
Example (FGCU Alico Arena)
No User OS/Browser Detection

4. Additional HTML Limitations
No access to browser interface
No real date/time handling
Cannot create or access “Pseudo registry” files (ie: cookies)
Cannot verify field input

5. Overall Interactivity
At this point HTML pages are basically electronic Newspapers. Display only.

6. JavaScripts - Basic Definition
Created by Brendan Eich.
First implemented by Netscape Navigator 2 Beta in 1995 to make newly added support for Java applets more accessible to non-Java programmers and web designers.
Originally known as “LiveScript” called JavaScript for marketing.

7. Basic Info
JavaScript programs, or Scripts, are often directly embedded in HTML pages and executed by the browser.
Usually accessed as a listed “.js” file.

8. Basic Info
Because JavaScript is an interpreted language, it requires no preliminary compilation by the host machine. Thus it runs independent of the code.

9. Basic JavaScript Functions
Control over the browser
Background, scrollbars, navigation, status bar
User Detection
Browser, Operation System
Client-side Calculation

10. Basic JavaScript Functions
Verify User input
Text fields
Handling dates and times
Clocks, Calendars, “time of day” handling
HTML generation
JavaScript menus generated by the host machine.

11. Limitations Direct access to server or client side files
Exception (cookies)
Multithreading
May be disabled by browser

12. Common Practical Uses JavaScript menus Selection/Search Fields
Cookie generation and access
Form validation
