Zend: PHP Security Webinar

Posted by: Jordan in XSS, Security, Programming, PHP, JavaScript on Jul 02, 2008

I attended the Zend: PHP Security Webinar today which is a free one hour course by Zend using Webex presented by Kevin Schroeder. I'll use this blog for my notes and to discuss some of the information presented. The actual webinar presented a lot more information than this and I expect the Zend course covers even more. This brief introduction was enough to entice me to signing up for the full

JSON

Posted by: Jordan in Programming, JSON, JavaScript, Feedparser on Jun 22, 2008

JSON seems to be a popular term appearing everywhere now. I discovered it while working on CCIT and ran into a Cross Site/Domain AJAX issue. Well, I had a bit of time today to look into it and I learned quite a bit.

Crashing IE

Posted by: Jordan in Programming, JavaScript on Jun 17, 2008

IE still has a lot of bugs and I thought most were fixed in IE 7. This one bug I discovered while working with CCIT.

Cross Site/Domain AJAX

Posted by: Jordan in JavaScript, CodeCall on Jun 16, 2008

Include a JavaScript file from a JavaScript file

Posted by: Jordan in Programming, JavaScript on Jun 10, 2008

It is fairly easy to include a JavaScript file in your HTML. You can read a CodeCall Tutorial on it HERE.

But what if you wanted to include another external JavaScript file from inside your first external JavaScript file (in this case you would include another file from javaScriptFile.js)? I needed to do this in order to finish one of my projects, CCIT. I found two ways to accomplish this.
