Introduction to Debugging AJAX Application with Firebug

[kindofanonymous]

Thanks for your clear and simple tutorial. I really appreciated you showing how to change the about:config caching settings.

why my firebug is a bug icon, not the green sign?

[bot06]

@xushenxin Looks like the older firebug had the green botton in status bar. The latest version has the bug icon not the green button.

To enable javascript debugging, notice three check box on the top menu of firebug. Click on the right most check box to debug javascript. This has changed since the earlier version.

Great Job. Nice to see experienced Ajax development in use with the Firebug Stop, Step in, Step Over; and cache/cache clear.

Thanks for this - nice and clear explaination that links all the steps together - saved me lots of time.

d00d, you talk and move around in your vid way too fast. It's almost impossible to follow along.

pay more attention

Dont promulgate that AJAX nonsense, its just a JavaScript Debugger.

I have yet to use XML in any of my "AJAX" applications. XML is great for describing data across multiple platforms, in practice parsing XML in Javascript is much slower than splitting a token delimited data string returned from any server.

Most of the magic is only Javascript.

[nessus42]

Javascript is a programming language, while Ajax is a style of programming using Javascript that involves asynchronous callbacks. Yes, the "X" in Ajax stands for XML, but these days JSON is probably used more than XML. Good luck convincing anyone to use the name "Ajaj" instead, however.

[part2themovie]

No, I was saying what he was using was a debugger. I'll never use the term AJAX or WEB 2.0, I don't try convince people of anything. My youtube rantings are as far as I'll go. These guys need to go to a few acronym annonymous meetings, all the joking aside, though its like calling direct X ACANP.. if you can figure that one out

[nessus42]

No, I can't really figure that one out. Javascript is a programming language -- you could use it from the command line, or to control an airplane. Ajax is specifically Javascript in a web browser dealing with asynchronous calls to a web server. There's a reason for the acronym, because there's an important distinction to be made and understood.

[part2themovie]

my point was that ajax is bullshit. xmlobject request is just another function in javascript, the whole acronym describes networked interactions possible with this "newly"discovered technique and most of what is called ajax does no networking, ie frameworks, drag and drog, etc  bahhh..

[nessus42]

I think you're being silly. If I told people that I'm doing Javascript programming, I could, for instance, be writing a command-line utility in Javascript. Typical? No, but not completely outlandish. On the other hand, if I say I'm doing Ajax programming, I might be doing it in Java using GWT. If I tell them that I'm doing Ajax programming using Javascript and jQuery, then they have even a better feel for what I'm doing. Words that help people understand what you're doing are a good thing.

[part2themovie]

I think you're the one being silly. Your whole explanation just exemplifies what I was bringing across. AJAX is nothing new, there is no distinction between normal javascript programming and what they call "AJAX", as in the acronym that popped out of nowhere alongside web 2.0. If you're a web developer you know the mean absolutely nothing except buzzwords to make clients feel like you're doing something extravagant. AJAX is nonsense, people who try to promulgate web 2.0 culture are evil :|

Translation: Idiot on the Internet tries to act cool and elite by rebelling against buzzwords via comments on a YouTube video.

[part2themovie]

wow..

[shogo2040]

thank you! I haven't used it in that way!! This is very helpful!

[Brainmold]

Can this fix the reply button problem?

[zmt264]

what did he do with: about:config ???

[chailey]

That really helped - I squashed a bug in my simple AJAX with the help of this video - many thanks!

[clayppl69]

nice job
