On studying web programming

What are the best re开发者_如何学编程source to study the following: JavaScript, AJAX, CodeIgniter Smarty?

Though perhaps not suited as a first book on JavaScript, I recommend

JavaScript - the Good Parts by Douglas Crockford. It will keep you from doing some dumb things.

OReilly's Javascript: The Definitive Guide, 5th Edition (or later) http://www.amazon.com/JavaScript-Definitive-Guide-David-Flanagan/dp/0596101996/ref=dp_ob_title_bk

Digging into JQuery and using it is a great way to crash course into something more complex than "hello world" with javascript

In general, you will learn a lot if you just do stuff in this fashion.

1. Pick a feature you think is cool
2. Google it to find a solution
3. Instead of copy/paste, make sure you understand what the code actually does, and how
4. Change it in some way to make sure your understanding is correct \
5. Use Google to find out why your changes failed
6. Rinse/Repeat

CodeIgniter has a great User Guide. Just download CI and start building a simple web site, using the guide as a starting point and reference.

Also, I would recommend using jQuery for your JavaScript and AJAX - it will make your life much easier!

You should definitely take a visit to http://www.w3schools.com.

Net Tuts has some of the best tutorials on the net.
