A ajax tutorial for beginners
2007-12-05 19:26:00
What is ajax ?AJAX is an acronym for Asynchronous JavaScript And XML. AJAX is not a programming language. but simply a development technique for creating interactive web applications.A traditional web application will submit input (using an HTML form) to a web server. After the web server has processed the data, it will return a completely new web page to the user.Because the server returns a new web page each time the user submits input, traditional web applications often run slowly and tend to be less user friendly.With AJAX, web applications can send and retrieve data, without reloading the whole web page. This is done by sending HTTP Request to the server, and by modifying only parts of the web page using JavaScript.AJAX is based on the following open standards:JavaScript XML HTML CSS Ajax Example : Create a file called test.php and put the following codes.<html><head><script src="hint.js"></script></head ><body><form>First Name:<input...

The goal of the language is to allow web developers to write dynamically generated pages quickly." This is generally a good definition of PHP. However, it does contain a lot of terms you may not be used to. Another way to think of PHP is a powerful, behind the scenes scripting language that your visitors won't see! When someone visits your PHP webpage, your web server processes the PHP code. It then sees which parts it needs to show to visitors(content and pictures) and hides the other stuff(file operations, math calculations, etc.) then translates your PHP into HTML. After the translation into HTML, it sends the webpage to your visitor's web browser. Creating first php enabled page Create a file named hello.php and put it in your web server's root directory (usually ...
