Taco Class The power of jQuery all wrapped up in a Codeigniter Library

[color=green][size=4][b]The Taco class for codeigniter.[/b] [/size][/color] [color=green]——————————————————————————————————————————————————-[/color] You can see a demonstration of this libaray at http://findmeonthe.net/TACONITE/ It has lots of examples. [color=green]——————————————————————————————————————————————————-[/color] [size=3][color=blue]Updated to version:- 4.05[/color][/size]

What does this class do:

• [b]Manipulate html elements from within your controller [/b]
• [b]Transmit data via AJAX[/b]
• [b]Send JQUERY commands e.g. slideUp, fade, show, hide, replaceWith, append, etc etc. to munipulate your webpages, without reloading the pages[/b]

This class simply generates an xml file that allows you to take control of your webpage.

Where the magic happens <?php if (!defined('ABSPATH')) exit('No direct script access allowed');

[b]The power behind this library is the Taconite Plugin for JQUERY which is well documented on the [url=http://malsup.com/jquery/taconite]MALSUP[/url] website.[/b]

This example shows how you can easily manipulate the structure of the DOM. The markup is as follows.

This is the structure example div.

[/code] The following code is used in the view to request example1: [code] $('#MYBUTTON').click(function() {$.get('http://findmeonthe.net/TACONITE/index.php/taco_example/example1'); }); [/code]
