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:- 4.06[/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');

For this to work you need the [url=http://jquery.com]JQUERY [/url]library and the Taconite library from [url=http://malsup.com/jquery/taconite]malsup.com[/url] added to your [VIEW] file.

[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.

[color=red][size=3]In the view file[/size][/color]

<div id="example1" style="background-color: #ffa; padding:10px; border:1px solid #ccc"> 
    This is the <span style="color:#800">structure example</span> div. 
</div>

The following code is used in the view to request example1:

$('#MYBUTTON').click(function() {$.get('http://findmeonthe.net/TACONITE/index.php/taco_example/example1'); });

[color=red][size=3]In the controller the php code[/size][/color]

function example1()
        {
          $this->taco->set('after', '#example1', 'This text will go AFTER the example div.');
          $this->taco->set('before', '#example1', '<div>This div will go BEFORE the example div.</div>');
          $this->taco->set('wrap', '#example1 span', '<span style="border: 1px dashed #00F"/>');
          $this->taco->set('append', '#example1', '<div>This div is APPENDED</div>');
          $this->taco->output();    
        }

[color=red][size=3]The browser ouput is[/size][/color]

<div>This div will go BEFORE the example div.</div>
<div id="example1" style="border: 1px solid rgb(204, 204, 204); padding: 10px; background-color: rgb(255, 255, 170);"> 
       This is the <span style="border: 1px dashed rgb(0, 0, 255);">
                           <span style="color: rgb(136, 0, 0);">structure example</span>
                       </span> div. 
                       <div>This div is APPENDED</div>
</div>This text will go AFTER the example div.</div>
