Hi, It's useful your extension. Thanks.

But my BO is done with prototype.js

so i did a version with prototype.
if it's useful for anyone, override the template like this :

design/admin/stylesheets/autocompelete/autocompletion.css



div.autocomplete {


 position:absolute;


 width:250px;


 background-color:white;


 border:1px solid #888;


 margin:0px;


 padding:0px;


}


div.autocomplete ul {


 list-style-type:none;


 margin:0px;


 padding:0px;


}


div.autocomplete ul li.selected { background-color: #eee;}


div.autocomplete ul li {


 list-style-type:none;


 display:block;


 margin:0;


 padding:1px;


 height:17px;


 cursor:pointer;


}

And i saw
// @TODO : add other reponse type handler :
// * XML
// * flat file

in the autocompete_ezkeywords.php

I wait the version with the handler flat file, beacause I should only override the template with my prototype.js, but not change the module.php

Hi !

Thanks for your feedback.
I have a question though : are the prototype libraries colliding with the YUI ones ? Or did you just want not to load several frameworks ?

Concerning the other TODOed back endhandlers : i thought i'd set up a real, INI based, back end system, loading the right handler automatically. Please do not hesitate to throw some specs around here.
Even better, become a member of this projects, and let's start off a short and brief specification document, placed somewhere in the SVN.

Let me know,

Hi, I don't want to load several frameworks and sometime there is conflit between them (just sometime).

for the endhandlers, your can add the OutputType in the ini

you see, my solution is flat file, and it works for php4 beacause no json.

you can use this, then it works for PHP4

Finally I am glad to join with you for the project.



if function_exists('json_encode')


{


   include_once( 'lib/json.php' );


   function json_encode($var)


   {


       $json = new Services_JSON();


       return $json->encode($var);


   }


}



and add a json librarie

/**


 * Converts to and from JSON format.


 *


 * JSON (JavaScript Object Notation) is a lightweight data-interchange


 * format. It is easy for humans to read and write. It is easy for machines


 * to parse and generate. It is based on a subset of the JavaScript


 * Programming Language, Standard ECMA-262 3rd Edition - December 1999.


 * This feature can also be found in Python. JSON is a text format that is


 * completely language independent but uses conventions that are familiar


 * to programmers of the C-family of languages, including C, C++, C#, Java,


 * JavaScript, Perl, TCL, and many others. These properties make JSON an


 * ideal data-interchange language.


 *


 * This package provides a simple encoder and decoder for JSON notation. It


 * is intended for use with client-side Javascript applications that make


 * use of HTTPRequest to perform server communication functions - data can


 * be encoded into JSON notation for use in a client-side javascript, or


 * decoded from incoming Javascript requests. JSON format is native to


 * Javascript, and can be directly eval()'ed with no further parsing


 * overhead


 *


 * All strings should be in ASCII or UTF-8 format!
