|

*
|
||||
* The usage of the SimpleAjax extensions is very easy. The extension provides
|

* the hook $GLOBALS['TL_HOOKS']['simpleAjax'] for extension developers. You
|
||||
* simply have to register your class/method and the extension will call
|
||||
* your class if there is an incomming ajax request.
|
||||
*
|
||||
* You simply have to deside if it's an ajax request for your module and return
|
||||
* the data you want.
|
||||
*
|
||||
* There are a few thinks you should know about the extension:
|
||||
* * YOU have the full controll over the response. That also means
|
||||
* that you have to set the correct header.
|
||||
* * YOU have to terminate the request after you have send the response.
|
||||
* * If the ajax request is not for your method you simply have nothing to
|
||||
* * return.
|
||||
*
|
||||
*
|
||||
* Usage
|
