/**

*@file
|
|
*@brief Javascript object to manage ajax calls to
|
|
* save , input or delete data row.
|
|
*@details The callback must
|
|
respond with a XML file , the tag status for the result
|
|
and data the HTML code to display
|
|
*@param p_table_name the data table on which we're working
|
|
in javascript , to create an object to manipulate the table
|
|
version.
|
|
|
|
Example of code
|
|
@code
|
|
// Version will manage the table "version"
|
|
var version=new ManageTable("version");
|
|
|
|
// the file ajax_my.php will be called
|
|
version.set_callback("ajax_my.php");
|
|
|
|
// Add supplemental parameter to this file
|
|
version.param_add ({"plugin_code":"OIC"};
|
|
|
|
// Set the id of dialog box , table and tr prefix
|
|
version.set_control("dialbox1");
|
|
|
|
@endcode
|
|
|
|
|
|
The answer from ajax must be like this template
|
|
@verbatim
|
|
<xml>

<ctl> id of the control to update for diag.box, row </ctl>
|
|
<status> OK , FAIL ...</status>
