  Hi,
 this works on a input element:

 var this_name = $(this).attr('name');

 so I'm trying to do the same to extract the code inside the onchange
 "attribute":

 var this_onchange = $(this).attr('onchange'); this won't work.

...
  but Firebug tells me that this_onchange is an event;
yepp that's right

...
  it does not contain the code. I need to do subsequent
string matching and
 replacement in this code. Please use a function call for this, and replace silly
the params:
$(this).unbind('change');
$(this).bind('change', function(e) {
 // your function call
 // something like:
 // pma_js_function_to_call(param1, param2, para,X)
});

Other solution is to work with a string, make your string replacement and
after this use the eval-function. Sample:
$(this).unbind('change');
$(this).bind('change', function(e) {
  eval(your_replaced_string);
});

But eval is devil:
The eval function (and its relatives, Function, setTimeout, and
setInterval) provide access to the JavaScript compiler. This is sometimes
necessary, but in most cases it indicates the presence of extremely bad
coding. The eval function is the most misused feature of JavaScript.
