Looping through a set of IDs to set JQuery triggers on that pass a parameter to a function, such that it works

Corrected JavaScript to work for first variable in list (product) as well as second (rental).

Very novice javascript mistake, i used the same variable in the definition of the id selector and then in the function triggered on a change to that id selector (which was on a form element in each case). Of course, when that is triggered, the variable is not the same as it was in the first rotation, but rather whatever it was in the last. (This was defined in a for loop.) The solution i used was to get the id from the this object and parse it to get the original variable string back to pass into the action function.

There are probably better ways.

The problem is easy to see:

alert($(this).attr("id"));
alert(producttype);

Gives edit-attributes-1-purchase
and rental
respectively when clicking on a purchase link-- because rental is what the producttype variable is after all the looping is done. So even though the trigger is set up correctly for purchase, the code that it triggers, when it triggers it, has the wrong parameter.

The working main part of the function:

$(document).ready(function() {
      var str = $(this).attr("id").substr(18); // Remove 'edit-attributes-1-'.
      AgaricGenartsCommerce.formUpdate(str, true);
    });
    // We always have to check price, but in these cases can skip showhide.
    $('#edit-qty-' + producttype).change(function() {
      var str = $(this).attr("id").substr(9); // Remove 'edit-qty-'.
      AgaricGenartsCommerce.formUpdate(str);
    });
    if (producttype == 'rental') {
      $('#edit-attributes-10').change(function() {
        AgaricGenartsCommerce.formUpdate(producttype);
      });
    }
  }
});

jquery print this object
Couldn't see anything useful in this object. Could i assign something to it?

var string = '';
for(var a in this){
  string = string + a + ': ' + this[a] + " \n";
  // a would be the key ie 'title'
  // obj[a] would get the value ie 'mytitle'
}
alert('this: ' + string);
