I use the following to disable all form elements within a table row:

```
$(".chkbx").change(function(){
    var $this  = $(this);
    if ($this.is(":checked")) {
        $this.closest("tr").find(":input").attr("disabled", false);
    } else {
        $this.closest("tr").find(":input").attr("disabled", true);
    }
});

```

Which it does great. The problem -- it disables ALL, including **.chkbx**. I need to keep the checkbox with this class (chkbx) always enabled. How do I exclude it from the function?
