Disable all form elements but one
<p>I use the following to disable all form elements within a table row:</p>

<pre><code>$(".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);
    }
});
</code></pre>

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