Jquery UI tooltip on disabled button

Question

I am trying to show tooltip for a disabled button. I am not sure if jquery events fire for disabled elements but I am trying to check if I can show tool tip for disabled items. My example is here

<p>Your age:
    <input id="age" title="We ask for your age only for statistical purposes.">
</p>
<p>
    <input type="button" title="This a test enabled button." value="hover me please">
</p>
    <p>
  <input type="button" disabled="disabled" title="This a test disabled button." value="hover me please">   </p>



$(function () {
    $(document).tooltip({
        position: {
            my: "center bottom-20",
            at: "center top",
            using: function (position, feedback) {
                $(this).css(position);
                $("<div>")
                    .addClass("arrow")
                    .addClass(feedback.vertical)
                    .addClass(feedback.horizontal)
                    .appendTo(this);
            }
        }
    });
});

Looks like it's not guaranteed to work properly.

See the doc (http://api.jqueryui.com/tooltip/):

In general, disabled elements do not trigger any DOM events. Therefore, it is not possible to properly control tooltips for disabled elements, since we need to listen to events to determine when to show and hide the tooltip. As a result, jQuery UI does not guarantee any level of support for tooltips attached to disabled elements. Unfortunately, this means that if you require tooltips on disabled elements, you may end up with a mixture of native tooltips and jQuery UI tooltips.

EDIT: One way to go around this would be to, instead of setting the button to disabled, style it so that it looks like it was disabled. If it's a simple button, that's all you have to do, if it's a submit button, you'll also have to prevent it submitting the form.

EDIT #2: I gave the above workaround a try and it appears opacity:0.5 pretty much does the job (source: tjvantoll.com):

.disabled-button {
    opacity: 0.5;
}
