Disable Buttons in jQuery Mobile

UPDATE:

Since this question still gets a lot of hits I’m also adding the current jQM Docs on how to disable the button:

• http://jquerymobile.com/demos/1.2.0/docs/buttons/buttons-methods.html

Updated Examples:

enable enable a disabled form button

$('[type="submit"]').button('enable');  

disable disable a form button

$('[type="submit"]').button('disable'); 

refresh update the form button
If you manipulate a form button via
JavaScript, you must call the refresh method on it to update the
visual styling.

$('[type="submit"]').button('refresh');

UPDATE:

Using @naugtur example below: http://jsfiddle.net/XRjh2/16/

UPDATE #2:

Link button example:

• http://jsfiddle.net/gRLYQ/6/

JS

var clicked = false;

$('#myButton').click(function() {
    if(clicked === false) {
        $(this).addClass('ui-disabled');
        clicked = true;
        alert('Button is now disabled');
    } 
});

$('#enableButton').click(function() {
    $('#myButton').removeClass('ui-disabled');
    clicked = false; 
});

HTML

<div data-role="page" id="home">
    <div data-role="content">

        <a href="#" data-role="button" id="myButton">Click button</a>
        <a href="#" data-role="button" id="enableButton">Enable button</a>

    </div>
</div>

NOTE: – http://jquerymobile.com/demos/1.0rc2/docs/buttons/buttons-types.html

Links styled like buttons have all the same visual options as true
form-based buttons below, but there are a few important differences.
Link-based buttons aren’t part of the button plugin and only just use
the underlying buttonMarkup plugin to generate the button styles so
the form button methods (enable, disable, refresh) aren’t supported.
If you need to disable a link-based button (or any element), it’s
possible to apply the disabled class ui-disabled yourself with
JavaScript to achieve the same effect.
