}); 

2.iPhoto (ish)

            border: 'none', 
            padding: '15px', 
            backgroundColor: '#000', 
            '-webkit-border-radius': '10px',

});

        setTimeout($.unblockUI, 2000); 
    }); 
}); 

4.Tall Content

$(document).ready(function() { 
    $('#demo4').click(function() { 
        $.blockUI({ 
            message: $('#tallContent'), 
            css: { top: '20%' } 
        }); 
 
        setTimeout($.unblockUI, 2000); 
    }); 
}); 

5.Image Box

$(document).ready(function() { 
    $('#demo5').click(function() { 
        $.blockUI({ 
            message: $('#displayBox'), 
            css: { 
                top:  ($(window).height() - 400) /2 + 'px', 
                left: ($(window).width() - 400) /2 + 'px', 
                 '400px' 
            } 
        }); 
 
        setTimeout($.unblockUI, 2000); 
    }); 
}); 

6.Non-centered message

$(document).ready(function() { 
    $('#demo6').click(function() { 
        $.blockUI({ 
            centerY: 0, 
            css: { top: '10px', left: '', right: '10px' } 
        }); 
 
        setTimeout($.unblockUI, 2000); 
    }); 
});

$(document).ready(function() { 
    $('#demo7').click(function() { 
        $.blockUI({ message: null }); 
 
        setTimeout($.unblockUI, 2000); 
    }); 
}); 

8.onUnblock callback (useful when using fadeOut option as it is invoked when all the blocking elements have been removed)

$(document).ready(function() { 
    $('#demo8').click(function() { 
        $.blockUI(); 
 
        setTimeout(function() { 
            $.unblockUI({ 
                onUnblock: function(){ alert('onUnblock'); } 
            }); 
        }, 2000); 
    }); 
}); 

9.Click overlay to unblock (This demo will not automatically unblock, you must click the overlay.)

$(document).ready(function() { 
    $('#demo9').click(function() { 
        $.blockUI(); 
        $('.blockOverlay').attr('title','Click to unblock').click($.unblockUI); 
    }); 
}); 

10.Auto-Unblock Sets a timer to unblock after a specified timeout.

$(document).ready(function() { 
    $('#demo10').click(function() { 
        $.blockUI({ 
            message: '<h1>Auto-Unblock!</h1>', 
            timeout: 2000 
        }); 
    }); 
}); 

11.Growl (the hard way)

$(document).ready(function() { 
    $('#demo11').click(function() { 
        $.blockUI({ 
            message: $('div.growlUI'), 
            fadeIn: 700, 
            fadeOut: 700, 
            timeout: 2000, 
            showOverlay: false, 
            centerY: false, 
            css: { 
                 '350px', 
                top: '10px', 
                left: '', 
                right: '10px', 
                border: 'none', 
                padding: '5px', 
                backgroundColor: '#000', 
                '-webkit-border-radius': '10px', 
                '-moz-border-radius': '10px', 
                opacity: .6, 
                color: '#fff' 
            } 
        }); 
    }); 
});

12.Growl (the easy way)

$(document).ready(function() { 
   $('#demo12').click(function() { 
       $.growlUI('Growl Notification', 'Have a nice day!'); 
   }); 
}); 

The two growl examples above also make use of the following external CSS:

div.growlUI { background: url(check48.png) no-repeat 10px 10px }
div.growlUI h1, div.growlUI h2 {
    color: white; padding: 5px 5px 5px 75px; text-align: left
}

Note: For a more full-featured "growl" implementation, check out the excellent jGrowl plugin by Stan Lemon.

            title:    'This is your title', 
            message:  '<p>This is your message.</p>', 
            timeout:   2000 
        }); 
    });    
});

    $('#demo14').click(function() { 
        $.blockUI({ 
            fadeIn: 1000,

            onBlock: function() { 
                alert('Page is now blocked; fadeIn complete'); 
            } 
        }); 
    });    
});
