[jQuery] Test if BlockUI is blocking an element

[jQuery] Test if BlockUI is blocking an element


Hello,
Is there a way to test if blockUI is currently blocking a specific
element?
I am doing this:
$('#middle_right').block({
    message: this.loader_msg,
css:{
                border: '2px solid #ddd',
                backgroundColor:'#fff'
            },
overlayCSS:{
             backgroundColor:'#eee',
             opacity: '0.6'
            }
});
and want to create a function like this with jquery:
this.is_loading = function() {
if(document.getElementById('module_menu_loader').style.display
== 'block') {
return 'both';
} else if(document.getElementById
('content_loader').style.display == 'block') {
return 'single';
} else {
return false;
}
}
Thanks
