Question

Does anyone know how to check if the called ui (custom) has also options input or using the defaults?

For example:

$('#selector').myUI();//does not have options.
$('#selector').myUI({option:'foo',{op:'bar'}});//ui has options.
$('#selector').myUI('value');//ui has options.

So if I was on:

(function($) {
    $.widget("ui.myUI", {
       options = this.options;
       //check if options have been entered or the default values have been used?
    })

});

To check whether an option has been specified, you can write

if (options.hasOwnProperty('someProperty'))
