Disable fancyBox 2 from closing when clicking the background

Question

In fancyBox 2, is there a key/value I could set that will disable the lightbox from closing when the user clicks the background (semi-transparent black background)?

Answer 1

This will disable closing fancybox when clicking on the overlay (the semi-transparent background)

    fancyEls.fancybox({
        helpers : { 
            overlay : {
                closeClick: false
            } // prevents closing when clicking OUTSIDE fancybox
        }
    });

This will disable all default click methods of closing fancybox

    fancyEls.fancybox({
        closeBtn : false,
        closeClick : false,
        helpers : { 
            overlay : {
                closeClick: false
            } // prevents closing when clicking OUTSIDE fancybox
        },
        keys : {
            close: null
        } // prevents close when clicking escape button
    });

And this will do the same as well as disabling slideshow functionality

    fancyEls.fancybox({
        modal : true //If set to true, will disable navigation and closing  
    });
