How to get the innerHTML of selectable jquery element?

Question

Try

.text() or .html() instead of .innerHTML

Use .val() instead of .innerHTML for getting value of selected option

Use .text() for getting text of selected option

Thanks for correcting :)

$(function() {
        $("#select-image").selectable({
            selected: function( event, ui ) { 
                var $variable = $('.ui-selected').html(); 
                console.log($variable);
            }
        });
    });

                console.log($variable);
            }
