Jquery input get value of self and sibling inputs on event -

i trying value of input (radio button) when clicked on , value of siblings. using jquery can value of siblings code below, can't think of how include value of selected element itself.

options = $(button).siblings('input:checkbox:checked').map(function () {       return this.value;     }).get();  

you can traverse parent element , find checked elements in ensure not considering current checkbox when unchecked:

$(button).parent().find('input:checkbox:checked').map(function () {   return this.value; }).get();
