var abc = $('#tree').find('li [data-role="checkbox"] input[type="checkbox"], li [data-role="node"] input[type="checkbox"]'); var result=[]; $.each(abc, (k,v)=> { var checkbox = $(v); console.log(checkbox.checkbox('state')) if (checkbox.checkbox('state') === 'checked' || checkbox.checkbox('state') === "indeterminate") { result.push(checkbox.closest('li').data('id')); } });
