i've found solution convert enum camelcase, it's not elegant. var underscoretocamelcase = function(str) { str = (str === undefined || str === null) ? '' : str; str = str.replace(/_/g, " ").tolowercase(); return str.replace(/(?:^\w|[a-z]|\b\w|\s+)/g, function(match, index) { if (+match === 0) return ""; return index == 0 ? match.tolowercase() : match.touppercase(); }); } so, if str my_enum_string return myenumstring. there must way achieve single regex match? try this: var underscoretocamelcase = function(str) { return str.tolowercase() .replace(/_+(\w|$)/g, function ($$, $1) { return $1.touppercase(); }); }

with code below selecting checkboxes , radio buttons send them array. var options = []; $('.option input[type="checkbox"]:checked, .option input[type=radio]:checked').each(function() { options.push($(this).val()); }); var options_checked = options.join(','); there single radio buttons have parent class sass_syntax , of course selected. don't want select them if class sass_syntax hidden ( display: none ). how can this? you can exclude them using .not() filter var options = $('.option input[type="checkbox"]:checked, .option input[type=radio]:checked').not('.sass_syntax:hidden input').map(function() { return $(this).val(); }).get(); var options_checked = options.join(',');
