change selected radio jquery
Say you had radio buttons like these, for example: <input type='radio' name='gender' value='Male'> <input type='radio' name='gender' value='Female'> And you wanted to check the one with a value of "Male" onload if no radio is checked: $(function() { var $radios = $('input:radio[name=gender]'); if($radios.is(':checked') === false) { $radios.filter('[value=Male]').prop('checked', true); } });
