单选组radio: $("input[@type=radio][@checked]").val();
单选组radio: $("input[@type=radio]").attr("checked",'2');//设置value=2的项目为当前选中项
获取一组radio被选中项的值
var item = $('input[@name=items][@checked]').val();
radio单选组的第二个元素为当前选中值
$('input[@name=items]').get(1).checked = true
单选组 radio: $("input[@type=radio]").attr("checked",'2');//设置value=2的项目为当前选中项
jquery老的版本
var_name = $("input[@name='radio_name']:checked").val();
jquery 1.3以后的版本
var_name = $("input[name='radio_name']:checked").val();
看个获取radio值的jquery实例
