js賦值：

var ele1 = document.getElementsByName("
 
radio1");
ele1[0].checked=true;

jquery賦值

$("input[type=‘radio1‘]").eq(0).prop("checked",true);//默認選中有

$("input[name=‘radio1‘][value=‘2‘]").attr("checked",true); 

獲取當前用戶選中的值

function getRadioRes(className) {
                var rdsObj = document.getElementsByName(className);
                var chackVal = null
 
;
                for(i = 0; i < rdsObj.length; i++) {
                    if (rdsObj[i].checked) {
                        chackVal = rdsObj[i].value;
                    }
                }
                return chackVal;
            }


var regType = getRadioRes("radio1");

後臺獲取radio的值，給頁面添加默認值 【js， query】
