单选框值得选择

<input type="radio" name="pitype" value="LTE" <c:if test='${infoVO.batch_invest_type=="LTE"}'>checked</c:if>>LTE

<input type="radio" name="pitype" value="GSM" <c:if test='${infoVO.batch_invest_type=="GSM"}'>checked</c:if>>GSM

if 用于判断回显的值为被选项

$("input[name='pitype']").each(function(i,obj){

if($(obj).val()=='${infoVO.batch_invest_type}'){

$(obj).attr("checked,true");

}

})

循环判断单选框 哪一个是被选项
