页面中的radio选择适合的非空判断

 var cyjb=$('input:radio[name="jcrwModel.cyjb"]:checked').val();

               if(cyjb==null||cyjb==''){

                     alert("抽样级别未选择");

                     return false;

                 }

             var cypz=$('input:radio[name="jcrwModel.cypz"]:checked').val();

               if(cypz==null||cypz==''){

                     alert("抽未选择");

                     return false;

                 }
