$("input[name=PType]").bind(‘click‘, function () {
                if ($(this).prop("checked")) {
                    redio1 = $(this).val();
                }
            });

//PType  是选择项的name  redio1 变量 存单选中的选项

function someCheck() {
            var alertinf = ""
            var clist = document.getElementsByName("ck"); //ck是复选框选择项的name
            for (i = 0; i < clist.length; i++) {
                if (clist[i].checked == true) {
                    alertinf += clist[i].value + ",";
                }
            }
            WYTD =  alertinf;
