function ChkForm(){var Form = document.TestForm;var Validator = new ValidatorClass();Validator.ChkName(Form.ZD_UserName,"订货人姓名不合法!");Validator.ChkEmail(Form.ZD_Email,"订货人邮件地址不合法!");Validator.ChkPlace(Form.ZD_Province,"订货人省份不合法!");Validator.ChkPlace(Form.ZD_City,"订货人城市不合法!");Validator.ChkAddress(Form.ZD_Address,"订货人地址不合法!");Validator.ChkPostNumber(Form.ZD_Zip,"订货人邮编不合法!");Validator.ChkMobile(Form.ZD_Mobile,"订货人移动电话不合法!");Validator.ChkPhone(Form.ZD_Phone,"订货人固定电话不合法!");Validator.Submit(Form,"验证成功！");}
