Question

我有一个带有范围验证器的表单：

<label class="required" for="price">price</label>
<input runat="server" id="price" name="price" type="text"  required="required"/>
<asp:RangeValidator runat="server" ControlToValidate="price" ErrorMessage="Must be between 0 and 15,000" MinimumValue="0" MaximumValue="15000"></asp:RangeValidator>

但它拒绝诸如'22'和'5'之类的值，但接受值'0'和'15,000'。最重要的是，它使我的表单的提交按钮对所有输入都没有响应。为什么范围验证器不起作用？

编辑：这是表单按钮

以及当我有rangevalidator时似乎没有触发的提交函数。如果我删除了rangevalidator，则此代码执行：

protected void btnSubmit_Click(object sender, EventArgs e)
        {

                formInputs.Visible = false;
                emailNotification.Visible = true;

                MailMessage mail = new MailMessage();
                mail.To.Add(emailField.Value);
                mail.From = new MailAddress("no-reply@gmail.com");
                mail.IsBodyHtml = true;
                mail.Subject = "Your Form has been submitted";
                mail.Body += "Location: ";
                mail.Body += location.SelectedValue + "<br>";
                mail.Body += " address: ";
                mail.Body += address.Value + "<br>";

                mail.Body += "price: " + price.Value + "<br>";
                mail.Body += "Date submitted: " + todaysDate.Value + "<br>";
                if (FileUploadControl.HasFile)
                {

                    string filename = Path.GetFileName(FileUploadControl.FileName);
                    FileUploadControl.SaveAs(Server.MapPath("~/") + filename);

                    mail.Attachments.Add(new Attachment(HttpContext.Current.Request.MapPath(filename)));
                }
                SmtpClient smtp = new SmtpClient(System.Configuration.ConfigurationManager.AppSettings["mailsetting"]);
                smtp.Send(mail);   
}

Answer 1

在验证器中输入Type =“Integer”，因为您没有给出类型。它可能将type作为字符串，这就是为什么它没有按预期验证。

您的验证器将被修改为

<asp:RangeValidator runat="server" Type="Integer" ControlToValidate="price" ErrorMessage="Must be between 0 and 15,000" MinimumValue="0" MaximumValue="15000"></asp:RangeValidator>

rangevalidator拒绝错误的值并使我的提交按钮无响应
