C# 使浏览器忽略回发时的验证,即;“以前的”;

C# 使浏览器忽略回发时的验证,即;“以前的”;,c#,asp.net,forms,C#,Asp.net,Forms,我正在使用客户端验证 <asp:UpdatePanel ID="UpdatePanel1" UpdateMode="Conditional" runat="server"> <ContentTemplate> <asp:TextBox runat="server" ID="Customer_Email" name="Email" type="email" required="" /> <!-- more fields -->

我正在使用客户端验证

<asp:UpdatePanel ID="UpdatePanel1" UpdateMode="Conditional" runat="server">
  <ContentTemplate>
    <asp:TextBox runat="server" ID="Customer_Email" name="Email" type="email" required="" />
    <!-- more fields -->
    <asp:Button runat="server" ID="prevbutton" Text="Previous" OnClick="prevbutton_Click" />
    <asp:Button runat="server" ID="nextbutton" Text="Next" OnClick="nextbutton_Click" />
  </ContentTemplate>
</asp:UpdatePanel>
按按钮,无变化;Chrome仍会提醒用户该字段是必需的

编辑2

生成的html是

<input name="ctl00$cphContentMiddleRight$Customer_Email" 
id="ctl00_cphContentMiddleRight_Customer_Email" 
class="form-control input-md" 
type="email" required="">

<input type="submit" name="ctl00$cphContentMiddleRight$prevbutton_2" 
value="Previous" id="ctl00_cphContentMiddleRight_prevbutton_2" class="btn btn-default">


我看不到任何东西告诉浏览器不要进行本机验证。

设置
会导致按钮上的验证
为false

<asp:Button runat="server" ID="prevbutton" Text="Previous" OnClick="prevbutton_Click" CausesValidation="false" />

不起作用;它不包含在生成的html中,因此浏览器看不到它。什么内容不包含在html中?因为我几乎可以保证,在使用aspnet验证器时,这是可行的。添加
required
在所有浏览器上都不起作用,aspnet不支持这一点。切换到aspnet验证程序或创建自己的jQuery表单验证函数。我已使用自定义解决方案更新了我的答案。但是,我仍然建议使用
RequiredFieldValidator
<asp:Button runat="server" ID="prevbutton" Text="Previous" OnClick="prevbutton_Click" CausesValidation="false" />
<asp:Button runat="server" ID="prevbutton" Text="Previous" OnClientClick="removeValidation()" />

<script type="text/javascript">
    function removeValidation() {
        $("#<%= Customer_Email.ClientID %>").removeAttr("required");
    }
</script>
