ASP.Net验证摘要导致跳转到首页 [英] ASP.Net validation summary causes page to jump to top

问题描述

我有一个简单的形式与一些必填字段验证器和一个验证摘要控制。当我提交表单时，的客户的验证会导致形式跳转到页面顶部。如果我删除了验证摘要，页面不动。

I have a simple form with a few required field validators and a validation summary control. When I submit the form, the client validation will cause the form to jump to the top of the page. If i remove the validation summary, the page does not move.

下面有一个简单的例子：

Heres a quick example:

<asp:TextBox ID="test" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="testrequired" runat="server" ControlToValidate="test">*</asp:RequiredFieldValidator>
<asp:ValidationSummary ID="summary" runat="server" />
<asp:Button ID="submit" runat="server" Text="submit" />

我试过设置 SetFocusOnError =真正的在必填字段验证器和 MaintainScrollPositionOnPostback =真正的为笑声 - 尽管这不是一个回发 - 没有任何运气。是否有此问题的已知的解决方案？

I've tried setting SetFocusOnError="true" in the required field validator and MaintainScrollPositionOnPostback="true" for giggles - even though this isn't a postback - without any luck. Is there a known solution for this problem?

编辑：

我发现通过WebResource.axd的生成JS的问题。似乎归结为在 ValidationSummaryOnSubmit（）函数一行。

I've found the problem in the js generated by WebResource.axd. Seems to come down to a single line in the ValidationSummaryOnSubmit() function.

line 534: window.scrollTo(0,0);

如何删除或任何想法绕过此？

Any ideas on how to remove or bypass this?

EDIT2：

快速变通暂时

• 设置 EnableClientScript =假所有验证控件（禁用客户端验证）


• 设置 MaintainScrollPositionOnPostback =在Page指令真实

• set EnableClientScript="false" for all validation controls (disabling client validation)
• set MaintainScrollPositionOnPostback="true" in Page directive

仍然希望一个客户端解决方案...

Still hoping for a client side solution...

EDIT3：

这似乎是一个更好的解决办法是只覆盖 window.scrollTo（）功能，以便当验证脚本调用它什么都不做：

It seems a better work around is to just override the window.scrollTo() function so that it does nothing when called by the validation script:

<script type="text/javascript">
    window.scrollTo = function() { }
</script>

添加上述页面上的任何地方留下的机智客户端验证，但禁用 window.scrollTo（）方法在整个页面

推荐答案

有两种可能的变通：

禁用客户端验证并跳转到更正后的位置回：

Disable client validation and jump to correct position on post back:

* set EnableClientScript="false" for all validation controls (disabling client validation)
* set MaintainScrollPositionOnPostback="true" in Page directive

禁用scrollTo功能在JavaScript：

Disable the scrollTo function in javascript:

<script type="text/javascript">
    window.scrollTo = function() { }
</script>
