验证策略？ [英] validation strategy?

问题描述

我需要确保三个电话号码字段中至少有一个具有值

（requiredfield）但是我不确定如何在没有服务器的情况下实现这一点

边逻辑。有没有办法使用验证控件来做到这一点？


谢谢。

I need to insure that at least one of three phone number fields has a value
(requiredfield) but I''m not sure of a way to implement this without server
side logic. Is there a way to use the validation controls to do this?

Thanks.

推荐答案

我是不确定是否有办法使用验证控件

而不是使用CustomValidator控件。 CustomValidator控件

确实要求你编写服务器端验证代码，但如果你编写了一个

客户端JavaScript函数，你可以设置

ClientValidationFunction属性允许启用JavaScript的浏览器

执行验证客户端。我自己从未使用过这个属性，

但听起来不应该太难。祝你好运！

I am not sure if there is a way to do that using the validation controls
other than using the CustomValidator Control. The CustomValidator Control
does require you to write server-side validation code, but if you write a
client-side JavaScript function as well you can set the
ClientValidationFunction property to allow JavaScript enabled browsers to
perform the validation client-side. I have never used this property myself,
but it doesn''t sound like it should be too hard. Good Luck!

聪明的解决方法Phillip！


但是我正在寻找一种方法来确保三个

文本框中至少有一个文本框中有一个值而没有指定为强制字段，如

这些在表单的不同部分 - 例如工作领域与家庭领域。


我现在有服务器端验证工作，但由于它没有使用

验证控制错误消息没有'一旦用户选择

离开现场，就会消失。


我想我将不得不刷新我的javascript！


感谢您的建议。

Clever workaround Phillip!

but I''m looking for a way to just insure that at least one of three
textboxes has a value in it without designating on as the mandatory field, as
these are in different sections of the form - e.g. work fields vs home fields.

I have a server side validation working now, but since it doesn''t use
validation controls the error message doesn''t disappear once the user tabs
out of the field.

I guess I''m going to have to brush up on my javascript!

Thanks for your suggestion.
