Question

首先让我解释一下我的情况。现在，我的表单的服务器端验证工作，现在我正在尝试让客户端验证为我的表单工作。目前我的表单有文本框和textarea，但只有文本区域使用客户端验证，我的文本框都没有。如果我点击提交按钮，使用fiddler我可以看到它仍在调用服务器来验证表单。任何人都可以帮助我理解为什么客户端验证将适用于我的textarea，但不适用于我的文本框。我是asp.net和C＃的新手，所以任何帮助都将不胜感激。

到目前为止，我已经在几个网站上寻求帮助：

MVC 2 Client side validation is not working

客户端验证 - Pietro Brambati的博客

Haacked.com - MVC 2自定义验证

Scott Gu的博客 - 模型验证

和其他几个我已经关闭了标签的人。我为无法将它们全部链接而道歉，但由于这是我的第一篇帖子，我只允许一个链接。这是我的代码，

从母版页：

        </div>
        <div style="padding-top: 10px">

            <input type="submit" value="Submit"/>
        </div>
</fieldset>
<%} %>
<%--</form>--%>

视图模型代码（正如您所看到的那样，第一个[Required]标签中包含AllowEmptyString，我从其他文章中读过，并告诉您我已经测试过它）：

public class HaveAQuestionViewModel
{
    [Required(AllowEmptyStrings = false, ErrorMessage = "*")]
    public string Name { get; set; }

    [Required(ErrorMessage = "*")]
    //this is my own regular expression that I created
    [RegularExpression("^[a-zA-Z0-9]+[\\.a-zA-Z0-9_]*[@][.a-zA-Z0-9]+[.]([a-z]{2,4})$", ErrorMessage = "*")]

    public string Email { get; set; }

    [Required(ErrorMessage = "*")]
    // Will take ddd-ddd-dddd or (ddd)ddd-dddd, or (ddd)-ddd-dddd
    [RegularExpression("[(]*([0-9]{3})[)]*[-]*([0-9]{3})[-]([0-9]{4})$" , ErrorMessage = "*")]
    public string Phone { get; set; }

    [Required(ErrorMessage = "*")]
    public string CommentsOrQuestions { get; set; }
}

我的控制器（这没关系，因为它假设验证客户端的所有内容。

从＆lt;％Html.EnableClientValidation（）生成的脚本; ％GT;

<script type="text/javascript">
//<![CDATA[
if (!window.mvcClientValidationMetadata) 
{ window.mvcClientValidationMetadata = []; }
window.mvcClientValidationMetadata.push(
{"Fields":[{"FieldName":"Name","ReplaceValidationMessageContents":true,

请帮助我，我正在运行VS 2010，并使用ASP.NET MVC 2.0。由于某种原因，文本区域将工作，而我的文本框都没有。

Answer 1

尝试大写每个文本框的ID。

客户端验证只有一半工作，适用于textarea，而不是文本框
