再会

我正在使用带有母版页的 ASP.NET 页面。我想对输入字段（）进行实时表单验证。现在我看到的所有 tuts 和演示/插件都使用普通的 html 标签。我试图在我的表单上实现其中的一些，但它们不起作用。（我正在使用一个母版页面和一个普通的 aspx 网页表单......）

更新：问题用密码字段的 asp 控件替换输入标签...

原始输入元素

  <fieldset>
        <legend>Validating a complete form</legend>
        <p>
            <label for="firstname">Firstname</label>
            <input id="firstname" name="firstname" type="text" />
        </p>
        <p>
            <label for="lastname">Lastname</label>
            <input id="lastname" name="lastname" type="text" />
        </p>
        <p>
            <label for="username">Username</label>
            <input id="username" name="username" type="text" />
        </p>
        <p>
            <label for="password">Password</label>
            <input id="password" name="password" type="password" />
        </p>
        <p>
            <label for="confirm_password">Confirm password</label>
            <input id="confirm_password" name="confirm_password" type="password" />
        </p>
        <p>
            <label for="email">Email</label>
            <input id="email" name="email" type="email" />
        </p>
        <p>
            <label for="agree">Please agree to our policy</label>
            <input type="checkbox" class="checkbox" id="agree" name="agree" />
        </p>
        <p>
            <label for="newsletter">I'd like to receive the newsletter</label>
            <input type="checkbox" class="checkbox" id="newsletter" name="newsletter" />
        </p>

        <tr>
            <td class="tdRight"><asp:Label ID="LabelEmail" runat="server" Text="Email Address (to be used as username):"></asp:Label></td>
            <td class="tdLeft"><asp:TextBox name="email" type="email" ID="TextBoxEmail" runat="server" ClientIDMode="Static" TextMode="SingleLine" MaxLength="50"></asp:TextBox></td>
        </tr>
        <tr>
            <td class="tdRight"><asp:Label ID="Label1" runat="server" Text="Postal Address:"></asp:Label></td>
            <td class="tdLeft"><asp:TextBox ID="TextBoxPostal" runat="server" ClientIDMode="Static" TextMode="MultiLine" Rows="4" MaxLength="250"></asp:TextBox></td>
        </tr>

        <tr>
            <td class="tdRight"><asp:Label ID="LabelPassword" runat="server" Text="Password:"></asp:Label></td>
            <td class="tdLeft"><asp:TextBox name="password" type="password" ID="TextBoxPassword" runat="server" ClientIDMode="Static" TextMode="Password" MaxLength="50"></asp:TextBox></td>
        </tr>
        <tr>
            <td class="tdRight"><asp:Label ID="LabelConfirmPassword" runat="server" Text="Confirm Password:"></asp:Label></td>
            <td class="tdLeft"><asp:TextBox name="confirm_password" type="password" ID="TextBoxConfirmPassword" runat="server" ClientIDMode="Static" TextMode="Password" MaxLength="50"></asp:TextBox></td>
        </tr>

</fieldset>

我想用以下 ASP 控件替换上面的内容

        <tr>
            <td class="tdRight"><asp:Label ID="LabelEmail" runat="server" Text="Email Address (to be used as username):"></asp:Label></td>
            <td class="tdLeft"><asp:TextBox name="email" type="email" ID="TextBoxEmail" runat="server" ClientIDMode="Static" TextMode="SingleLine" MaxLength="50"></asp:TextBox></td>
        </tr>
        <tr>
            <td class="tdRight"><asp:Label ID="Label1" runat="server" Text="Postal Address:"></asp:Label></td>
            <td class="tdLeft"><asp:TextBox ID="TextBoxPostal" runat="server" ClientIDMode="Static" TextMode="MultiLine" Rows="4" MaxLength="250"></asp:TextBox></td>
        </tr>
        <tr>
            <td class="tdRight"><asp:Label ID="LabelPassword" runat="server" Text="Password:"></asp:Label></td>
            <td class="tdLeft"><asp:TextBox name="password" type="password" ID="TextBoxPassword" runat="server" ClientIDMode="Static" TextMode="Password" MaxLength="50"></asp:TextBox></td>
        </tr>
        <tr>
            <td class="tdRight"><asp:Label ID="LabelConfirmPassword" runat="server" Text="Confirm Password:"></asp:Label></td>
            <td class="tdLeft"><asp:TextBox name="confirm_password" type="password" ID="TextBoxConfirmPassword" runat="server" ClientIDMode="Static" TextMode="Password" MaxLength="50"></asp:TextBox></td>
        </tr>

现在一切正常，除了密码字段？为什么？此外，ID 并不重要，因为验证器在名称和类型字段上工作......

除非id您<form>的不是您的想法（查看您呈现的代码以验证这一点），否则您的表单验证代码应该可以工作。

您的代码的工作演示：http: //jsfiddle.net/b3QNY/

jQuery :

$(document).ready(function () {

    $('#form1').validate();

});

HTML：

<form id="form1">
    <fieldset>
        <legend>A simple comment form with submit validation and default messages</legend>
        <p>
            <label for="cname">Name</label>
<em>*</em>
            <input id="cname" name="name" size="25" class="required"
            minlength="2" />
        </p>
        <p>
            <label for="cemail">E-Mail</label>
<em>*</em>
            <input id="cemail" name="email" size="25" class="required email"
            />
        </p>
        <p>
            <label for="curl">URL</label>
<em> </em>
            <input id="curl" name="url" size="25" class="url"
            value="" />
        </p>
        <p>
            <label for="comment">Your comment</label>
<em>*</em>
            <textarea id="ccomment" name="comment" cols="22"
            class="required"></textarea>
        </p>
        <p>
            <input class="submit" type="submit" value="Submit" />
        </p>
    </fieldset>
</form>

我想我解决了 - 你必须为密码文本框创建自定义规则......由于某种原因，asp密码文本框的呈现效果不太好：

                <%= TextBoxPassword.UniqueID %>: {
                     required: true,
                     minlength: 5

                 },

                <%= TextBoxConfirmPassword.UniqueID %>: {
                    required: true,
                    minlength: 5,
                    equalTo: "#TextBoxPassword"
                },

表单验证现在可以工作了，除了 Visual Studio 呻吟 - 它以红色突出显示:并说：

“预期的标识符、字符串或数字”

那会是个问题吗？
