JQuery Validation 在 asp .net 中的母版页上不起作用答案

【问题标题】：JQuery Validation not working on master page in asp .netJQuery Validation 在 asp .net 中的母版页上不起作用

【问题描述】：

我有一些带有一个母版页的 .aspx 页面。我想对 .aspx 页面上的所有控件进行客户端验证。为此，我正在使用 jquery 验证。（ashley 在 papermashup.com 教程上验证的番茄酱插件）

它在 .aspx 页面“无”母版页上正常工作。但是当我在母版页上使用相同的代码和链接文件时，它就不起作用了。

没有母版页的代码

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="validation_demo.aspx.cs" Inherits="webpages_validation_demo" %>

带有母版页的代码：

母版页：

    </html>

aspx pge with master page:

    <%@ Page Title="" Language="C#" MasterPageFile="~/webpages/Master_demo.master" AutoEventWireup="true" CodeFile="demo_validation1.aspx.cs" Inherits="webpages_demo_validation1" %>

【解决方案1】：

我认为您缺少母版页上带有注册 ID 的表单元素

-- 更新

好的

将您的输入更改为以下内容

 <input type="text" data-validate="validate(required ,number, minlength(10) ,maxlength(10))"  name="number" />

在这里重新下载番茄酱插件

https://github.com/mustardamus/ketchup-plugin/downloads

并使用以下行

<script type="text/javascript" src="js/jquery.ketchup.all.min.js"></script>

而不是

<script type="text/javascript" src="../js/jquery.ketchup.js"></script>
    <script type="text/javascript" src="../js/jquery.ketchup.messages.js"></script>
    <script type="text/javascript" src="../js/jquery.ketchup.validations.basic.js"></script>

这对我有用。

【讨论】：

确保 css 引用指向正确的路径
是的，这是正确的，但我使用的是 data-validate="validate(required)" 而不是 Class="validate(required)"
