我找到了一个简单的 Bootstrap 验证程序源代码，但是“form”标签中的元素数据切换不支持所以我的网页无法执行验证操作，我必须在 Css 文件中写下数据切换，但只有“支持数据绑定(bind)”元素。我刚接触这些 css 和 jquery，我的核心是 java/android，所以这可能是一个基本问题，我希望这不会打扰你们。 这是我的源代码:

我认为您应该将 jQuery 的源代码放在 bootstrap js 的源代码之前。像这样:
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.0/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.0/js/bootstrap.min.js"></script>
</head>
<body>
<form data-toggle="validator" role="form">
<div class="form-group">
<label for="inputName" class="control-label">Name</label>
<input type="text" class="form-control" id="inputName" placeholder="Cina Saffary" required>

<input type="text" pattern="^[_A-z0-9]{1,}$" maxlength="15" class="form-control" id="inputTwitter" placeholder="1000hz" required>
</div>
<span class="glyphicon form-control-feedback" aria-hidden="true"></span>
<div class="help-block with-errors">Hey look, this one has feedback icons!</div>
