React代码标签未闭合错误排查求助（Hackathon场景）

你的代码存在标签未闭合、React语法不兼容、多余语法残留等问题，以下是具体修复点和完整修复后的代码：

核心错误点 #

• 第14行的<a>标签未闭合就直接跳转至form标签，导致后续DOM嵌套结构完全混乱
• 开头的<div class="container">和内部<footer>标签未闭合就开始form代码，破坏了页面层级
• React中必须用className替代HTML的class属性，避免与JavaScript关键字冲突
• 不能直接使用Jinja模板语法{{ url_for('xxx') }}，需替换为静态路径或React路由链接
• input标签在JSX中应为自闭合格式（<input ... />），无需额外的</input>标签
• 函数末尾存在多余的); }语法残留，需删除

额外说明 #

• 如果你使用React Router，建议将<a>标签替换为<Link>组件，避免页面全量刷新
• style属性在JSX中必须用对象格式（style={{ marginLeft: "50px" }}），已统一修改
• 提交按钮的value从"value"改为"Submit"，更符合用户操作习惯
