实现代码块复制和会话搜索

新增功能：

代码块复制按钮
会话搜索

几乎所有的 AI 工具都支持这个功能，也非常常用，对于我们 CV 战士来说非常方便，哈哈哈

1）`web/src/App.vue`

import

csharp 复制代码

import { computed, ref, watch, onMounted, nextTick, h } from 'vue'

添加方法

javascript 复制代码

const copyCode = async code => {
  try {
    await navigator.clipboard.writeText(code || '')
    window.alert('代码已复制')
  } catch (e) {
    console.error(e)
    window.alert('复制失败')
  }
}

const renderer = new marked.Renderer()

renderer.code = ({ text, lang }) => {
  const language = lang || 'text'
  const escapedCode = (text || '')
    .replace(/&/g, '&amp;')
    .replace(/</g, '&lt;')
    .replace(/>/g, '&gt;')
    .replace(/"/g, '&quot;')

  return `
    <div class="code-block-wrap">
      <div class="code-block-header">
        <span class="code-lang">${language}</span>
        <button class="copy-code-btn" data-code="${escapedCode}">复制</button>
      </div>
      <pre><code class="language-${language}">${escapedCode}</code></pre>
    </div>
  `
}

const renderMarkdown = content => {
  const rawHtml = marked.parse(content || '', { renderer })
  return DOMPurify.sanitize(rawHtml)
}

新增状态

csharp 复制代码

const sessionKeyword = ref('')

新增计算属性

javascript 复制代码

const filteredSessions = computed(() => {
  const keyword = sessionKeyword.value.trim().toLowerCase()
  if (!keyword) return sessions.value

  return sessions.value.filter(item => {
    const titleMatch = (item.title || '').toLowerCase().includes(keyword)
    const messageMatch = (item.messages || []).some(msg =>
      (msg.content || '').toLowerCase().includes(keyword)
    )
    return titleMatch || messageMatch
  })
})

新增复制事件代理方法

javascript 复制代码

const handleChatBoxClick = event => {
  const target = event.target
  if (target?.classList?.contains('copy-code-btn')) {
    const code = target.getAttribute('data-code') || ''
    copyCode(
      code
        .replace(/&quot;/g, '"')
        .replace(/&gt;/g, '>')
        .replace(/&lt;/g, '<')
        .replace(/&amp;/g, '&')
    )
  }
}

`onMounted`

scss 复制代码

onMounted(() => {
  fetchMemories()
  scrollToBottom()

  if (chatBoxRef.value) {
    chatBoxRef.value.addEventListener('click', handleChatBoxClick)
  }
})

2）改模板

在左侧会话标题下面，加搜索框

新增

ini 复制代码

<input
  v-model="sessionKeyword"
  class="session-search"
  placeholder="搜索会话标题或消息内容"
/>

会话列表循环改成 filteredSessions

ini 复制代码

v-for="item in filteredSessions"

3）补充样式

css 复制代码

.session-search {
  width: 100%;
  box-sizing: border-box;
  border: 1px solid #d1d5db;
  border-radius: 10px;
  padding: 10px 12px;
  font-size: 14px;
  outline: none;
  margin-bottom: 12px;
}

.code-block-wrap {
  margin: 8px 0;
}

.code-block-header {
  display: flex;
  align-items: center;
  justify-content: space-between;
  background: #1f2937;
  color: #f9fafb;
  padding: 8px 12px;
  border-top-left-radius: 10px;
  border-top-right-radius: 10px;
  font-size: 12px;
}

.code-lang {
  opacity: 0.9;
}

.copy-code-btn {
  border: none;
  background: #374151;
  color: #fff;
  padding: 4px 10px;
  border-radius: 8px;
  font-size: 12px;
  cursor: pointer;
}

.copy-code-btn:hover {
  background: #4b5563;
}

.markdown-body :deep(.code-block-wrap pre) {
  margin: 0;
  border-top-left-radius: 0;
  border-top-right-radius: 0;
}

4）验证

验证代码复制

复制代码

请用 markdown 返回一个 Vue3 计数器示例，带代码块

然后点代码块右上角复制。

可以复制内容

验证会话搜索

左侧搜索框输入：

会话标题里的关键词
或某条消息内容里的关键词

实时过滤

目前样式有点不对劲改一下

模版加一层

ini 复制代码

<input
  v-model="sessionKeyword"
  class="session-search"
  placeholder="搜索会话标题或消息内容"
/>

<div class="session-list">
  <div
    v-for="item in filteredSessions"
    :key="item.id"
    :class="['session-item', currentSessionId === item.id ? 'active' : '']"
    @click="handleSwitchSession(item.id)"
  >
    <div class="session-top">
      <template v-if="editingSessionId === item.id">
        <input
          v-model="editingTitle"
          class="session-input"
          @click.stop
          @keydown.enter="handleRenameSession(item.id)"
          @blur="handleRenameSession(item.id)"
        />
      </template>
      <template v-else>
        <div class="session-title">{{ item.title }}</div>
      </template>

      <div class="session-actions">
        <span class="action-btn" @click.stop="handleStartRename(item)">改名</span>
        <span class="action-btn delete" @click.stop="handleDeleteSession(item.id)">删除</span>
      </div>
    </div>
    <div class="session-time">{{ formatTime(item.updatedAt) }}</div>
  </div>
</div>
