2.1 功能说明

检测文案中的广告违禁词并高亮，支持自定义词库

2.1.1 使用指南

功能说明

把文案粘贴进来，一键找出其中的广告法极限词、医疗夸大用语、金融违规承诺等风险词汇， 按类别用不同颜色标注出位置，并给出命中统计和替换后的安全文案。词库内置在页面中，检测过程不联网、不上传。

内置词库

共 {{ BUILTIN_WORDS.length }} 个词，覆盖 {{ CATEGORIES.length }} 个类别：

{{ c.label }}：{{ c.desc }}

使用方法

1. 在左侧输入或粘贴文案，检测结果实时更新；
2. 右上方查看命中总数与分类分布，点击类别标签可以只看某一类；
3. 在「替换预览」中调整替换字符与替换方式，复制处理后的安全文案；
4. 如需检测行业特有词汇，在「自定义词」中按行或用逗号分隔追加，仅在当前页面生效，刷新即失效。

关于广告法极限词

《广告法》第九条禁止使用"国家级""最高级""最佳"等表示最高等级、最佳效果的用语。实际执法中，能提供权威第三方评测依据、或明确限定时间与范围的表述（例如"2025 年双十一本店销量第一"）风险较低，需结合语境判断。

结果仅供参考

本工具基于关键词匹配，无法理解上下文语义，可能出现误报（例如"最后一天"中的"最后"、"绝对值"中的"绝对"）与漏报。正式对外发布前请结合人工复核，或接入专业的内容合规审核服务。

涉政类词汇未内置，此类内容请以主管部门与平台方提供的官方词库为准。

2.2 代码实现

2.2.1 组件结构

本工具是一个基于 Vue 3 <script setup> 语法的单文件组件（SFC），统一包裹在 ToolPageShell 组件内，由它提供页面标题、工具 ID、分类与「使用指南」插槽等通用外壳；核心业务逻辑（响应式状态、计算属性、事件处理函数）全部写在 <script setup> 中，输入/输出通过 el-input、el-button 等 Element Plus 组件与用户交互，所有数据均在浏览器本地处理，不会上传服务器。

2.2.2 核心逻辑概览

<script setup> 中定义的主要函数/方法：

• escapeHtml()
• copyReplaced()
• downloadReplaced()
• loadSample()

2.2.3 关键实现代码

以下是该工具的完整 <script setup> 实现（核心代码）。模板（<template>）与样式（<style>）已省略。

import {computed, ref} from 'vue'
import {ElMessage} from 'element-plus'
import ToolPageShell from '@/components/ToolPageShell.vue'
