unmatched products are skipped. --- ### 字段规则配置 / Field Rule Configuration **中文** 每个字段规则包含： | 配置项 | 说明 | | ------------ | ----------------------------------------------- | | 字段名称 | 导出 Excel 的列标题 | | CSS 选择器 | 支持多行（按顺序匹配第一个命中的） | | 字段类型 | 文本 / 数字 / 图片 / 图片列表 / HTML / 元素属性 | | 是否为列表 | 提取多个值（图片列表自动勾选） | | 图片存储方式 | 无 / 主图 / 详情图 | | 后处理函数 | JavaScript 函数，对提取结果进行二次处理 | | 字段宽度 | 控制 Excel 导出时该列的宽度 | 支持： - **元素拾取器**：点击按钮后在页面上点选元素，自动生成选择器 - **测试匹配**：实时在当前页面验证选择器命中情况 - **拖拽排序**：左侧手柄拖动调整字段顺序 **English** Each field rule includes: | Setting | Description | | --------------------- | ----------------------------------------------------- | | Field Name | Column header in the exported Excel | | CSS Selector | Multi-line supported (first match wins) | | Field Type | Text / Number / Image / Image List / HTML / Attribute | | Is List | Extract multiple values (auto-checked for Image List) | | Image Storage | None / Main Image / Description Image | | Post-process Function | JavaScript to transform the extracted value | | Column Width | Controls Excel column width on export | Features: - **Element Picker**: Click to pick an element on the page; selector is auto-generated - **Test Match**: Instantly verify the selector against the current page - **Drag to Reorder**: Drag the left handle to rearrange fields --- ### 高级设置 / Advanced Settings **中文** | 配置项 | 说明 | | ------------ | --------------------------------------------- | | 页面加载判定 | 元素出现 / 元素消失，配合选择器和超时时间使用 | | 自动滚动 | 采集前自动滚动页面，触发懒加载内容 | | 前置脚本 | 在提取数据前执行自定义 JS（支持 async/await） | **English** | Setting | Description | | -------------- | ----------------------------------------------------------------- | | Load Condition | Wait for element to appear / disappear, with selector and timeout | | Auto Scroll | Scroll the page before extraction to trigger lazy-loaded content | | Pre-script | Run custom JS before data extraction (supports async/await) | --- ## 步骤三：执行采集 / Step 3: Run Scraping **中文** | 配置项 | 说明 | | ------------ | ------------------------------------------------------------------------ | | 抓取间隔 | 相邻两个商品之间的等待时间（秒），建议 ≥ 5 | | 图片命名规则 | 主图 / 详情图的文件名格式（支持 `{sku}`、`{index}`、`{ext}` 变量） | | 图片存储方式 | 合并模式（主图/详情图共用目录）/ 分离模式（按 SKU 子目录） | 操作按钮：**开始 → 暂停 → 继续 → 停止** 右侧实时日志面板显示每条商品的采集状态、图片下载进度、截图结果等。 导出目录结构预览（第三个 Tab 底部）会实时反映当前配置，包括是否显示 `screenshots/` 文件夹。 **English** | Setting | Description | | --------------- | ------------------------------------------------------------------------------------------- | | Scrape Interval | Wait time (seconds) between products; recommended ≥ 5 | | Image Naming | File name pattern for main/description images (`{sku}`, `{index}`, `{ext}` variables) | | Image Storage | Merged (shared dirs) / Separated (per-SKU subdirectories) | Controls: **Start → Pause → Resume → Stop** The real-time log panel on the right shows scraping status, image download progress, and screenshot results for each product. The directory structure preview (bottom of Step 3 tab) updates live based on settings, including whether `screenshots/` is shown. --- ## 截图功能 / Screenshot Feature **中文** 截图设置位于**详情页规则 Tab** 的字段列表下方，按规则集独立配置。 ### 启用截图 勾选**启用截图**后，每个详情页抓取完成后自动截图。 ### 截图模式 | 模式 | 说明 | | -------------------------------- | --------------------------------------------------------- | | 可见区域（默认） | 截取当前浏览器视口 | | 全页面 | 截取完整页面（含滚动区域），使用 Chrome DevTools Protocol | | 滚动到指定元素，然后截取可见区域 | 滚动到目标元素后截取视口 | | 只截取指定元素 | 精确裁剪到元素边界，不含周围内容 | > "全页面"和"只截取指定元素"模式需要 `debugger` 权限，截图完成后立即释放。 ### 元素选择器 - 填写 CSS 选择器，指定目标元素 - 点击**拾取器按钮**（准星图标）从页面上直接选取元素 - 点击**测试按钮**（对勾图标）验证选择器是否能正确命中元素，并显示元素位置和尺寸信息 ### 文件命名与保存位置 - 文件名：`{SKU}.png`（特殊字符自动替换为 `_`） - 保存位置：导出目录下的 `screenshots/` 子文件夹 - 采集开始时自动预建该文件夹 ### 导入/导出 截图设置随规则集一起保存，支持导入和导出 JSON 规则文件。 --- **English** Screenshot settings are located **below the field list** in the Detail Page Rules tab, configured per rule set independently. ### Enable Screenshot When **Enable Screenshot** is checked, a screenshot is taken automatically after each detail page is scraped. ### Screenshot Modes | Mode | Description | | -------------------------------------------- | --------------------------------------------------------------------------------- | | Visible Area (Default) | Captures the current browser viewport | | Full Page | Captures the entire page including scrolled content, via Chrome DevTools Protocol | | Scroll to element, then capture visible area | Scrolls to the target element, then captures the viewport | | Capture only the specific element | Precisely crops to the element's boundaries | > "Full Page" and "Capture only the specific element" modes require the `debugger` permission, which is released immediately after each screenshot. ### Element Selector - Enter a CSS selector for the target element - Click the **Picker button** (crosshair icon) to pick an element directly from the page - Click the **Test button** (checkmark icon) to verify the selector matches correctly, showing the element's position and dimensions ### File Naming & Save Location - Filename: `{SKU}.png` (special characters replaced with `_`) - Saved to: `screenshots/` subfolder inside the export directory - The folder is automatically pre-created when scraping begins ### Import / Export Screenshot settings are saved as part of the rule set and are included in JSON rule set import/export. --- ## 导出结果 / Export Results **中文** 采集完成后自动导出： - **Excel 文件**（`.xlsx`，含时间戳）：含表头样式、边框、自动筛选、冻结首行 - **图片文件**：按规则自动下载到对应目录 - **截图文件**：保存到 `screenshots/` 目录（若启用） ### 导出目录结构示例 ``` 导出目录/ ├── 商品数据_2026-04-22T13-30-00.xlsx ├── images/ │ ├── ABC001/ │ │ ├── main/ │ │ │ ├── 01_ABC001.jpg │ │ │ └── 02_ABC001.jpg │ │ └── description/ │ │ └── ABC001_01.jpg │ └── XYZ002/ │ └── ... └── screenshots/ # 仅启用截图时存在 ├── ABC001.png └── XYZ002.png ``` **English** After scraping, the following are exported automatically: - **Excel file** (`.xlsx` with timestamp): styled headers, borders, auto-filter, frozen first row - **Image files**: downloaded to the configured directories - **Screenshots**: saved to `screenshots/` directory (if enabled) ### Export Directory Structure Example ``` export-dir/ ├── ProductData_2026-04-22T13-30-00.xlsx ├── images/ │ ├── ABC001/ │ │ ├── main/ │ │ │ ├── 01_ABC001.jpg │ │ │ └── 02_ABC001.jpg │ │ └── description/ │ │ └── ABC001_01.jpg │ └── XYZ002/ │ └── ... └── screenshots/ # Only present when screenshot is enabled ├── ABC001.png └── XYZ002.png ``` --- ## 规则管理 / Rule Management **中文** | 操作 | 说明 | | ----------------- | -------------------------------------------- | | 导出规则集 | 将当前规则集（含截图设置）保存为 JSON 文件 | | 导入规则集 | 从 JSON 文件加载规则集，可选择立即应用到当前 | | 备份自定义规则 | 导出所有自定义规则集为一个 JSON 备份文件 | | 全局配置导出/导入 | 包含所有规则集、设置项、列表配置的完整备份 | **English** | Action | Description | | --------------------------- | --------------------------------------------------------------------- | | Export Rule Set | Save current rule set (including screenshot settings) as a JSON file | | Import Rule Set | Load a rule set from a JSON file; optionally apply immediately | | Backup Custom Rules | Export all custom rule sets as a single JSON backup | | Global Config Export/Import | Full backup including all rule sets, settings, and list configuration | --- ## 注意事项 / Notes **中文** - 抓取间隔建议 ≥ 5 秒，避免对目标网站造成压力 - 列表模式使用前建议先测试选择器和字段命中情况 - 部分站点需要登录后才能抓取完整数据 - 列表翻页最多 200 页，超限自动停止 - 使用全页面截图时，页面会短暂被 Debugger 附加，部分有反爬机制的站点可能会检测到 - 截图功能要求标签页在采集时保持激活状态（插件会自动切换） **English** - Set scrape interval ≥ 5 seconds to avoid overloading the target site - Always test selectors and field matching before starting a full list scrape - Some sites require you to be logged in to scrape full product data - List pagination is capped at 200 pages; scraping stops automatically after that - Full-page screenshot mode briefly attaches a Debugger to the tab; some anti-bot systems may detect this - Screenshot capture requires the tab to be active; the extension switches to it automatically
