+
+## Project Overview
+
+This is a Python automation project using Playwright to interact with a Chinese ERP system (YonBIP/用友). The scripts automate login, navigation, form filling, and data submission workflows in a nested iframe environment.
+
+## Environment Setup
+
+```bash
+# Activate the virtual environment (Windows)
+.venv\Scripts\activate
+
+# Install dependencies
+pip install playwright
+
+# Install Playwright browsers
+playwright install chromium
+```
+
+## Running Scripts
+
+```bash
+# Run the main test script
+python test_playwright.py
+
+# Run the record script
+python record.py
+```
+
+## Key Dependencies
+
+- **playwright==1.57.0**: Browser automation framework
+- Uses synchronous API (`playwright.sync_api`)
+
+## Architecture
+
+### Nested Iframe Structure
+
+The target application uses deeply nested iframes that require careful handling:
+
+```
+page (browser context)
+  └── #forwardFrame (main iframe)
+      └── #mainiframe (inner iframe, contains actual application UI)
+```
+
+**Critical Pattern**: When accessing nested iframes, always wait for the inner iframe to be visible before extracting its content frame:
+
+```python
+outer_frame = page.locator("#forwardFrame").content_frame
+inner_frame_locator = outer_frame.locator("#mainiframe")
+inner_frame_locator.wait_for(state="visible", timeout=15000)
+inner_frame = inner_frame_locator.content_frame
+```
+
+### Loading State Management
+
+The application uses loading overlays ("加载中") that must be detected and waited for:
+
+```python
+# Detect and wait for loading to complete
+loading_locator = frame.locator("div").filter(has_text="加载中").nth(1)
+try:
+    loading_locator.wait_for(state="visible", timeout=3000)
+    loading_locator.wait_for(state="hidden", timeout=0)  # Infinite wait
+except TimeoutError:
+    # Loading completed quickly or never appeared
+    pass
+```
+
+### Page Navigation Pattern
+
+New windows/popups are handled using `expect_popup()`:
+
+```python
+with page.expect_popup() as popup_info:
+    some_button.click()
+new_page = popup_info.value
+```
+
+## Common Utilities
+
+### `get_input_by_label(frame, label_text)`
+
+Locates input fields by their associated label text. Searches upward through parent containers to find the input:
+
+```python
+input_box = get_input_by_label(frame, "生产部门")
+if input_box:
+    current_value = input_box.input_value()
+    input_box.fill("new value")
+```
+
+### `click_button_until_disappear(frame, button_name, max_attempts, max_duration)`
+
+Continuously clicks a button until it disappears from the DOM. Includes logic to auto-fill missing data before each click.
+
+## Development Notes
+
+- **Browser launch**: `chromium.launch(headless=False)` for debugging
+- **HTTPS errors**: Ignored with `ignore_https_errors=True` due to self-signed certificates on target system
+- **Locators**: Uses role-based locators (`get_by_role()`) where possible, falling back to CSS selectors and text filtering
+- **Text matching**: Uses regular expressions for matching text with patterns like `re.compile(r"^生产部门$")`
+- **Date format**: "YYYY-MM-DD" (e.g., "2025-12-28")
+- **Language**: Application is in Chinese; comments and print statements use Chinese for clarity
+- **Debugging**: Uses `pdb.set_trace()` for interactive debugging sessions
+
+## Target Application Details
+
+- **URL**: `https://68.11.34.30:8082/` (internal network)
+- **System**: YonBIP (用友) ERP system
+- **Login**: Requires username and password; may show "force login" confirmation dialog
+- **Key workflows**:
+  - "补货安排" (Replenishment Arrangement)
+  - "生产订单" (Production Orders)
+  - Batch data submission with "保存提交" (Save & Submit) button
