Implementation Reference
- src/playwright_server/server.py:281-322 (handler)The GetTextContentToolHandler class that executes the tool logic: checks for active session, evaluates JavaScript to extract unique text from visible elements with <=3 children and their values, returns the list of texts.class GetTextContentToolHandler(ToolHandler): async def handle(self, name: str, arguments: dict | None) -> list[types.TextContent | types.ImageContent | types.EmbeddedResource]: if not self._sessions: return [types.TextContent(type="text", text="No active session. Please create a new session first.")] session_id = list(self._sessions.keys())[-1] page = self._sessions[session_id]["page"] # text_contents = await page.locator('body').all_inner_texts() async def get_unique_texts_js(page): unique_texts = await page.evaluate('''() => { var elements = Array.from(document.querySelectorAll('*')); // 先选择所有元素，再进行过滤 var uniqueTexts = new Set(); for (var element of elements) { if (element.offsetWidth > 0 || element.offsetHeight > 0) { // 判断是否可见 var childrenCount = element.querySelectorAll('*').length; if (childrenCount <= 3) { var innerText = element.innerText ? element.innerText.trim() : ''; if (innerText && innerText.length <= 1000) { uniqueTexts.add(innerText); } var value = element.getAttribute('value'); if (value) { uniqueTexts.add(value); } } } } //console.log( Array.from(uniqueTexts)); return Array.from(uniqueTexts); } ''') return unique_texts # 使用示例 text_contents = await get_unique_texts_js(page) return [types.TextContent(type="text", text=f"Text content of all elements: {text_contents}")]
