你可以使用 Playwright 的 `fill` 方法来清空 `textarea` 元素的内容,例如:
```python
from playwright.sync_api import Playwright, sync_playwright
with sync_playwright() as p:
browser = p.chromium.launch()
page = browser.new_page()
page.goto("https://example.com")
# 获取 textarea 元素
textarea = page.locator("#my-textarea")
# 清空 textarea 内容
textarea.fill("")
```
在上面的代码中,我们首先使用 `page.locator` 方法获取 `id` 为 `my-textarea` 的 `textarea` 元素,然后使用 `fill` 方法将其内容设置为空字符串,即可实现清空 `textarea` 内容的功能。

你可以使用以下代码来清空一个textarea元素的内容:
```js
const { firefox } = require('playwright');
(async () => {
const browser = await firefox.launch();
const page = await browser.newPage();
await page.goto('https://www.example.com');
// 获取textarea元素
const textarea = await page.$('textarea');
