单击iframe - pyppeteer中的按钮

import asyncio
from pyppeteer import launch

async def click_button_in_iframe():
    browser = await launch()
    page = await browser.newPage()
    await page.goto('https://example.com')  # 进入包含iframe的页面

    # 获取iframe元素
    iframe_element = await page.waitForSelector('iframe')
    frame = await iframe_element.contentFrame()

    # 切换到iframe中
    await page.bringToFront()
    await page.waitFor(1000)  # 等待一段时间确保切换完成

    # 定位到按钮元素并点击
    button_element = await frame.waitForSelector('button')
    await button_element.click()

    await browser.close()

# 运行示例代码
asyncio.get_event_loop().run_until_complete(click_button_in_iframe())
