Dialog

Dialog 对象会在页面触发 page.on("dialog") 事件时生成。 示例：

Sync

from playwright.sync_api import sync_playwright

def handle_dialog(dialog):
    print(dialog.message)
    dialog.dismiss()

def run(playwright):
    browser = playwright.chromium.launch()
    page = browser.new_page()
    page.on("dialog", handle_dialog)
    page.evaluate("alert('1')")
    browser.close()

with sync_playwright() as playwright:
    run(playwright)

Async

import asyncio
from playwright.async_api import async_playwright

async def handle_dialog(dialog):
    print(dialog.message)
    await dialog.dismiss()

async def run(playwright):
    browser = await playwright.chromium.launch()
    page = await browser.new_page()
    page.on("dialog", handle_dialog)
    await page.evaluate("alert('1')")
    await browser.close()

async def main():
    async with async_playwright() as playwright:
        await run(playwright)

asyncio.run(main())

note

如未监听 page.on("dialog")，对话框会自动关闭。一旦注册监听器，就必须调用 dialog.accept(**kwargs) 或 dialog.dismiss()。否则页面会一直等待对话框，导致点击等操作无法完成。

• dialog.accept(**kwargs)
• dialog.default_value
• dialog.dismiss()
• dialog.message
• dialog.type

dialog.accept(**kwargs)

Added in: v1.8

• prompt_text <str> 向 prompt 类型对话框输入的文本，仅当 type 为 prompt 时生效，可选。#
• 返回值: <NoneType>#

当对话框被接受后返回。

dialog.default_value

Added in: v1.8

• 返回值: <str>#

若对话框为 prompt，则返回默认提示内容，否则返回空字符串。

dialog.dismiss()

Added in: v1.8

• 返回值: <NoneType>#

当对话框被关闭后返回。

dialog.message

Added in: v1.8

• 返回值: <str>#

返回对话框中显示的文本。

dialog.type

Added in: v1.8

• 返回值: <str>#

对话框类型，可能为 alert、beforeunload、confirm 或 prompt。
