页面
每个 浏览器上下文 可以包含多个页面。一个 页面 代表浏览器上下文中的单个标签页或弹出窗口。它应该用于导航到 URL 并与页面内容进行交互。
- 同步
- 异步
page = context.new_page()
# Navigate explicitly, similar to entering a URL in the browser.
page.goto('http://example.com')
# Fill an input.
page.locator('#search').fill('query')
# Navigate implicitly by clicking a link.
page.locator('#submit').click()
# Expect a new url.
print(page.url)
page = await context.new_page()
# Navigate explicitly, similar to entering a URL in the browser.
await page.goto('http://example.com')
# Fill an input.
await page.locator('#search').fill('query')
# Navigate implicitly by clicking a link.
await page.locator('#submit').click()
# Expect a new url.
print(page.url)
多个页面
每个浏览器上下文可以承载多个页面(标签页)。
- 每个页面都像一个聚焦的、活跃的页面。不需要将页面置于最前。
- 上下文中的页面遵守上下文级别的模拟,例如视窗大小、自定义网络路由或浏览器区域设置。
- 同步
- 异步
# create two pages
page_one = context.new_page()
page_two = context.new_page()
# get pages of a browser context
all_pages = context.pages
# create two pages
page_one = await context.new_page()
page_two = await context.new_page()
# get pages of a browser context
all_pages = context.pages
处理新页面
浏览器上下文上的 page
事件可用于获取在上下文中创建的新页面。这可用于处理由 target="_blank"
链接打开的新页面。
- 同步
- 异步
# Get page after a specific action (e.g. clicking a link)
with context.expect_page() as new_page_info:
page.get_by_text("open new tab").click() # Opens a new tab
new_page = new_page_info.value
# Interact with the new page normally
new_page.get_by_role("button").click()
print(new_page.title())
# Get page after a specific action (e.g. clicking a link)
async with context.expect_page() as new_page_info:
await page.get_by_text("open new tab").click() # Opens a new tab
new_page = await new_page_info.value
# Interact with the new page normally
await new_page.get_by_role("button").click()
print(await new_page.title())
如果触发新页面的操作未知,可以使用以下模式。
- 同步
- 异步
# Get all new pages (including popups) in the context
def handle_page(page):
page.wait_for_load_state()
print(page.title())
context.on("page", handle_page)
# Get all new pages (including popups) in the context
async def handle_page(page):
await page.wait_for_load_state()
print(await page.title())
context.on("page", handle_page)
处理弹出窗口
如果页面打开弹出窗口(例如,由 target="_blank"
链接打开的页面),可以通过监听页面上的 popup
事件来获取对该弹出窗口的引用。
除了 browserContext.on('page')
事件之外,还会发出此事件,但仅针对与该页面相关的弹出窗口。
- 同步
- 异步
# Get popup after a specific action (e.g., click)
with page.expect_popup() as popup_info:
page.get_by_text("open the popup").click()
popup = popup_info.value
# Interact with the popup normally
popup.get_by_role("button").click()
print(popup.title())
# Get popup after a specific action (e.g., click)
async with page.expect_popup() as popup_info:
await page.get_by_text("open the popup").click()
popup = await popup_info.value
# Interact with the popup normally
await popup.get_by_role("button").click()
print(await popup.title())
如果触发弹出窗口的操作未知,可以使用以下模式。
- 同步
- 异步
# Get all popups when they open
def handle_popup(popup):
popup.wait_for_load_state()
print(popup.title())
page.on("popup", handle_popup)
# Get all popups when they open
async def handle_popup(popup):
await popup.wait_for_load_state()
print(await popup.title())
page.on("popup", handle_popup)
