页面
¥Pages
每个 BrowserContext 可以有多个页面。Page 指的是浏览器上下文中的单个选项卡或弹出窗口。它应用于导航到 URL 并与页面内容交互。
¥Each BrowserContext can have multiple pages. A Page refers to a single tab or a popup window within a browser context. It should be used to navigate to URLs and interact with the page content.
- Sync
- Async
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)
多页
¥Multiple pages
每个浏览器上下文可以托管多个页面(选项卡)。
¥Each browser context can host multiple pages (tabs).
-
每个页面的行为就像一个集中的活动页面。不需要将页面置于前面。
¥Each page behaves like a focused, active page. Bringing the page to front is not required.
-
上下文内的页面遵循上下文级模拟,例如视口大小、自定义网络路由或浏览器区域设置。
¥Pages inside a context respect context-level emulation, like viewport sizes, custom network routes or browser locale.
- Sync
- Async
# 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
¥Handling new pages
浏览器上下文中的 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 target="_blank"
链接打开的新页面。
¥The page
event on browser contexts can be used to get new pages that are created in the context. This can be used to handle new pages opened by target="_blank"
links.
- Sync
- Async
# 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,则可以使用以下模式。
¥If the action that triggers the new page is unknown, the following pattern can be used.
- Sync
- Async
# 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
¥Handling popups
如果页面打开了一个弹出窗口(例如通过 target="_blank"
链接打开的页面),你可以通过监听页面上的 popup
事件来获取对其的引用。
¥If the page opens a pop-up (e.g. pages opened by target="_blank"
links), you can get a reference to it by listening to the popup
event on the page.
除了 browserContext.on('page')
事件之外,还会触发此事件,但仅针对与此页面相关的弹出窗口。
¥This event is emitted in addition to the browserContext.on('page')
event, but only for popups relevant to this page.
- Sync
- Async
# 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,则可以使用以下模式。
¥If the action that triggers the popup is unknown, the following pattern can be used.
- Sync
- Async
# 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)
