框架
简介
一个Page可以附加一个或多个Frame对象。每个页面都有一个主框架，页面级别的交互（如click）默认在主框架中操作。
A page can have additional frames attached with the iframe HTML tag. These frames can be accessed for interactions inside the frame.
- Sync
- 异步
# Locate element inside frame
# Get frame using any other selector
username = page.frame_locator('.frame-class').get_by_label('User Name')
username.fill('John')
# Locate element inside frame
username = await page.frame_locator('.frame-class').get_by_label('User Name')
await username.fill('John')
Frame对象
可以使用page.frame() API访问框架对象：
- Sync
- 异步
# Get frame using the frame's name attribute
frame = page.frame('frame-login')
# Get frame using frame's URL
frame = page.frame(url=r'.*domain.*')
# Interact with the frame
frame.fill('#username-input', 'John')
# Get frame using the frame's name attribute
frame = page.frame('frame-login')
# Get frame using frame's URL
frame = page.frame(url=r'.*domain.*')
# Interact with the frame
await frame.fill('#username-input', 'John')
