page.locator("css=button")

# 直接填充page.locator("#username").fill("输入内容")# 逐字输入page.locator('#area').press_sequentially("输入内容")

点击按钮

# 左键点击,force为强制点击page.locator("#submit").click(force=True)# 右击page.locator("#submit").click(button="right")# 双击page.locator("#submit").dbclick()# shift+左键点击page.locator("#submit").click(modifiers=["Shift"])# 鼠标悬浮page.locator("#submit").hover()# 点击所选中元素的指定位置page.locator("#submit").click(position={ "x": 0, "y": 0})

单选/复选框

# 点击触发选中或者取消选中page.locator("#sex").check()# 校验是否被选中expect(page.locator('#sex')).to_be_checked()

下拉框选项

# 单选（匹配值/标签）page.locator("#sex").select_option('男')# 单选（仅匹配标签）page.locator("#sex").select_option(label='男')# 多选page.locator("#sex").select_option(['red', 'green', 'blue'])

常用的断言列表

断言列表

会话状态存储

“

当前目录下创建一个.auth 目录用于存储

# 保存当前状态storage = context.storage_state(path="state.json")# 使用之前的状态context = browser.new_context(storage_state="state.json")

对话框处理

“

必须监听dialog 事件

# 点击确认page.on("dialog", lambda dialog: dialog.accept())# 点击关闭page.on("dialog", lambda dialog: dialog.dismiss())# 自定义处理逻辑defhandle_dialog(dialog):  # 具体逻辑      dialog.dismiss()page.on("dialog", lambda: handle_dialog)

设备模拟

“

playwright.devices 指定设备,设备列表

from playwright.sync_api import sync_playwright, Playwright  defrun(playwright: Playwright):      iphone_13 = playwright.devices['iPhone 13']      browser = playwright.webkit.launch(headless=False)      context = browser.new_context(      **iphone_13,      )with sync_playwright() as playwright:      run(playwright)

执行JS

# 直接执行page.evaluate('object => object.foo', { 'foo': 'bar' })button = page.evaluate_handle('window.button')  page.evaluate('button => button.textContent', button)

事件监听

# 监听请求page.on("request", lambda request: print(">>", request.method, request.url))# 监听响应  page.on("response", lambda response: print("<<", response.status, response.url))

截图

全屏截图

page.screenshot(path="screenshot.png", full_page=True)

单个元素截图

page.locator(".header").screenshot(path="screenshot.png")
