咱们在运用selenium进行自动化测试的过程中，遇到输入框时，咱们能够运用send_keys（）输入内容，也能够运用键盘事情向输入框内输入内容，仅仅运用键盘事情时需求导入Keys，作为一款强壮的工具，selenium有的功用，playwright也有，playwright相同能够运用键盘输入内容，本篇文章就来为大家介绍一下playwright的键盘事情。

键盘操作
playwright的Keyboard 方法是用于键盘操作的函数，供给了一个用于办理虚拟键盘的 API。高级 api 是keyboard.type()，它接受原始字符并在您的页面上生成恰当的keydown、keypress/input和keyup事情。 为了更好地控制，您能够运用keyboard.down()、keyboard.up()和keyboard.insert_text()手动触发事情，就好像它们是从真实键盘生成的一样。
- 选择和删去文本
from playwright.sync_api import sync_playwright
def key_option():
with sync_playwright() as playwright:
browser = playwright.chromium.launch(headless=False)
context = browser.new_context()
page = context.new_page()
page.goto("https://www.baidu.com/")
page.locator("#kw").click()
page.keyboard.type("playwright")
page.keyboard.down("Shift")
for i in range(6):
page.keyboard.press("ArrowLeft")
page.keyboard.up("Shift")
page.keyboard.press("Backspace")
page.pause()
context.close()
browser.close()
key_option()
运转脚本之后，playwright的文本中后面6个字母被删去，成果如下图所示：
- 输入大写字母
from playwright.sync_api import sync_playwright
def key_option():
with sync_playwright() as playwright:
browser = playwright.chromium.launch(headless=False)
context = browser.new_context()
page = context.new_page()
page.goto("https://www.baidu.com/")
page.locator("#kw").click()
page.keyboard.press("Shift+KeyA")
page.pause()
context.close()
browser.close()
key_option()
运转脚本，界面如下图所示：
注：运用Shift+A一样能够按出大写字母A
- 全选操作
from playwright.sync_api import sync_playwright
def key_option():
with sync_playwright() as playwright:
browser = playwright.chromium.launch(headless=False)
context = browser.new_context()
page = context.new_page()
page.goto("https://www.baidu.com/")
page.locator("#kw").click()
page.keyboard.type("playwright")
page.keyboard.press("Control+A")
page.pause()
context.close()
browser.close()
key_option()
运转脚本之后，界面如下所示：
注：Mac体系的键盘操作为‘Meta+A’
Down事情
调度keydown事情
key能够指定预期的keyboardEvent.key值或单个字符来为其生成文本。能够在此处key找到这些值的超集。键的比如是：
F1- F12, Digit0- Digit9, KeyA- KeyZ, Backquote, Minus, Equal, Backslash, Backspace, Tab, Delete, Escape, ArrowDown, End, Enter, Home, , , Insert,等_PageDownPageUpArrowRightArrowUp
还支撑以下修正快捷方式：Shift, Control, Alt, Meta, ShiftLeft.
按住将键入对应于大写字母Shift的文本。key
假如key是单个字符，则区别大小写，因此值a和A将生成各自不同的文本。
假如key是润饰键 、Shift、Meta、Control或Alt，则后续按键将在该润饰键激活的情况下发送。要开释润饰键，请运用keyboard.up()。
按下一次键后，对keyboard.down()的后续调用会将repeat设置为 true。要开释键，请运用keyboard.up()。
语法如下：
keyboard.down(key)
insert_text 刺进文本
语法如下：
page.keyboard.insert_text("xxxx")
注：该操作只调度input事情，不发出keydown,keyup或keypress事情。
press 长按
key能够指定预期的keyboardEvent.key值或单个字符来为其生成文本。能够在此处key找到这些值的超集。键的比如是：F1- F12, Digit0- Digit9, KeyA- KeyZ, Backquote, Minus, Equal, Backslash, Backspace, Tab, Delete, Escape, ArrowDown, End, Enter,Insert等
示例代码：
from playwright.sync_api import sync_playwright
def key_option():
with sync_playwright() as playwright:
browser = playwright.chromium.launch(headless=False)
context = browser.new_context()
page = context.new_page()
page.goto("https://keycode.info")
page.keyboard.press("a")
page.screenshot(path="a.png")
page.keyboard.press("ArrowLeft")
page.screenshot(path="arrow_left.png")
page.keyboard.press("Shift+O")
page.screenshot(path="o.png")
page.pause()
context.close()
browser.close()
key_option()
运转脚本，截取的图片如下：
Type 操作
为文本中的每个字符发送keydown、keypress/input和事情。
示例如下：
from playwright.sync_api import sync_playwright
def key_option():
with sync_playwright() as playwright:
browser = playwright.chromium.launch(headless=False)
context = browser.new_context()
page = context.new_page()
page.goto("https://www.baidu.com/")
page.locator("#kw").click()
page.keyboard.type("拜仁")
page.keyboard.type("慕尼黑", delay=100)
page.pause()
context.close()
browser.close()
key_option()
运转脚本，成果如下图：
up 方法
调度一个keyup事情，语法示例如下：
keyboard.up(key)
总结
本文主要介绍了playwright对键盘操作的方法，与selenium类似，playwright相同支撑对键盘的操作，同时，playwright的键盘操作比之selenium愈加方便快捷。
