javascript 弹出框处理

---

js弹出框的方法使用：

先使用switch_to.alert切换到浏览器弹出框

再使用alert类的操作方法：

• dismiss()：取消
• accept()：确定
• text()：获取弹框中的文本信息
• send_keys()：往弹框中输入文本信息

---

js之：alerts弹框：

import time
from selenium import webdriver
from selenium.webdriver.support.wait import webdriverwait
from selenium.webdriver.support import expected_conditions as ec
from selenium.webdriver.common.desired_capabilities import desiredcapabilities


desired_capabilities = desiredcapabilities.chrome
desired_capabilities['pageloadstrategy'] = 'normal'
driver = webdriver.chrome()
start_time = time.time()
driver.get('https://www.selenium.dev/documentation/en/webdriver/js_alerts_prompts_and_confirmations/')
end_time = time.time() - start_time
print(end_time)
driver.find_element_by_xpath("//a[contains(text(),'see an example alert')]").click()
webdriverwait(driver, 10).until(ec.alert_is_present())
alert = driver.switch_to.alert
text_info = alert.text
print(text_info)
alert.accept()
time.sleep(10)
driver.quit()

控制台显示了js弹框中的文本信息：

f:virtualenvironmentvenvscriptspython.exe f:/git/auomationtest/auomationtestproject/webtestauomation/element_localization.py

js之：confirm弹框：

import time
from selenium import webdriver
from selenium.webdriver.support.wait import webdriverwait
from selenium.webdriver.support import expected_conditions as ec
from selenium.webdriver.common.desired_capabilities import desiredcapabilities

desired_capabilities = desiredcapabilities.chrome
desired_capabilities['pageloadstrategy'] = 'normal'
driver = webdriver.chrome()
start_time = time.time()
driver.get('https://www.selenium.dev/documentation/en/webdriver/js_alerts_prompts_and_confirmations/')
end_time = time.time() - start_time
print(end_time)
driver.find_element_by_css_selector(
    "section:nth-child(2) div.padding.highlightable:nth-child(2) div:nth-child(3) p:nth-child(8) > a.highlight").click()
webdriverwait(driver, 10).until(ec.alert_is_present())
alert = driver.switch_to.alert
text_info = alert.text
print(text_info)
alert.dismiss()
time.sleep(10)
driver.quit()

控制台显示了js弹框中的文本信息：

f:virtualenvironmentvenvscriptspython.exe f:/git/auomationtest/auomationtestproject/webtestauomation/element_localization.py

js之：prompt弹框：

import time
from selenium import webdriver
from selenium.webdriver.support.wait import webdriverwait
from selenium.webdriver.support import expected_conditions as ec
from selenium.webdriver.common.desired_capabilities import desiredcapabilities

desired_capabilities = desiredcapabilities.chrome
desired_capabilities['pageloadstrategy'] = 'normal'
driver = webdriver.chrome()
start_time = time.time()
driver.get('https://www.w3school.com.cn/tiy/t.asp?f=js_prompt')
driver.find_element_by_css_selector(
    "body:nth-child(2) div:nth-child(2) ul:nth-child(1) li:nth-child(4) > a:nth-child(1)").click()
iframe = driver.find_element_by_xpath("//iframe[@id='iframeresult']")
driver.switch_to.frame(iframe)
driver.find_element_by_css_selector("body:nth-child(2) > button:nth-child(2)").click()
webdriverwait(driver, 10).until(ec.alert_is_present())
alert = driver.switch_to.alert
alert.send_keys("自动化测试")
time.sleep(2)
alert.accept()

注意：敲黑板并划重点：

alert.send_key()输入的数据，是不会把弹框中的默认参数替换掉的

所以百度了一个能看到alert弹框返回值的栗子：

首先我在send_key()中输入的是 ” 自动化测试 ” 然后点击 ” 确定 ” ，页面显示的就是我输入的返回值：
