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.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：

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：
