1、alert警告框

以百度搜索设置为例，在进行搜索设置后点击“保存设置”按钮，弹出alert对话框，如下图所示：

实现代码：

from selenium import webdriver

import time as t

from selenium.webdriver.support.select import Select

from selenium.webdriver.common.keys import Keys

from selenium.webdriver.common.action_chains import ActionChains

from selenium.webdriver.support.wait import WebDriverWait

from selenium.webdriver.support import expected_conditions as ec

from selenium.webdriver.common.by import By

driver = webdriver.Chrome()

driver.maximize_window()

driver.get("http://www.baidu.com")

t.sleep(3)

driver.find_element_by_id("kw").send_keys("selenium")

driver.find_element_by_id("su").send_keys(Keys.ENTER)

# 显式等待，待元素定位

WebDriverWait(driver,10).until(ec.presence_of_element_located((By.ID,"kw")))

# 鼠标悬停

mouse = driver.find_element_by_name("tj_settingicon")

ActionChains(driver).move_to_element(mouse).perform()

driver.find_element_by_link_text('搜索设置').click()

# # 隐式等待

# driver.implicitly_wait(10)

t.sleep(5)

# 定位下拉框

select = driver.find_element_by_name("NR")

# # 以索引的方式定位

# Select(select).select_by_index(2)

# print("下拉框选择的最新条数是：",select.get_attribute('value'))

# 以value定位

# Select(select).select_by_value("10")

# print("下拉框选择的最新条数是：",select.get_attribute('value'))

# 以文本定位

Select(select).select_by_visible_text("每页显示10条")

print("下拉框选择的最新条数是：",select.get_attribute('value'))

t.sleep(3)

driver.find_element_by_xpath('//*[@id="se-setting-5"]/label[1]').click()

t.sleep(4)

# 判断是否选中is_selected()

s = driver.find_element_by_xpath('//*[@id="se-setting-5"]/label[1]').is_selected()

if s == False:

driver.find_element_by_xpath('//*[@id="se-setting-5"]/label[1]').click()

print(s)

else:

print(True)

driver.find_element_by_css_selector("#gxszButton > a.prefpanelgo").click()

# alert弹框

print("alert弹出框的文本信息为：{0}".format(driver.switch_to.alert.text)) # 获取弹出框的文本信息

driver.switch_to.alert.accept()

driver.quit()

ps：driver.switch_to.alert后不加()，否则会出现TypeError

accept()表示确认

dismiss()表示取消

2、confirm确认框

显示：

实现代码：

from selenium import webdriver

import time

url = 'file:///C:/Users/yl8/Desktop/链接.html'

driver = webdriver.Chrome()

driver.get(url)

time.sleep(4)

# confirm操作

driver.find_element_by_id("confirm").click()

time.sleep(2)

t = driver.switch_to.alert

print(t.text)

t.dismiss()

3、prompt对话框

类型：

实现测试代码：

from selenium import webdriver

import time

url = 'file:///C:/Users/yl8/Desktop/链接.html'

driver = webdriver.Chrome()

driver.get(url)

time.sleep(4)

# prompt操作

driver.find_element_by_id("prompt").click()

time.sleep(2)

t = driver.switch_to.alert

print(t.text)

t.send_keys("hello selenium")

t.accept()
