Selenium与chromediver的使用学习
demo1：
# webdriver.Chrome使用
# 获取driver.page_source
import time
from selenium import webdriver
# 驱动路径
driver_path = r"E:pythonfilechromedriverchromedriver.exe"
# 创建驱动
driver = webdriver.Chrome(executable_path=driver_path)
driver.get('https://www.baidu.com/')
# 打印网页源代码
print(driver.page_source)
time.sleep(5)
# 关闭当前页面
driver.close()
# 关闭整个网页
driver.quit()
demo2：
1 # 定位元素
2
3 from selenium import webdriver
4 from selenium.webdriver.common.by import By
5
6 # 驱动路径
7 driver_path = r"E:pythonfilechromedriverchromedriver.exe"
8
9 # 创建驱动
10 driver = webdriver.Chrome(executable_path=driver_path)
11
12 driver.get('https://www.baidu.com/')
13
14 # 通过id获取
15 # inputTag = driver.find_element_by_id('kw')
16 inputTag = driver.find_element(By.ID, 'kw') # 其他的原理一样
17
18 # 通过name获取
19 # inputTag = driver.find_element_by_name('wd')
20
21 # 通过class属性获取
22 # inputTag = driver.find_element_by_class_name('s_ipt')
23
24 # xpath语法获取
25 # inputTag = driver.find_element_by_xpath("//input[@id='kw']")
26
27 # CSS选择器
28 # inputTag = driver.find_element_by_css_selector('.quickdelete-wrap > input')
29
30 # 框框里输入java
31 inputTag.send_keys('java')
demo3：
1 # 操作表单元素
2
3 from selenium import webdriver
4 import time
5
6 # 驱动路径
7 driver_path = r"E:pythonfilechromedriverchromedriver.exe"
8 # 创建驱动
9 driver = webdriver.Chrome(executable_path=driver_path)
10 driver.get('https://www.baidu.com/')
11
12 # 1.操作输入框
13 # inputTag = driver.find_element_by_id('kw')
14 # 输入
15 # inputTag.send_keys('java')
16 # time.sleep(5)
17 # 清除
18 # inputTag.clear()
19
20 # 2.check的话 同样获取
21 # click()就点亮 在click就灭了
22
23 # 3.Select的话 比较复杂
24 # selectBtn =Select(driver.find_element_by_id('kw'))
25 # selectBtn.select_by_index(1)
26 # selectBin.select_by_values(url)
27 # selectBin.select_by_visible_text("名称")
28 # 取消选中
29 # selectTag.deselect_all()
30
31 # 4.按钮的点击事件
32 inputTag = driver.find_element_by_id('kw')
33 inputTag.send_keys('java')
34 submitTag = driver.find_element_by_id('su')
35 submitTag.click()
demo4：
# 网页中input在 ifame如何操作
from selenium import webdriver
# 驱动路径
driver_path = r"E:pythonfilechromedriverchromedriver.exe"
# 创建驱动
driver = webdriver.Chrome(executable_path=driver_path)
driver.get("https://www.douban.com/")
# 找到iframe 因为我用的这个iframe是没有id和name的 因此需先xpath获取然后操作
iframe = driver.find_element_by_xpath("//div[@class='login']//iframe")
# 如果iframe 有id的话可直接替换
# driver.switch_to.frame('id属性值')
driver.switch_to.frame(iframe)
rememberBtn = driver.find_element_by_name('phone')
rememberBtn.send_keys('555')
# 释放回到当前主页面
driver.switch_to_default.content()
