web自动化8-selenium简单操作方法

1.    控制窗口大小

form selenium import webdriver

driver = webdriver.Chrome()

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

print("设置浏览器宽480，高800显示")

driver.set_window_size(480,800)

driver.quit()

 

2.    控制浏览器前进，后退

form selenium import webdriver

frist_url = "http://www.baidu.com"

print("frist is %s" %(frist_url))

driver.get(frist_url)

second_url = "http://www.sina.com"

print("second is %s" %(second_url))

driver.get(second_url)

print("back to frist_url %s" %(frist_url))

driver.back()

print("forward to second_url %s" %(second_url))

driver.forward()

driver.quit()

 

3.    浏览器刷新

driver.refresh()

 

4.    简单元素的操作（sina邮箱登录）

form selenium import webdrver

driver = webdriver.Chrome()

driver.get("http://mail.sina.com")

driver.find_element_by_id("freename").clear()
driver.find_element_by_id("freename").send_keys("zhang@sina.com")
time.sleep(2)
driver.find_element_by_id("freepassword").clear()
driver.find_element_by_id("freepassword").send_keys("")
time.sleep(2)
driver.find_element_by_class_name("loginBtn").click()
time.sleep(4)
driver.quit()

5.    提交表单

.click()可以代替.submit()

 

6. 获得输入框尺寸

size = driver.find_element_by_id("kw").size

print(size)

 

7.    获得元素的文字

text = driver.find_element_by_id("cp").text

print(text)

 

8.    返回元素的属性值

attribute = driver.find_element_by_id("kw").get_attribute("type")

print(attribute)

 

9.    返回元素是否可见

result = driver.find.element_by_id("kw").displayed()

print(result)

 

10.    输入文字和清空文字

browser.find_element_by_id(“kw”).send_keys(“1234”)    在kw元素上输入‘1234’

browser.find_element_by_id(“kw”).clear()                  清空kw元素输入的信息

 

11.    截图

from selenium import webdriver
from time import sleep
driver = webdriver.Chrome()
driver.get("http://www.baidu.com/")
driver.find_element_by_id("kw").send_keys("selenium")
driver.find_element_by_id("su").click()
sleep(2)
driver.get_screenshot_as_file("D:\\1.jpg")
driver.close()

12.    cookie信息

from selenium import webdriver

driver = webdriver.Chrome()

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

cookie = driver.get_cookies()

print(cookie)

driver.quit()

13.    JavaScript实现滚动条滚动

js = "window.scrollTo(100,450);"

driver.execute_script(js)
