selenium语句

一、打开浏览器 （get）
案例1：打开一个浏览器
from selenium import webdriver
import time
dx=webdriver.Chrome()
dx.get("https://www.baidu.com/")

案例2：打开两个网址（覆盖）
from selenium import webdriver
import time
dx=webdriver.Chrome()
dx.get("https://www.baidu.com/")
time.sleep(2)
dx.get("https://www.jd.com/")

（3）打开两个网址（重开窗口）
from selenium import webdriver
import time
dx=webdriver.Chrome()
dx.get("https://www.baidu.com/")
time.sleep(2)
w="window.open('https://www.jd.com/')"
dx.execute_script(w)

二、时间等待
1、强制等待（不管能不能查找元素，都要等待规定的时间）
sleep
from selenium import webdriver
import time
dx=webdriver.Chrome()
dx.get("https://www.baidu.com/")
time.sleep(1)
dx.get("https://www.baidu.com/")

2、隐式等待（所在规定范围等待时间，如果提前找到元素，就节省时间）
语句：implicitly_wait
from selenium import webdriver
import time
dx=webdriver.Chrome()
dx.get("https://www.baidu.com/")
dx.implicitly_wait(10)
dx.get("https://www.baidu.com/")

3、显性等待

等待元素出现后，在进行下一步操作

三、refresh()刷新
from selenium import webdriver
import time
dx=webdriver.Chrome()
dx.get("https://www.baidu.com/")
time.sleep(3)
dx.refresh()

四、back 返回上一页
from selenium import webdriver
import time
dx=webdriver.Chrome()
dx.get("https://www.baidu.com/")
time.sleep(3)
dx.get("https://www.jd.com/")
time.sleep(3)
dx.back()

五、forward切换到下一页
from selenium import webdriver
import time
dx=webdriver.Chrome()
dx.get("https://www.baidu.com/")
time.sleep(3)
dx.get("https://www.jd.com/")
time.sleep(3)
dx.back()
time.sleep(3)
dx.forward()

六、set_window_size设置页面窗口大小
from selenium import webdriver
import time
dx=webdriver.Chrome()
dx.get("https://www.baidu.com/")
time.sleep(3)
dx.set_window_size(200,200)

七、maximize_window() 窗口最大化
from selenium import webdriver
import time
dx=webdriver.Chrome()
dx.get("https://www.baidu.com/")
time.sleep(3)
dx.maximize_window()

八、get_screenshot_as_file 截屏
from selenium import webdriver
import time
dx=webdriver.Chrome()
dx.get("https://www.baidu.com/")
time.sleep(3)
dx.get_screenshot_as_file(r"C:\Users\Administrator\Desktop\tupian\1.jpg")

九、close 关闭当前窗口

from selenium import webdriver
import time
dx=webdriver.Chrome()
dx.get("https://www.baidu.com/")
print(dx.title)
time.sleep(3)
w="window.open('https://www.jd.com/')"
dx.execute_script(w)
print(dx.title)
time.sleep(2)
dx.close()

十、quit 关闭所有的窗口

from selenium import webdriver
import time
dx=webdriver.Chrome()
dx.get("https://www.baidu.com/")
print(dx.title)
time.sleep(3)
w="window.open('https://www.jd.com/')"
dx.execute_script(w)
print(dx.title)
time.sleep(2)
dx.quit()

11、打印当前的抬头
from selenium import webdriver
import time
dx=webdriver.Chrome()
dx.get("https://www.baidu.com/")
print(dx.title)
time.sleep(3)
w="window.open('https://www.jd.com/')"
dx.execute_script(w)
print(dx.title)
time.sleep(2)
