1.網(wǎng)站模擬登錄

# douban.py

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import time

driver = webdriver.PhantomJS()
driver.get("http://www.douban.com")

# 輸入賬號(hào)密碼
driver.find_element_by_name("form_email").send_keys("xxxxx@xxxx.com")
driver.find_element_by_name("form_password").send_keys("xxxxxxxx")

# 模擬點(diǎn)擊登錄
driver.find_element_by_xpath("http://input[@class='bn-submit']").click()

# 等待3秒
time.sleep(3)

# 生成登陸后快照
driver.save_screenshot("douban.png")

with open("douban.html", "w") as file:
    file.write(driver.page_source)

driver.quit()

2.動(dòng)態(tài)頁(yè)面模擬點(diǎn)擊

3.執(zhí)行 JavaScript 語(yǔ)句

• 隱藏百度圖片

from selenium import webdriver

driver = webdriver.PhantomJS()
driver.get("https://www.baidu.com/")

# 給搜索輸入框標(biāo)紅的javascript腳本
js = "var q=document.getElementById(\"kw\");q.style.border=\"2px solid red\";"

# 調(diào)用給搜索輸入框標(biāo)紅js腳本
driver.execute_script(js)

#查看頁(yè)面快照
driver.save_screenshot("redbaidu.png")

#js隱藏元素，將獲取的圖片元素隱藏
img = driver.find_element_by_xpath("http://*[@id='lg']/img")
driver.execute_script('$(arguments[0]).fadeOut()',img)

# 向下滾動(dòng)到頁(yè)面底部
driver.execute_script("$('.scroll_top').click(function(){$('html,body').animate({scrollTop: '0px'}, 800);});")

#查看頁(yè)面快照
driver.save_screenshot("nullbaidu.png")

driver.quit()

• 模擬滾動(dòng)條滾動(dòng)到底部

# 
from selenium import webdriver
import time

driver = webdriver.PhantomJS()
driver.get("https://movie.douban.com/typerank?type_name=劇情&type=11&interval_id=100:90&action=")

# 向下滾動(dòng)10000像素
js = "document.body.scrollTop=10000"
#js="var q=document.documentElement.scrollTop=10000"
time.sleep(3)

#查看頁(yè)面快照
driver.save_screenshot("douban.png")

# 執(zhí)行JS語(yǔ)句
driver.execute_script(js)
time.sleep(10)

#查看頁(yè)面快照
driver.save_screenshot("newdouban.png")

driver.quit()
