python自动化测试selenium执行js脚本实现示例

from selenium import webdriver
from time import sleep
class TestScriptss(object):
 def setup(self):
  self.driver = webdriver.Chrome()
  self.driver.get(http://www.baidu.com) 
 #执行js提示框，并点确定
 def test_scripts(self):
  self.driver.execute_script("alert('test')")
  sleep(2)
  self.driver.switch_to.alert.accept()
  self.driver.quit() 
 #执行脚本获取当前页面标题
 def test_scripts(self):
  js = "return document.title"
  title = self.driver.execute_script(js)
  print(title)
  sleep(2)
  self.driver.quit()
 #格式化文本框
 def test_format(self):
  js = 'var q = document.getElementById("kw"); q.style.border="10px solid red"'
  self.driver.execute_script(js)
  sleep(5)
  self.driver.quit()
  #通过脚本实现页面滚动
 def test_scroll(self):
  self.driver.find_element_by_id('kw').send_keys('selenium test')
  self.driver.find_element_by_id('su').click()
  sleep(2)
  #搜索结果页面滚动
  js = 'window.scrollTo(0, document.body.scrollHeight)'
  # 同步执行
  self.driver.execute_script(js)
  #异步执行
  # self.driver.execute_async_script(js)
  sleep(2)
  self.driver.quit()
