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()
