1、使用JavaScript操作页面元素: 目的:在webdriver脚本代码中执行JavaScript代码,来实现对页面元素的操作,主要用于解决在某些情况下页面原色的Click方法无法生效问题; - # coding = utf-8
- from selenium import webdriver
- from selenium.common.exceptions import WebDriverException
- import unittest
- import traceback
- import time
- class TestDemo(unittest.TestCase):
- def setUp(self):
- self.driver = webdriver.Chrome(executable_path="D:\\software\\chromedriver")
- def test_executeScript(self):
- self.driver.get("http://www.baidu.com")
- # 构造JavaScript查找百度首页的搜搜输入框的代码字符串
- searchInputBoxJS = "document.getElementById('kw').value='光荣之路'"
- searchButtonBoxJS = "document.getElementById('su').click()"
- try:
- self.driver.execute_script(searchInputBoxJS)
- time.sleep(2)
- self.driver.execute_script(searchButtonBoxJS)
- time.sleep(2)
- self.assertTrue(u"百度百科" in self.driver.page_source)
- except WebDriverException:
- print(u"在页面中没有找到要操作的页面元素", traceback.print_exc())
- except AssertionError:
- print(u"页面不存在关键子串")
- except Exception:
- print(traceback.print_exc())
-
- def tearDown(self):
- self.driver.quit()
- if __name__ == '__main__':
- unittest.main()

2、操作Web页面滚动条: 目的:滑动页面的滚动条到页面最下面、滑动页面滚动条到页面某个元素、滑动页面的滚动条向下移动某个数量的像素; - # coding = utf-8
- from selenium import webdriver
- import unittest
- import traceback
- import time
- class TestDemo(unittest.TestCase):
- def setUp(self):
- self.driver = webdriver.Chrome(executable_path="D:\\software\\chromedriver")
- def test_scroll(self):
- try:
- self.driver.get("http:www.seleniumhq.org/")
- # 使用JavaScript的scrollTo函数和document.body.scrollHeight参数将页面的滚动条滑动到页面的最下方
- self.driver.execute_script("window.scrollTo(100,document.body.scrollHeight);")
- time.sleep(3)
- # 使用JavaScript的scrollIntoView函数将被遮挡的元素滚动到屏幕上,scrollIntoView(true)表示将元素滚动到屏幕中间,
- # false表示将元素滚动到屏幕底部
- self.driver.execute_script("document.getElementById('choice').scrollIntoView(true);")
- time.sleep(3)
- # 使用JavaScript的scrollBy方法使用0和400横纵坐标参数
- self.driver.execute_script("window.scrollBy(0,400);")
- time.sleep(3)
- except Exception:
- print(traceback.print_exc())
- def tearDown(self):
- self.driver.quit()
- if __name__ == '__main__':
- unittest.main()
