Webdriver搞不定的,需要用js,无需引入有关js的包就可用
在WebDriver脚本代码中执行JavaScript代码,来实现对页面元素的操作。此方法主要用于解决在某些情况下,页面元素的.click()方法无法生效等问题。
#encoding=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): # 启动Chrome浏览器 #self.driver = webdriver.Chrome(executable_path = "c:\\chromedriver") self.driver = webdriver.Ie(executable_path = "e:\\IEDriverServer") def test_executeScript(self): url = "http://www.sogou.com" # 访问baidu首页 self.driver.get(url) # 构造JavaScript查找百度首页的搜索输入框的代码字符串 searchInputBoxJS = "document.getElementById(‘query‘).value=‘光荣之路‘;" # 构造JavaScript查找百度首页的搜索按钮的代码字符串 searchButtonJS = "document.getElementById(‘stb‘).click()" try: # 通过JavaScript代码在百度首页搜索输入框中输入“光荣之路” self.driver.execute_script(searchInputBoxJS) time.sleep(2) # 通过JavaScript代码点击百度首页上的搜索按钮 self.driver.execute_script(searchButtonJS) time.sleep(2) self.assertTrue(u"光荣之路" in self.driver.page_source) except WebDriverException, e: # 当定位失败时,会抛出WebDriverException异常 print u"在页面中没有找到要操作的页面元素 ",traceback.print_exc() except AssertionError, e: print u"页面不存在断言的关键字串" except Exception, e: # 发生其他异常时,打印异常堆栈信息 print traceback.print_exc() def tearDown(self): # 退出IE浏览器 self.driver.quit() if __name__ == ‘__main__‘: unittest.main()
解释:
>>> try:
... 1/0
... except:
... print "error"
...
error
>>> import traceback
>>> try:
... 1/0
... except:
... traceback.print_exc()
...
