JS 操作页面元素

在webdriver中主要用来解决点击无法生效问题 代码如下：

 

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()

    def test_executeScript(self):
        url='http://www.baidu.com'
        self.driver.get(url)
        #Javascript查找百度页面输入框代码字符串
        BoxJs='document.getElementById("kw").value="学艺的海盗";'
        #构造Javascript查询百度页面搜索按钮代码字串符
        Js='document.getElementById("su").click()'
        try:
            self.driver.execute_script(BoxJs)
            time.sleep(2)
            self.driver.execute_script(Js)
            time.sleep(3)
            self.assertTrue(u'贴吧百度' in self.driver.page_source)
        except WebDriverException as e:
            print(u'在页面没有要找到的元素',traceback.print_exc(),e)
        except AssertionError as e:
            print(u'页面不存在断言关键字',e)
        except Exception as e:
            print(traceback.print_exc(),e)

    def tearDown(self):
        self.driver.quit()
if __name__ == '__main__':
    unittest.main()
