python

  1、Webdriver 中调用JS，由于页面中的input是被隐藏起来的，所以必须用JS把隐藏的元素显示出来；

       browser.find_element_by_xpath("//div[@id=\'surveyItemsWrap\']/div/div[2]/button[2]").click()
        time.sleep(5)
        inputs=browser.find_element_by_xpath("//body/input")
        js="var q=document.getElementByClassName(\'ts_bg alert\');q.style.display=\'block\';"
        #  setAttribute(\"style\",\"display:block\     
        print "js"
        browser.execute_script(js)
        browser.find_element_by_xpath("//body/input").send_keys(\'F:\\Img\2.jpg\')
        print "ok"

 

报错：

Traceback (most recent call last):
  File "E:\eclipse\PythonCase\src\Survey_test\LogicMore.py", line 85, in test_Surveyor
    browser.execute_script(js)
  File "D:\Python27\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 396, in execute_script
    {\'script\': script, \'args\':converted_args})[\'value\']

    self.error_handler.check_response(response)

    raise exception_class(message, screen, stacktrace)

PS: JS有待加深学习！
