现在我的脚本转到页面并从下拉列表中打开第二个对象“Vijesti”,然后才收到错误消息.
这是错误：
StaleElementReferenceException: Message: Element not found in the cache – perhaps the page has changed since it was looked up
来自Selenium网站：
Thrown when a reference to an element is Now “stale”.
Stale means the element no longer appears on the DOM of the page.
Possible causes of StaleElementReferenceException include,but not limited to:
- You are no longer on the same page,or the page may have refreshed since the element was located.
- The element may have been removed and re-added to the screen,since it was located. Such as an element being relocated. This can happen typically with a javascript framework when values are updated and the node is rebuilt.
- Element may have been inside an iframe or another context which was refreshed.
我想要选择每个对象,然后打开它.
这是来自url的SELECT部分：
<select id="kategorija" name="kategorija"> <option value="0">Kategorija</option> <option value="12">Vijesti</option> <option value="8">Biznis</option> <option value="5">Sport</option> <option value="2">Magazin</option> <option value="7">Lifestyle</option> <option value="3">Scitech</option> <option value="6">Auto</option> </select>
码：
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import Select
import time
driver = webdriver.Firefox()
driver.get("http://www.klix.ba/")
assert "Klix" in driver.title
elem = driver.find_element_by_name("q")
elem.send_keys("test")
elem.send_keys(Keys.RETURN)
select = Select(driver.find_element_by_name('kategorija'))
all_options = [o.get_attribute('value') for o in select.options]
for x in all_options:
select.select_by_value(x)
time.sleep(3)
这是我做测试的url.
解决方法
从下拉列表中选择项目时,页面会自动刷新.
您需要“重新”选择每个选项上的select元素：
select = Select(driver.find_element_by_name('kategorija'))
for index in range(len(select.options)):
select = Select(driver.find_element_by_name('kategorija'))
select.select_by_index(index)
# grab the results
