<option title="Generic_Eng" value="Generic_Eng">Generic_Eng</option>

我尝试使用此代码.使用此代码,我可以选择第一个选项,即"P0_ENGLISH".但是,选择第一个选项后,我得到一个错误:
I've tried using this code. With this code, I am able to select the first option i.e. "P0_ENGLISH". However, after selecting the first option I get an error:
selenium.common.exceptions.StaleElementReferenceException: Message: stale element reference: element is not attached to the page document
推荐答案
要从 Multi Select 元素中选择多个选项,可以使用 ActionChains 模拟控制点击,如下所示:
To select multiple options from a Multi Select element you can use ActionChains to mock Control Click as follows:
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.common.keys import Keys
myElemA = driver.find_element_by_css_selector(".rowStyle1:nth-child(6) .gwt-ListBox option[value='P0_English']")
myElemB = driver.find_element_by_css_selector(".rowStyle1:nth-child(6) .gwt-ListBox option[value='P1_English']")
myElemC = driver.find_element_by_css_selector(".rowStyle1:nth-child(6) .gwt-ListBox option[value='P5_English']")
ActionChains(driver).key_down(Keys.CONTROL).click(myElemA).key_up(Keys.CONTROL).perform()
ActionChains(driver).key_down(Keys.CONTROL).click(myElemB).key_up(Keys.CONTROL).perform()
ActionChains(driver).key_down(Keys.CONTROL).click(myElemC).key_up(Keys.CONTROL).perform()
