Question

我需要使用python的web驱动程序的帮助。我试图使用等待迭代下拉列表。选定的下拉项会自动更新页面，因此需要使用webdriverwait来提供页面更新时间。需要遍历10个项目的下拉列表并在每个项目之间等待。关于如何做到这一点的任何例子？

您想要做的一般模式可能是：

创建对item to select, condition to wait for after selection
在此列表中循环

我不是一个python开发人员，所以请将下面的代码作为伪代码使用python flavor：

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.ui import Select

# First item in tuple is the value of select, 
# Second is the value to wait for after selecting the item
verify_list = [('item1', '//xpath1'),('item2', '//xpath2'),...]

wait = WebDriverWait(driver, 10)

for item,condition in verify_list:

    # Get select itself (since page refreshes, you may need to do it after each select)
    select = Select(driver.find_element_by_xpath("xpath"))

    # Select the value (for example by visible text)
    select.select_by_visible_text(item)

    # Wait for condition. For example presence of the element
    # try/catch can be added here, if you want to run all options, 
    # even if one of them fails.
    wait.until(EC.presence_of_element_located((By.XPATH, condition))

迭代webdriver下拉列表时无法等待
