Question

我正在尝试从html表中获取数据，该表似乎根据下拉列表的值（使用默认值）在表上加载数据。但是，当我在下拉列表中执行selenium click（）时，表值会更改，但我得到的数据仍然来自旧页面。如何获取更新的值？这是我试过的代码。

注意：我正在尝试的网址是this one

from selenium import webdriver

browser = webdriver.Firefox()
browser.get(url)     # you can use the url linked above for example

if browser.find_element_by_xpath(
'//a[@id = "user-header-oddsformat-expander"]/span').text != 'IN Odds':
 # choose a type of odd that you want from the top dropdown menu
    browser.find_element_by_xpath(
    '//a[@id = "user-header-oddsformat-expander"]').click()
    browser.find_element_by_xpath(
    '//ul[@id = "user-header-oddsformat"]/li/a/span[contains(text(), "IN Odds")]').click()

browser.implicitly_wait(10)
table = browser.find_elements_by_css_selector('div#odds-data-table')

for elem in table:
    print elem.text

这里，即使在dong find_elements ...（）之前执行click（）之后，我仍然从原始加载的表中获取数据，而不是新表。我该怎么做？

使用text_to_be_present_in_element()等待“In Odds”作为下拉值：

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


url = "http://www.oddsportal.com/soccer/england/premier-league/aston-villa-chelsea-Ea6xur9j/?r=1#over-under;2"
browser = webdriver.Firefox()
browser.implicitly_wait(10)
wait = WebDriverWait(browser, 10)

browser.get(url)

if browser.find_element_by_xpath(
'//a[@id = "user-header-oddsformat-expander"]/span').text != 'IN Odds':
 # choose a type of odd that you want from the top dropdown menu
    browser.find_element_by_xpath(
    '//a[@id = "user-header-oddsformat-expander"]').click()
    browser.find_element_by_xpath(
    '//ul[@id = "user-header-oddsformat"]/li/a/span[contains(text(), "IN Odds")]').click()

    wait.until(EC.text_to_be_present_in_element((By.XPATH, '//a[@id = "user-header-oddsformat-expander"]/span'), "IN Odds"))


table = browser.find_elements_by_css_selector('div#odds-data-table')
for elem in table:
    print(elem.text)

如何在使用Selenium从下拉列表中选择后从表中获取更新数据？
