Question

所以我有点卡住了！我正在尝试从“所有评论”下拉菜单中选择一个项目，但是它不会像我可以选择每个元素然后单击它的位置那样进行交互。

相反，行为就像一个元素，在其标签更改时显示不同的结果。有谁知道我该如何从菜单中选择一个元素？

例如，使菜单从下拉菜单中选择“ Google”标签。

Answer 1

出现此特定网页元素时，其中许多元素不仅仅存在于DOM内容中，您应该使用WebDriverWait方法来等待直到找到特定元素。

例如，让我们根据您的要求选择“ Google”：

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

driver = webdriver.Chrome()
driver.get("the google link here, it's too big to paste it")

#Waiting until dropdown is visible , there are two dropdowns, taking the first one
menu = WebDriverWait(driver,5).until(EC.visibility_of_element_located((By.XPATH, " 
(//div[@class='cYrDcjyGO77__container'])[1]")))
menu.click()

#Waiting untill menu items is visible then selecting the second element - Google
item = WebDriverWait(driver,5).until(EC.visibility_of_element_located((By.XPATH, " 
(//div[@role='menuitem'])[2]")))
item.click()

Answer 2

您可以做的是找到您的下拉列表，然后列出所有选项并选择您的选项。这是我的做法

el = driver.find_element_by_id("dropdown_id")
for option in el.find_elements_by_tag_name('option'):
    if "GB" in option.text:
        option.click() # select() in earlier versions of webdriver
        break

我正在选择状态为“ GB”的下拉菜单。

Answer 3

引入WebDriverWait（）和element_to_be_clickable（），然后单击All reviews div元素以打开下拉菜单，然后基于文本选择项目。

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

driver=webdriver.Chrome()
driver.get("https://www.google.com/maps/place/Hilton+London+Bankside/@51.5056536,-0.1033145,17z/data=!3m1!4b1!4m10!3m9!1s0x487604af6af74cc7:0x6c4cb3cbe03e95bf!5m2!4m1!1i2!8m2!3d51.5056536!4d-0.1011258!9m1!1b1")
#Dropdown text provide here
selectItem='Agoda'
#First click on the All reviews element to open up the dorpdown element
WebDriverWait(driver,10).until(EC.element_to_be_clickable((By.CSS_SELECTOR,"div[aria-label='All reviews']"))).click()
#Select item from menu dropdown by text
WebDriverWait(driver,10).until(EC.element_to_be_clickable((By.XPATH,"//div[@role='menuitem']//div[text()='"+ selectItem +"']"))).click()
