如何使用硒从非选择下拉菜单中单击项目

Question

[尝试选择其他财务报表（默认为损益表），以及在第二个年度/季度列表之间切换。我可以缩小范围以获取列表的属性，但无法与列表进行交互。

import time
import urllib.request
from bs4 import BeautifulSoup
from selenium import webdriver

symbol = 'bmo'
driver = webdriver.Chrome()
driver.get('https://web.tmxmoney.com/financials.php?qm_symbol={}'.format(symbol))
time.sleep(2)
dropdown = driver.find_elements_by_css_selector('a.qmod-dropdown_toggle.qmod-type-toggle + ul.qmod-dropdown-menu > li > a')

for option in dropdown:
    if option.get_attribute('innerText') == 'Balance Sheet':
        option.send_keys('Balance Sheet')

Answer 1

要选择文本为资产负债表的dropdown选项，必须为element_to_be_clickable()引入WebDriverWait，并且可以使用以下Locator Strategies：

• xpath：

  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
  
  driver.get('https://web.tmxmoney.com/financials.php?qm_symbol=bmo')
  element = WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//h4[text()='Financials for Bank of Montreal']")))
  driver.execute_script("window.scrollBy(0,600)")
  ActionChains(driver).move_to_element(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//a[@class='qmod-dropdown_toggle qmod-type-toggle']/span[text()='Income Statement']")))).perform()
  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//ul[@class='qmod-dropdown-menu']//li/a[text()='Balance Sheet']"))).click()
