蟒硒先锋：NoSuchElementException异常：没有这样的元件：无法与硒和Python定位元件

Question

我试图下载历史数据，然后单击链接到的历史数据。然而，即使Xcode是正确的我得到这个错误：

NoSuchElementException: no such element: Unable to locate element.

代码试验：

from selenium.webdriver.support.ui import WebDriverWait
from selenium import webdriver
driver = webdriver.Chrome(executable_path='/Users/Documents/Coding/chromedriver')
url = "https://www.vanguardinvestor.co.uk/investments/vanguard-lifestrategy-100-equity-fund-accumulation-shares/price-performance?intcmpgn=blendedlifestrategy_lifestrategy100equityfund_fund_link"
driver.get(url)
wait = WebDriverWait(driver, 10)
elem = driver.find_element_by_xpath("//*[@id='prices-and-performance-tab']/div/div[4]/div[3]/div[1]/div[1]/div[3]/div/div/div[2]/div/table/tfoot/tr/td/a")
webdriver.ActionChains(driver).move_to_element(elem).click(elem).perform()

Answer 1

点击元素上等待页面加载和元素，可以点击，然后click.Try整个片段。

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

driver = webdriver.Chrome(executable_path='/Users/Documents/Coding/chromedriver')
url = "https://www.vanguardinvestor.co.uk/investments/vanguard-lifestrategy-100-equity-fund-accumulation-shares/price-performance?intcmpgn=blendedlifestrategy_lifestrategy100equityfund_fund_link"
driver.get(url)
element = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//span[text()[contains(.,'Price & Performance')]]")))
element.click

Answer 2

点击与文本搜索您需要诱导WebDriverWait的元素是可以点击的，您可以使用以下解决方案的更多历史的元素：

• 代码块：

  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
  
  options = webdriver.ChromeOptions()
  options.add_argument("--start-maximized")
  options.add_argument("--disable-extensions")
  driver = webdriver.Chrome(chrome_options=options, executable_path = r'C:\Utility\BrowserDrivers\chromedriver.exe' ) 
  driver.get("https://www.vanguardinvestor.co.uk/investments/vanguard-lifestrategy-100-equity-fund-accumulation-shares/price-performance?intcmpgn=blendedlifestrategy_lifestrategy100equityfund_fund_link")
  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//button[@id='bannerButton']"))).click()
  more_historical_prices = WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.LINK_TEXT, "Search for more historical prices")))
  driver.execute_script("arguments[0].scrollIntoView(true);", more_historical_prices)
  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.LINK_TEXT, "Search for more historical prices")))
