为什么CSS选择器在等待元素可点击后不能点击元素？

Question

请参阅下面的代码。我想，除了最后一行，你可以忽略几乎所有的东西

from selenium import webdriver
import os
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
import xlsxwriter
from datetime import datetime
import time

chrome_driver = os.path.abspath('C:/Users/ross/Desktop/chromedriver.exe')
browser = webdriver.Chrome(chrome_driver)
browser.get('https://finra-markets.morningstar.com/BondCenter/Default.jsp')

WebDriverWait(browser, 60).until(EC.element_to_be_clickable((By.CSS_SELECTOR, '#TabContainer > div > div.rtq-tab-wrap > div.rtq-tab-menus-wrap > ul > li:nth-child(3) > a > span'))).click()

WebDriverWait(browser, 60).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "#ms-finra-advanced-search-form > div.ms-finra-advanced-search-btn > input:nth-child(2)"))).click()
WebDriverWait(browser, 60).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "#ms-agreement > input"))).click()

time.sleep(2)
WebDriverWait(browser, 60).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "#ms-finra-search-results > div > div.qs-resultData > div.qs-resultData-body > div.rtq-grid.rtq-grid-auto-h > div.rtq-grid-hd > div > div:nth-child(7) > div"))).click()
time.sleep(2)
whole_chart = WebDriverWait(browser, 60).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "#ms-finra-search-results > div > div.qs-resultData > div.qs-resultData-body > div.rtq-grid.rtq-grid-auto-h > div.rtq-scrollpanel > div.rtq-grid-scroll"))).text


parent = browser.find_element_by_xpath('//*[@id="ms-finra-search-results"]/div/div[3]/div[1]/div[1]/div[2]/div[2]/div')
count_divs = len(parent.find_elements_by_xpath("./div"))



for row_num in range(1):

    symbol = WebDriverWait(browser, 60).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "#ms-finra-search-results > div > div.qs-resultData > div.qs-resultData-body > div.rtq-grid.rtq-grid-auto-h > div.rtq-scrollpanel > div.rtq-grid-scroll > div > div:nth-child(" + str(row_num + 1) + ") > div:nth-child(3)"))).text

    maturity = WebDriverWait(browser, 60).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "#ms-finra-search-results > div > div.qs-resultData > div.qs-resultData-body > div.rtq-grid.rtq-grid-auto-h > div.rtq-scrollpanel > div.rtq-grid-scroll > div > div:nth-child(" + str(row_num + 1) + ") > div:nth-child(7)"))).text

    moody_rating = WebDriverWait(browser, 60).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "#ms-finra-search-results > div > div.qs-resultData > div.qs-resultData-body > div.rtq-grid.rtq-grid-auto-h > div.rtq-scrollpanel > div.rtq-grid-scroll > div > div:nth-child(" + str(row_num + 1) + ") > div:nth-child(8)"))).text

    sandp_rating = WebDriverWait(browser, 60).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "#ms-finra-search-results > div > div.qs-resultData > div.qs-resultData-body > div.rtq-grid.rtq-grid-auto-h > div.rtq-scrollpanel > div.rtq-grid-scroll > div > div:nth-child(" + str(row_num + 1) + ") > div:nth-child(9)"))).text

    bond_yield = WebDriverWait(browser, 60).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "#ms-finra-search-results > div > div.qs-resultData > div.qs-resultData-body > div.rtq-grid.rtq-grid-auto-h > div.rtq-scrollpanel > div.rtq-grid-scroll > div > div:nth-child(" + str(row_num + 1) + ") > div:nth-child(11)"))).text

    if symbol.strip() and maturity.strip() and moody_rating.strip() and sandp_rating.strip() and bond_yield.strip() and moody_rating != "WR" and sandp_rating != "NR":
        WebDriverWait(browser, 60).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "#ms-finra-search-results > div > div.qs-resultData > div.qs-resultData-body > div.rtq-grid.rtq-grid-auto-h > div.rtq-scrollpanel > div.rtq-grid-scroll > div > div:nth-child(" + str(row_num + 1) + ") > div:nth-child(2) > div > a"))).click()

        WebDriverWait(browser, 60).until(EC.element_to_be_clickable((By.CSS_SELECTOR,"#tradeHistory_link"))).click()

基本上，我进入了这个页面：https://finra-markets.morningstar.com/BondCenter/BondDetail.jsp?ticker=C724231&symbol=STWD4571190，我想要Selenium点击它上面的“交易历史”链接，所以我引用选择器“#交易历史_链接”。由于某些原因，它没有点击，当我尝试只获取文本时，它也不会得到。我也尝试过点击页面上的“交易历史”，然后点击。那没用。最后，我想可能页面还没有完全加载，所以我试着在点击“#tradeHistory_link”之前执行time.sleep（5），但没有效果

这是怎么回事

Answer 1

该元素驻留在iframe中，这可能是您无法单击它的原因。在Selenium能够与框架内的元素交互之前，您需要切换到该框架。在与该元素交互之前，请尝试添加此行

driver.switch_to.frame(driver.find_element_by_css_selector('#ms-bond-detail-iframe'))

Answer 2

Trade History链接存在于iframe内。为了访问链接，您需要首先切换到iframe

使用WebDriverWait（）并等待frame\u可用，然后将\u切换到\u it（），并使用元素ID

WebDriverWait(browser,10).until(EC.frame_to_be_available_and_switch_to_it((By.ID,"ms-bond-detail-iframe")))
WebDriverWait(browser,10).until(EC.element_to_be_clickable((By.CSS_SELECTOR,"#tradeHistory_link"))).click()

要从iframe出来，您需要切换到默认内容

browser.switch_to.default_content()

首先，尝试使用visibility_of_element_located预期条件而不是element_to_be_clickable。元素并不总是最终在其内部构建内部文本，并且当它变得可点击时。中的可见性通常会晚一点出现。
我还必须提到，你的css定位器看起来非常糟糕。你必须改进它们
