为什么selenium无法使用xpath或css选择器找到要单击的元素？

Question

我尝试单击此处页面上的“>”，但 chrome XPATH 或 CSS 选择器找不到它 https://theanalyst.com/na/2023/08/opta-football-predictions/

chrome full xpath 应该只适用于 selenium 吗？

import sys
import os
import pandas as pd
from selenium import webdriver
from pyvirtualdisplay import Display
import feyn_common

from bs4 import BeautifulSoup
from selenium import webdriver
import chromedriver_binary
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By


def parse_website():
    # Start a virtual display
    display = Display(visible=0, size=(800, 600))
    display.start()

    try:
        # Set Chrome options with the binary location
        chrome_options = webdriver.ChromeOptions()
        chrome_options.binary_location = "/usr/bin/google-chrome"

        # Initialize Chrome driver
        driver = webdriver.Chrome()

        # Open the desired URL
        url = "https://theanalyst.com/na/2023/08/opta-football-predictions/"
        driver.get(url)

        # Wait for the page to load completely (adjust the time as needed)
        # Parse the page source using BeautifulSoup
        predictions = WebDriverWait(driver, 10).until(
            EC.presence_of_all_elements_located(
                (By.CSS_SELECTOR, "iframe[src*=predictions]")
            )
        )
        element = driver.find_element_by_css_selector("#pos_3.div.fixtures-header.button:nth-child(3)")
        element.click()

Answer 1

认为有两个问题 - 第一个问题，您必须切换到 iframe 才能与其内容交互：

...
# Wait for the page to load completely (adjust the time as needed)
# Parse the page source using BeautifulSoup
driver.switch_to.frame(WebDriverWait(driver, 10).until(
    EC.presence_of_element_located(
        (By.CSS_SELECTOR, "#iFrameResizer1")
    )
))

其次，检查你的选择器，没有带有值的id

pos_3

element = driver.find_element(By.CSS_SELECTOR,"#pos_2 button")
element.click()
