使用Selenium單擊表中的特定鏈接-有解無憂

我必須從此鏈接收集資料：https : //datacentersupport.lenovo.com/gb/en/products/storage/fiber-channel-switches/b6505-fc-san-switch/3873/parts/display/compatible

但是，我在訪問替代品下的資料時遇到了困難（注意：并非所有人都有替代品）。那些有替代品的看起來像這樣：

使用 Selenium 單擊表中的特定鏈接

鏈接的第 2 頁上有一個示例

請幫我完成代碼，我必須收集替代品的零件號。

這是我的代碼：

from selenium import webdriver
from time import sleep
import csv

# initializing webdriver 
driver = webdriver.Chrome(executable_path="~~chromedriver.exe")
url = "https://datacentersupport.lenovo.com/gb/en/products/storage/fibre-channel-switches/b6505-fc-san-switch/3873/parts/display/compatible"
driver.get(url)
sleep(5)

#getting breadcrumbs
bread1 = driver.find_element_by_xpath("//span[@class='prod-catagory-name']")
bread2 = driver.find_element_by_xpath("//span[@class='prod-catagory-name']/a")

#grabbing table data and navigating 
pages = int(driver.find_element_by_xpath("//div[@class='page-container']/span[@class='icon-s-right active']/preceding-sibling::span[1]").text)
num = pages -1 
for _ in range(num):
     rows = driver.find_elements_by_xpath("//table/tbody/tr/td[2]/div")
     for row in rows:
         parts = row.text
         with open(filename, 'a', encoding='utf-8') as file:
             file.write(url   ","   bread1.text   ","   bread2.text   ","   parts   "\n")

     pagination = driver.find_element_by_xpath("//div[@class='pagecontainer']/span[@class='icon-s-right active']").click()
     sleep(5)
driver.close()

如果我需要更改或修改代碼以獲取替代品，請告訴我。

uj5u.com熱心網友回復：

要訪問網頁中替代品下的資料，您需要展開替代品誘導WebDriverWait for the visibility_of_all_elements_located()，您可以使用以下任一定位器策略：

代碼塊：

driver.get("https://datacentersupport.lenovo.com/gb/en/products/storage/fibre-channel-switches/b6505-fc-san-switch/3873/parts/display/compatible")
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "span.icon-select-down"))).click()
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//span[contains(., '20')]"))).click()
for element in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "span[class='icon-s-down']"))):
    element.click()
    print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//span[@class='icon-s-up']//following::tr[3]/td[contains(@class,'enabled-border')]//div[text()]"))).text)
