Question

我正在尝试从网站上抓取一些物品。

这是我的代码：

driver.get('https://www.planitbig.com/Categories/Office/Binders-and-Binding-Supplies/Binders.aspx')


soup=BeautifulSoup(driver.page_source,'html5lib')
soup=BeautifulSoup(driver.page_source,'html5lib')

table1 = soup.find( "table", {"id":"ctl00_MainContentHolder_ProductGridView1_dlProducts"} ).find_all(('div',{"class":"record"}))




for x in table1:
    table1=BeautifulSoup(str(table1),'html5lib')
    _link=table1.find('a',attrs={'class':'product_link'})
    print(_link)

由于某种原因，find_next / Find_all均返回保存值，即产品列表中的第一项。我在这里做错了什么

Answer 1

使用WebDriverWait()和CSS选择器生成visibility_of_element_located()并等待表可见。

代码：

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

driver=webdriver.Chrome()
driver.get('https://www.planitbig.com/Categories/Office/Binders-and-Binding-Supplies/Binders.aspx')
WebDriverWait(driver,10).until(EC.visibility_of_element_located((By.CSS_SELECTOR,"#ctl00_MainContentHolder_ProductGridView1_dlProducts")))
soup=BeautifulSoup(driver.page_source,'html5lib')
for link in soup.select("#ctl00_MainContentHolder_ProductGridView1_dlProducts .record .recordname>a[href]"):
    print(link['href'])

输出：
