代码试用。

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import Select, WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
import time
import pandas as pd 

# Below is to crawl data from a webpage with two different dropdown
try:
    driver = webdriver.Chrome('./chromedriver')


    driver.get('https://price.joinsland.joins.com/theme/index_theme.asp?sisaegbn=T05')

    select1 = Select(WebDriverWait(driver, 5).until(EC.element_to_be_clickable((By.XPATH, "//select[@name='sido']"))))
    for item1 in select1.options:
        item1.click()
        select2 = Select(WebDriverWait(driver, 5).until(EC.element_to_be_clickable((By.XPATH, "//select[@name='gugun']"))))

            table = driver.find_element_by_class_name('tbl_box')
            tbody = table.find_element_by_tag_name('tbody')
            rows=tbody.find_elements_by_tag_name('tr')


            total = []
            result = []
            for index, value in enumerate(rows):
                body = value.find_elements_by_tag_name('td')

                for i in range(len(body)):
                    data = body[i].text
                    result.append(data)

            total.append(result)
            result=[]

        df = pd.DataFrame.from_records(total)
        df.to_excel('text.xlsx')



except Exception as e:
    print(e)

finally:
    driver.quit()

我编辑了这段代码 感谢下面可爱的评论 但是我得到了和下面一样的错误信息... ..:

Message: stale element reference: element is not attached to the page document

我大致明白了为什么会出现这样的信息 但我还是不知道该如何解决这个问题。我将深深地感谢任何评论! 非常感谢!

Answer 1

这是我想出来的。但我不确定代码是否正确。我不懂python。

#get select
select1 = Select(driver.find_element_by_xpath('//select[@name="sido"]'))

#get all options from select
options1 = select1.options

for opt1 is options1:

    #select the option which has the value of opt1
    select1.select_by_value(opt1.get_attribute("value"))
    time.sleep(5)

    select2 = Select(driver.find_element_by_xpath('//select[@name="gugu"]'))
    options2 = select2.options

    for opt2 in options2:
        select1.select_by_value(opt2.get_attribute("value"))
        time.sleep(4)

Answer 2

要选择所有的 <option> 的元素，如两（2）种不同的 下拉选择 网站内的元素 https:/price.joinsland.joins.comthemeindex_theme.asp?sisaegbn=T05。 你需要诱导 WebDriverWait 对于 element_to_be_clickable() 您可以使用以下方法 xpath 基于 定位策略:

driver.get('https://price.joinsland.joins.com/theme/index_theme.asp?sisaegbn=T05')
select1 = Select(WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//select[@name='sido']"))))
for item1 in select1.options:
    item1.click()
    select2 = Select(WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//select[@name='gugun']"))))
    for item2 in select2.options:
        item2.click()
        time.sleep(3) # perform your web-crawling here
