StaleElementReferenceException: element is not attached to the page document while selecting the options from multiple Dropdowns using Selenium Python

问题

Code trial:

#coding=utf-8

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']"))))
        for item2 in select2.options:
            item2.click()
            time.sleep(2)

            # below is to get the attained date into excel file
            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()

I have edited this code thanks to the lovely comment below but I get the same error saying as below.:

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

I roughly understand why this message shows up but still have no clear idea on how to fix this. I would deeply appreciate any comment! Many thanks in advance!

This is what I figured out. But I'm not sure if code is right or not. I don't know 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)

To select all the <option> elements from multiple e.g. two (2) different drop-down-select elements within the website https://price.joinsland.joins.com/theme/index_theme.asp?sisaegbn=T05 you need to induce WebDriverWait for the element_to_be_clickable() and you can use the following xpath based Locator Strategies:

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
