我一直试图从本网站中抓取数据.我需要填写获取您汽车的准确价格表格，即.年份，品牌，型号等.到目前为止，我已经编写了以下代码:

I have been trying to scrape data from this site. I need to fill Get the precise price of your car form ie. the year, make, model etc.. I have written the following code till now:

import requests
import time
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.ui import WebDriverWait, Select
from selenium.common.exceptions import NoSuchElementException
from selenium.common.exceptions import StaleElementReferenceException
from selenium.webdriver.support import expected_conditions
from bs4 import BeautifulSoup
import re

chrome_options = webdriver.ChromeOptions()
driver = webdriver.Chrome('chromedriver_win32/chromedriver.exe', options=chrome_options)
url = "http://www.indianbluebook.com/"
driver.get(url)
save_city = driver.find_element_by_xpath('//*[@id="cityPopup"]/div[2]/div/div[2]/form/div[2]/div/a[1]').click()  #Bangalore

#fill year
year_dropdown = Select(driver.find_element_by_xpath('//*[@id="car_value"]/div[2]/div[1]/div[1]/div/select'))
driver.implicitly_wait(50)
year_dropdown.select_by_value('2020')

time.sleep(5)

但是，它给出了这个错误:

But, its giving this error:

注意:我在互联网上尝试了许多可用的解决方案，例如使用 WebDriverWait 的预期条件.有时我会收到错误，StaleElementException.我现在不知道该怎么办.请帮忙.我是新手.

Note: I have tried many available solutions on internet like using Expected conditions with WebDriverWait. Sometimes I get the error, StaleElementException. I don't know what to do now. Please help. I'm new to this.

推荐答案

您可以使用以下方法来实现相同的效果.

You can use the below approach to achieve the same.

#Set link according to data need
driver.get('http://www.indianbluebook.com/')

#Wait webpage to fully load necessary tables
def ajaxwait():
    for i in range(1, 30):
        x = driver.execute_script("return (window.jQuery != null) && jQuery.active")
        time.sleep(1)
        if x == 0:
            print("All Ajax element loaded successfully")
            break


ajaxwait()
wait = WebDriverWait(driver, 20)
wait.until(EC.element_to_be_clickable((By.XPATH, "//*[@id='cityPopup']/div[2]/div/div[2]/form/div[2]/div/a[1]")))

save_city = driver.find_element_by_xpath('//*[@id="cityPopup"]/div[2]/div/div[2]/form/div[2]/div/a[1]').click()  #Bangalore

ajaxwait()
#fill year
wait.until(EC.element_to_be_clickable((By.XPATH, "//div[@class='form-group']//select[@class='form-control' and @name='manufacture_year']/following-sibling::div/a")))
#//div[@class='form-group']//select[@class='form-control' and @name='manufacture_year'] this is the only unique elemnt with reference to this we can find other element.
#click on select year field then a dropdown will be open we will enter the year in the input box. Then select the item from the ul list.
driver.find_element_by_xpath("//div[@class='form-group']//select[@class='form-control' and @name='manufacture_year']/following-sibling::div/a").click()
driver.find_element_by_xpath("//div[@class='form-group']//select[@class='form-control' and @name='manufacture_year']/following-sibling::div//input").send_keys("2017")
driver.find_element_by_xpath("//div[@class='form-group']//select[@class='form-control' and @name='manufacture_year']/following-sibling::div//em").click()

同样，您可以通过更改 @name='manufacture_year' 属性值来选择其他下拉列表.

Similarly you can select other drop down by changing the @name='manufacture_year' attribute value.

注意:使用 Ajax 等待更新了代码.

Note: Updated the code with Ajax wait.
