【问题描述】：

我写了一个 python 脚本来打开 seleniums chromedrive。然后自动进入苹果 iphone 11 商店页面，并自动开始填写选项以查找所有价格。

它执行以下操作

clicks) -> 1) no i don't have a phone to trade in 
clicks) -> 2) pro max 
clicks) -> 3) colour = grey 
clicks) -> 4) clicks on each storage options (64gb. 256gb, 512gb) get each price for all 3 phones and prints them.

问题，selenium 似乎没有正确点击第二个选项。并且只打印我想要的 3 个价格中的 2 个。为什么不点击第二个选项？

代码如下

import time
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.apple.com/uk/shop/buy-iphone/iphone-11-pro')
xpath_string = '//*[@id="tradeup-inline-app"]/div/div/fieldset/div/div[2]/div/div/label/span/span[2]';
WebDriverWait(driver,10).until(EC.presence_of_element_located((By.XPATH,xpath_string)))
python_button = driver.find_element_by_xpath(xpath_string)
python_button.click()
prices = []
def click(button):
    try:
        time.sleep(1)
        button.click()
        print('clicked   '  + str(button))
    except Exception as e:
        print(str(e))
        print(e)
        print('nope')


for i in range(2):
    if i == 0:
        xpath_string = '//*[@id="Item15_8inch_label"]/span';
        WebDriverWait(driver,10).until(EC.presence_of_element_located((By.XPATH,xpath_string)))
        size_button = driver.find_element_by_xpath(xpath_string)
                    click(size_button)
        
        xpath_string = '//*[@id="Item2space_gray_label"]/span[1]/div/img';
        WebDriverWait(driver,10).until(EC.presence_of_element_located((By.XPATH,xpath_string)))
        colour_button = driver.find_element_by_xpath(xpath_string)
        
        click(colour_button)

        for j in range(3):
            
            if j == 0:
                xpath_string = '//*[@id="Item3"]/div/fieldset/div/div[1]/div';
                WebDriverWait(driver,10).until(EC.presence_of_element_located((By.XPATH,xpath_string)))
                memory_button = driver.find_element_by_xpath(xpath_string)
            if j == 1: ###### this is the thjing its not clicking on (the 256gb button)
                xpath_string = '//*[@id="Item3"]/div/fieldset/div/div[2]/div';
                WebDriverWait(driver,10).until(EC.presence_of_element_located((By.XPATH,xpath_string)))
                memory_button = driver.find_element_by_xpath(xpath_string)
            if j == 2:
                xpath_string = '//*[@id="Item3"]/div/fieldset/div/div[3]/div';
                WebDriverWait(driver,10).until(EC.presence_of_element_located((By.XPATH,xpath_string)))
                memory_button = driver.find_element_by_xpath(xpath_string)        
            click(memory_button)

            xpath_string = '//*[@id="primary"]/materializer/purchase-options/fieldset/div/div[2]/div/div/div/label/span/span[2]/span';
            time.sleep(0.5)
            WebDriverWait(driver,10).until(EC.presence_of_element_located((By.XPATH,xpath_string)))
            price = driver.find_element_by_xpath(xpath_string)
            print(price)
            print(price.text)
            print('ppppppppppppppppppppppppppppppppppp')

        
    else:
        print("wtf")

当前输出（伪代码）

<complicated objects?>

£1,049.00

<complicated objects?>

£1,049.00

<complicated objects?>

£1,399.00

它显然没有点击第二个存储选项

想要的输出

<complicated objects?>

£1,049.00

<complicated objects?>

£1,199.00

<complicated objects?>

£1,399.00

实际输出

为什么不点击第二个选项？

【问题讨论】：

clicks) -> 2) pro max ;我想这是一个错字，因为您正在代码中寻找 5.8" 模型。

标签： python xpath selenium-chromedriver

【解决方案1】：

不需要点击存储选项来获取价格。您可以删除循环。 3 次点击（无以旧换新 + 模型 + 颜色）应该足够了。

点击后，获取价格：

xpath = "//div[@class='form-selector form-selector-rowwithgutters row']//div[@class='price-point price-point-fullPrice']/span"
tree = browser.find_elements_by_xpath(xpath)
for i in tree:
   print(i.text)

此外，对 3 次单击使用相对 XPath。顺序：

//div[@class="form-choice-selector-label"][./label[@for="noTradeIn"]]
//div[@class="form-choice-selector-label as-dimension-label"][./label[@id="Item15_8inch_label"]]
//div[@class="form-choice-selector-label as-dimension-label"][./label[@id="Item2space_gray_label"]]
