如何按下帶有父類名稱的按鈕？

我正在嘗試制作一個可以使用父類名稱為我按下按鈕的機器人。

我的代碼：

import time
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.ui import Select

browser = webdriver.Chrome('C:/Users/rober/OneDrive/Skrivebord/bot/chromedriver')

# Graffik kort
browser.get("https://www.zalando.dk/jordan-air-jordan-1-mid-sneakers-high-joc12n001-a18.html")

buyButton = False

while buyButton is False:

    try:
        
        addToCartBtn = addButton = browser.find_element_by_xpath('/html/body/div[4]/div/div[2]/div/div/div[2]/div[1]/x-wrapper-re-1-6/div/div[4]/button')

        print("Varen er udsolgt")

        time.sleep(1)
        browser.refresh()

    except:
        addToCartBtn = addButton = browser.find_element_by_xpath('//*[@id="picker-trigger"]')

        print("Varen er p? Lager")
        buyButton = True

while buyButton is True:
    time.sleep(1)
    WebDriverWait(browser, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "button.uc-btn#uc-btn-accept-banner"))).click()
    WebDriverWait(browser, 20).until(EC.element_to_be_clickable((By.XPATH, "//span[text()='V?lg st?rrelse']"))).click()
    browser.execute_script("return arguments[0].scrollIntoView(true);", WebDriverWait(browser, 20).until(EC.visibility_of_element_located((By.XPATH, "//label[starts-with(@for, 'size-picker')]//span[text()='51.5']"))))
    WebDriverWait(browser, 20).until(EC.element_to_be_clickable((By.XPATH, "//label[starts-with(@for, 'size-picker')]//span[text()='51.5']"))).click()
    WebDriverWait(browser, 20).until(EC.element_to_be_clickable((By.XPATH, "//span[text()='L?g i indk?bskurv']"))).click()
    WebDriverWait(browser, 20).until(EC.presence_of_element_located((By.CSS_SELECTOR, 'a[title="Indk?bskurv"]'))).click()
    WebDriverWait(browser, 10).until(EC.presence_of_element_located((By.CSS_SELECTOR, 'z-1-button z-coast-base-primary-accessible z-coast-base__totals-tile__button-checkout z-1-button--primary z-1-button--button'))).click()

我試過的：

WebDriverWait(browser, 10).until(EC.presence_of_element_located((By.CSS_SELECTOR, 'z-1-button z-coast-base-primary-accessible z-coast-base__totals-tile__button-checkout z-1-button--primary z-1-button--button'))).click()

錯誤：

selenium.common.exceptions.TimeoutException: Message:

網站：

如果是，那么您可以使用以下代碼單擊它：

WebDriverWait(browser, 10).until(EC.visibility_of_element_located((By.XPATH, "//*[@class='z-coast-base__totals-tile']//*[@class='z-1-button__content']"))).click()

如果你本質上想要一個 CSS SELECTOR 而不是 xpath，你可以用這個替換它：

WebDriverWait(browser, 10).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "div[class='z-coast-base__totals-tile'] div[class='z-1-button__content']"))).click()

甚至這個：

WebDriverWait(browser, 10).until(EC.visibility_of_element_located((By.CSS_SELECTOR, ".z-coast-base__totals-tile .z-1-button__content"))).click()

另外，我看到您使用的 Webelement 定位器addToCartBtn很差。這是絕對的，非常不可靠。盡量使它們相對。我指的是這個：/html/body/div[4]/div/div[2]/div/div/div[2]/div[1]/x-wrapper-re-1-6/div/div[4]/button

uj5u.com熱心網友回復：

我使用SeleniumBase創建了一個帶有解決方案的簡化腳本。pip install seleniumbase，然后將該代碼放入 Python 檔案中，然后使用pytest.

from seleniumbase import BaseCase


class MyTestClass(BaseCase):
    def test_base(self):
        self.open("https://www.zalando.dk/jordan-air-jordan-1-mid-sneakers-high-joc12n001-a18.html")
        self.click("button#uc-btn-accept-banner")
        self.click("button#picker-trigger")
        self.click('label[for="size-picker-JOC12N001-A180170000"] span span')
        self.click('button[aria-label="L?g i indk?bskurv"]')
        self.click('a[title="Indk?bskurv"] svg')
        self.click('button:contains("Videre til kassen")')
