以下是示例代码

driver = webdriver.Chrome()
driver.get("https://www.footpatrol.co.uk/footwear/274670-nmd_r2-pk.html")
WebDriverWait(driver, 50).until(EC.presence_of_element_located((By.XPATH, "//form/fieldset/div[1]/div[2]/div/select/option[@value='181']"))).click()
size = driver.find_element_by_xpath("//form/fieldset/div[1]/div[2]/div/select/option[@value='181']")
# 
size.click()
driver.find_element_by_id('add-to-basket').click()

获得以下错误

Answer 1

这就是你的脚本的问题

1，而不是单击可见的元素（大小），您试图选择大小（背景）元素。

可见的size元素是一个链接，我认为在后台调用dropdown html元素并选择大小。因此，如果您只是单击可见的大小元素（链接）而不是单击下拉列表，那么您可以查找。

使用firebug工具检查特定元素的html。

driver = webdriver.Chrome()
driver.get("https://www.footpatrol.co.uk/footwear/274670-nmd_r2-pk.html")
size = WebDriverWait(driver, 50).until(EC.presence_of_element_located((By.XPATH, "//ul[@class='attribute_value_list']//li/a[text()='8']")))
size.click()
driver.find_element_by_id('add-to-basket').click()

请注意，请了解如何构建 XPath 和 CSS 选择器以选择特定元素。你使用的xpath是非常日志的，即使大小上最小的东西会改变也容易破坏。

Answer 2

以下是您的问题的答案：

您为<div class="container"> <div class="sidebarcontainer"> <div class="innersidebarcontainer"> <div class="sidebar"> </div> </div> </div>  <div class="mainpage"> <div class="page"> <h1>page</h1> </div> </div> </div> <div class="footer"></div>构建的xpath指的是8上的其他元素。我们需要为元素构造一个唯一的HTML DOM。以下是点击xpath然后点击8的示例代码：

ADD TO BASKET

如果这回答你的问题，请告诉我。

Answer 3

如果presence_of_element_located不起作用，请尝试visibility_of_element_located

例如，代替：

WebDriverWait(driver, 50).until(EC.presence_of_element_located((By.XPATH, "//form/fieldset/div[1]/div[2]/div/select/option[@value='181']"))).click()

尝试：

WebDriverWait(driver, 50).until(EC.visibility_of_element_located((By.XPATH, "//form/fieldset/div[1]/div[2]/div/select/option[@value='181']"))).click()

Answer 4

WebDriverWait(driver, 50).until(EC.presence_of_element_located((By.XPATH, "//form/fieldset/div[1]/div[2]/div/select/option[@value='181']"))).click()

有时.click（）不起作用。 stackoverflow中有很多与此相关的问题，但没有人真正有效。有时帮助Javascript执行者。随意在评论中提问

解决问题的第二种方法，试试这个：

JavascriptExecutor executor = (JavascriptExecutor)driver;
executor.executeScript("document.getElementById('add-to-basket').setAttribute('visibility', 'true');");

driver.findElement(By.id("add-to-basket")).click();
