无法使用selenium.webdriver单击列表中的项目

Question

我想按位置进一步筛选搜索结果。我只想要“美国”的结果，所以要单击“美国”，其顺序根据关键字的不同而变化。
以下代码不起作用。没有错误消息，但什么也没有发生。谢谢大家!

  browser.implicitly_wait(30)
  element = browser.find_element_by_xpath("//span[contains(text(),'United 
  States')]")

  browser.execute_script("arguments[0].click();", element)

如果成功，则“美国”也应出现在狭义By列表中：

The HTML source is as follows:

    <ul class="supplemental filters  " aria-labelledby="podfiltersbuttonlocation" data-id="location">
                <li class="preferred">
                    <h3 class="closable">
                        <span>
                            Select location by publications to display at the top of this list. <a 
    href="#" data-action="editpreferred">Edit Settings</a>
                        </span>
                        <button data-action="dismisspreferred" type="button" class="icon la-

Answer 1

点击checkbox诱导WebDriverWait（）和element_to_be_clickable（）和后面的Xpath

WebDriverWait(driver,20).until(EC.element_to_be_clickable((By.XPATH,"//ul[@class='supplemental filters  ']//li[.//span[text()='United States']]/input[@type='checkbox']"))).click()

您需要导入以下库

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