使用 By.LINK_TEXT 单击页面上的特定按钮，但 find_element 抛出异常

Question

在此页面上：https://finance.yahoo.com/quote/KO/options

这个按钮是：

<button class="tertiary-btn fin-size-small menuBtn tw-justify-center rounded rightAlign svelte-xhcwo" data-ylk="elm:inpt;elmt:menu;itc:1;sec:qsp-options;slk:date-select;subsec:date" type="button" aria-label="May 24, 2024" aria-haspopup="listbox" data-type="date" data-rapid_p="14" data-v9y="1">
  <div class="icon fin-icon inherit-icn sz-medium svelte-21xhfv">
    <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24">
      <path d="M16.59 8.59 12 13.17 7.41 8.59 6 10l6 6 6-6z"></path>
    </svg>
  </div>
  <span class=" textSelect svelte-q648fa">May 24, 2024</span>
</button>

我尝试了这段代码：

browser = webdriver.Firefox()
browser.get("https://finance.yahoo.com/quote/KO/options")
# The option expiraiton date will change based on when this script runs 
option_expiration_date = "May 24, 2024"
wait = WebDriverWait(browser, 20)
field = wait.until(EC.visibility_of_element_located((By.LINK_TEXT, option_expiration_date)))
elem = browser.find_element(By.LINK_TEXT, option_expiration_date)
elem.click()

但它抛出了这个异常：

Answer 1

这是使用基于 XPATH 的定位器单击该按钮的方法：

//[... imports, define browser, etc ... make sure browser's window is tall enough, at least 1500px]

wait = WebDriverWait(driver, 15)
driver.get('https://finance.yahoo.com/quote/KO/options?guccounter=1')
wait.until(EC.element_to_be_clickable((By.XPATH, '//button[@name="agree"]'))).click()
driver.get('https://finance.yahoo.com/quote/KO/options?guccounter=1')
wait.until(EC.element_to_be_clickable((By.XPATH, '//button[@aria-label="May 24, 2024"]'))).click()
