这里是元素 HTML 代码：

这里是这个元素代码：

<span class="_18vi"><a class=" _2nj7 _18vj _18vk" data-ft="{ &quot;tn&quot;: &quot;J&quot;, &quot;type&quot;: 25 }" href="/ajax/sharer/?s=22&amp;appid=25554907596&amp;id=1816791348467451&amp;p[0]=130584170421519&amp;p[1]=1816792805133972&amp;sharer_type=all_modes&amp;av=130584170421519" rel="dialog" role="button" tabindex="0" title="Send this to friends or post it on your timeline.">Share</a></span>

这是我的代码：

我

return element if element.is_displayed() == visibility else False

Answer 1

我测试了您的问题（在 MacOS Mojave 上）并成功点击了 facebook 上的分享按钮： 解决方案：代码执行时点击两次click_Share

click_Share=WebDriverWait( driver, 50).until(EC.element_to_be_clickable((By.XPATH, "//*[@id='u_1b_2']/div[2]/div/div[2]/div/span[3]/a/text()"))).click()
click_Share=WebDriverWait( driver, 50).until(EC.element_to_be_clickable((By.XPATH, "//*[@id='u_1b_2']/div[2]/div/div[2]/div/span[3]/a/text()"))).click()

我认为这个问题可能是一些与 Facebook 相关的一次性问题。大多数网站上的可点击元素只需单击一下即可。

更新答案：

您也可能获取了错误的 XPATH，请替换您的代码行：

click_Share=WebDriverWait( driver, 50).until(EC.element_to_be_clickable((By.XPATH, "//*[@id='u_1b_2']/div[2]/div/div[2]/div/span[3]/a/text()"))).click()

用这一行：

click_Share=WebDriverWait( driver, 50).until(EC.element_to_be_clickable((By.XPATH, "//*[@id='u_g_2']/div[2]/div/div[2]/div/span[3]"))).click()

另请注意：

Facebook 可能会在用户上传图像时动态创建新的 XPATH，因此如果 CSS_SELECTOR 是静态的位置按钮，则应该使用该方法而不是 XPATH

尝试使用 javascriptExecutor

shareButton= driver.find_element_by_xpath("//your/xpath/here//")
driver.execute_script("arguments[0].click();", shareButton)
