Python Selenium - 点击基于样式属性或子元素包含文本的css元素？ Twitter关注

Question

为了消除任何困惑，我的最终目标是点击所有我还没有关注的用户的follow按钮。在

你好，我已经挂了几个小时了，谢谢你的意见。我试图单击包含文本“Following”的页面上的所有按钮，以避免单击我已经关注的用户的按钮，因为标记的性质以及单击按钮可以跟踪和取消跟踪用户。在

旁注：“user actions follow button js follow btn follow button”的第一个button同级元素将显示属性从显示：无到显示：阻止用户尚未被跟踪。在

我该如何完成这项任务？当我试图在一个错误的项目点击。在

html_list = driver.find_element_by_css_selector(".Grid--withGutter")
items = html_list.find_elements_by_css_selector(".follow-text")

for item in items:
item.click()

到目前为止已经成功了，但是没有区别于已经关注的用户，所以它不关注我已经关注的用户。在

这是一个单键的例子，页面中会包含几十个按钮。在

<span class="user-actions-follow-button js-follow-btn follow-button">
  <button type="button" class="EdgeButton EdgeButton--secondary EdgeButton--small button-text follow-text">
    <span aria-hidden="true">Follow</span>
    <span class="u-hiddenVisually">Follow 
      <span class="username u-dir" dir="ltr">@<b>jefken11</b></span>

如果您要做的是单击包含“Following X”的所有可见的BUTTON，那么这些都有一个CSS类following-text。为什么不用这个？在

items = driver.find_elements_by_css_selector("button.following-text")
visible_items = [item for item in items if item.is_displayed()]
for item in visible_items
    item.click()
