Question

我需要在Python中使用selenium webdriver从下拉列表中选择一个元素。为此，我查看了有用的帖子，例如Selecting a value from a drop-down option using selenium python和 https://sqa.stackexchange.com/questions/12029/how-do-i-work-with-dropdowns-in-selenium-webdriver?lq=1。

我正在谈论的元素显示在下一个块中：

<div id="dayTab" style="height:20px" class="ui-tabs-panel ui-widget-content ui-corner-bottom ui-tabs-hide">
 <select class="input-small input-thin">
   <option value="2010">2010</option>
   <option value="2011">2011</option>
   <option value="2012">2012</option>
   <option value="2013">2013</option>
   <option value="2014">2014</option>
   <option value="2015">2015</option>
 </select>
</div>

我尝试了Select()：

yearselect = Select(browser.find_element_by_css_selector("select.input-small.input-thin"))
yearselect.select_by_value("2010")

虽然它找到了元素（它所做的），然后我得到第二行发生的以下错误：

Traceback (most recent call last):
File "C:\Users\elek2\workspace\webdriving\src\gotonch.py", line 119, in <module>

我不确定为什么会发生这种情况，但我也尝试使用Click()代替“打开”下拉列表

yearselect =browser.find_element_by_css_selector("select.input-small.input-thin").click()
yearselect.select_by_value("2010")

并且元素是可见的但是我得到了这个：

Traceback (most recent call last):

yearselect = browser.find_element_by_css_selector("select.input-small.input-thin").click()

如果我能够找到下拉列表并选择它，为什么元素仍然不可见？

编辑：

在LINGS评论之后，我意识到不仅有一个带有我用过的css名称的元素。

我在上面的块之后但是在那之前引用了另一个块而不是div id="dayTab"...是div id="monthTab"...这显然是不可见的。我如何参考我想要的标签，没有ID。

Answer 1

毕竟这很简单，我取代了最初的：

rate

用这个：

yearselect = Select(browser.find_element_by_css_selector("select.input-small.input-thin"))
yearselect.select_by_value("2010")

只需找到正确的CSS（或XPath）即可。诸如XPath Helper之类的Chrome加载项可能有助于此。有关CSS选择器的其他提示，您可以在here中找到。很高兴万一我帮助其他用户避免这种恼人的错误。
