如何使用Python在没有元素的情况下单击侧栏菜单

python python-3.x selenium

如何使用Python在没有元素的情况下单击侧栏菜单,python,python-3.x,selenium,Python,Python 3.x,Selenium,在一个网站中有一个侧边栏菜单，我想点击其中的一个元素，我将向您解释：侧边栏菜单： Mobiles - iOS - Android Laptops TVs 我想点击手机来显示手机的操作系统选项，但在页面源代码中我并没有找到任何ID或类…等与此侧边栏菜单相关的内容，我只有java脚本代码，当我打开手机firefox inspect时，我找到了这些代码 <tr class="h1" style="cursor:pointer" onclick="javascript:ope

在一个网站中有一个侧边栏菜单，我想点击其中的一个元素，我将向您解释：

侧边栏菜单：

 Mobiles
   - iOS
   - Android
 Laptops
 TVs

我想点击手机来显示手机的操作系统选项，但在页面源代码中我并没有找到任何ID或类…等与此侧边栏菜单相关的内容，我只有java脚本代码，当我打开手机firefox inspect时，我找到了这些代码

<tr class="h1" style="cursor:pointer" onclick="javascript:openLink('getpage.gch?pid=1002&amp;nextpage=app_ddns_conf_t.gch')" onmouseover="altMenuClass(this,true)" onmouseout="altMenuClass(this,false)"><td class="add">&nbsp;</td><td class="mid" id="nothing">Mobiles</td></tr>

并尝试了selenium的所有属性，比如（按名称、id、文本、链接等查找元素），还尝试了使用鼠标悬停，但我只得到了这样一个错误

我的项目因为缺少这一步而停止了，我能做什么呢？我等了太多时间才得到stack overflow的许可来问这个问题，如果你没有回答我，我会等两天再问
