selenium里面通過父元素，定位子元素，可以通過二次定位來找到該元素:ele1 = driver.find\_element\_by\_id("yoyo").find\_element\_by\_id("ziyuans")  
但是通過子元素找父元素這種思維之前真沒注意過，實際上selenium里面提供了該方法

<p id="yo" class="hello world">
    <button id="yy_auto" name="heo" >登錄</button>
    <br>
</p>

**雖然用parent方法定位到了父元素，但是無法獲取元素屬性，也不能操作，沒搞懂有啥意義**

另外一個思路，子元素定位父元素，可以通過xpath的語法直接定位：`.//*[@name="heo"]/..`兩個點..就是代表父級元素了
