我已经创建了一组问题和答案，每个问题旁边是一个img，每当有人点击一个问题时，我会尝试切换该图像的src。到目前为止，因为问题存储在nodelist中，我设法让图像切换，但它切换了所有的图像，我只想让我点击的问题切换存储在里面的图像。

We'll pass your e-mail address and mobile number (if provided) to Hermes or DPD and they'll provide you with information about your delivery by e-mail or text message the evening before. <br> Please note deliveries outside of the UK can take anything up to 10 days. Follow your order using the tracking link in your despatch email to check if any delivery attempt has been made.",
