如何使用鼠标悬停（或悬停）以便在 go 在不同的文本上显示不同的图像？ JAVASCRIPT

Question

I'm currently doing CS50 and I need to write a little html page inserting interactive elements from Javascript.I'm a total beginner with this language and I'm trying to find out how to display an image when I hover on a text. Apparently there's almost zero topic about this on internet, I've only found this,which does work but only with the first image.The reason is because the "id" is the same for all the urls,I get that,but how can I modify the code so that it can work for all the different texts/pictures?I kind of get the whole picture because I know Python but html and Js are brand new to me.Any help would be appreciated,thanks

 <div>
 <table>
   <tr>
     <th>Best Albums</th>
     <th>Year</th>
       </tr>
       <tr>
         <td><img class="hidden" id='image' src="https://cdn.mos.cms.futurecdn.net/2Lm375yVwwGyAHfNFP2HU6-970-80.jpg.webp"/> <span>Spreading the disease</span></td>

ids have to be unique. So you need to find a different way to select the element. Since it is a sibling, you can use prev() to select it.

 $(document).ready(function() { $('span').hover(function() { $(this).addClass('underline').prev("img").show(); }, function() { $(this).removeClass('underline').prev("img").hide(); }); });

 .hidden { display: none; height: 100px; }
