問題：如何動態添加ALT或TITLE標記圖像？

Code: 
<div class="country"> 
<img src="Flag.png" title="" alt=""> 
<img src="World.png" title="" alt=""> 
<img src="Man.png" title="" alt=""> 
<img src="Woman.png" title="" alt=""> 
</div> 

Answer 1

$('img').eq(0).attr('alt','Flag').attr('title','Flag') 
 
console.log("alt "+$('img').eq(0).attr('alt'))//setter 
 
console.log("title "+$('img').eq(0).attr('title'))//getter

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> 
 
<div class="country"> 
 
<img src="Flag.png" title="" alt=""> 
 
<img src="World.png" title="" alt=""> 
 
<img src="Man.png" title="" alt=""> 
 
<img src="Woman.png" title="" alt=""> 
 
</div>

使用.attr()
