我想获取该属性的值。我试图通过

获取alt属性

jQuery('#galleryalbum img').attr('alt'); 但我不能得到价值

＆＃13;

jQuery(function() {
  jQuery(document).ready(function() {
    // jQuery('#galleryalbum img').each(function(){
    title = jQuery('#galleryalbum img').attr('alt');
    console.log(title);
    //});    
  });

<div id="galleryalbum" style="height: 100px; width: auto; position: relative;">

  </div>
</div>

Answer 1

您的代码工作正常但alt为空。

＆＃13;

alert($('img').attr('alt'));

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<img src="https://i.stack.imgur.com/5OA0z.jpg?s=64&g=1" alt="test">

＆＃13;

Answer 2

在你的HTML中，alt是空的，我相信你期待看到标题中的内容。如果你在alt =“这里有一些内容”中给出一些内容，你将在控制台中得到结果。如果要查看title属性中的文本，请使用

 jQuery(function() {
       jQuery(document).ready(function() {
       // jQuery('#galleryalbum img').each(function(){
             title = jQuery('#galleryalbum img').attr('title');
             console.log(title);
       // });    
       });
    });
