Getting attribute from class using javascript?

Question

如何从以下标记获取属性“ src”：

<div class="entry"><img width="300" height="200" src="http://domain/myimg.jpg" alt="text" /></div>

Answer 1

I would recommend using an ID for the 'entry' element (or directly on the image element) instead of a class.

If that's not possible use this:

var x = document.querySelector('.entry img');
alert('src: ' + x.getAttribute('src'));
