如何为div容器中的图像添加“ rel”属性？

Question

I want javascript to add this rel attribute rel="lightbox[1]" to all images from a given container when the page loads...

Is that possible?

<div id="otherimg">
   <p><img src="" alt="" /></p>
   <p><img src="" alt="" /></p>
   <p><img src="" alt="" /></p>
   <p><img src="" alt="" /></p>
</div>

Answer 1

$(function() {
    $('#otherimg img').attr('rel', 'lightbox[1]')
})

Answer 2

this will add to only the img tags inside div with id otherimg

$(function() {

$('div#otherimg img').attr("rel", "lightbox[1]")

})
