Prototype: change attribute

Question

How can I change <img>using a prototype JS library? I managed to get the item, but I could not change the "src":

$('item1').getElementsBySelector('img')

Answer 1

var imgs = $('item1').getElementsBySelector('img');
imgs.each(function(img) {
    img.src = 'newSrc';
});

Answer 2

You can also use the setAttribute function.

var imgs = $('item1').getElementsBySelector('img');
imgs.each(function(img) {
    img.setAttribute('src','newSrc');
    img.setAttribute('width','100px');
});
