I'm using javascript to create an image element like so:

var img = document.createElement('img');

What would I do to give this img a width of 100%?

....

var img = document.createElement('img'); 
img.setAttribute('width', '100%');

Make sure that you attach the img to the body.

document.getElementsByTagName('body')[0].appendChild(img);

You could either specify the width on that image: (taken from others' answer)

var img = document.createElement('img'); 
img.setAttribute('width', '100%');
document.getElementsByTagName("body")[0].appendChild(img);

Or specify a class name and target it in CSS:

JavaScript:

var img = document.createElement('img'); 
img.setAttribute('class', 'wide');
document.getElementsByTagName("body")[0].appendChild(img);

CSS:

img.wide {
    width:100%;
}
