You can use the getComputedStyle function, which is supported by most major browsers - IE9,IE10,Chrome,FF. I have not found a way to do this in IE8 though.

var attrContent = getComputedStyle(this,':after').content;
var attrWidth = getComputedStyle(this,':after').width;

If you find this function is undefined try window.getComputedStyle instead.
