Just for fun and for completeness…

I haven't checked cross-browser compatibility (only tried in Chrome), and it has some quirks:

var input = "font-weight:bold; color: blue; margin: 0 15px";

var e = document.createElement("div");
e.setAttribute("style", input);

var output = {};

for (var i = 0; i < e.style.length; i++) {
  var name = e.style[i];
  var value = e.style.getPropertyValue(name);
  output[name] = value;
}

The quirk is that even though we passed in a single margin declaration, we get an object like

{
  color: "blue",
  font-weight: "bold",
  margin-bottom: "0px",
  margin-left: "15px",
  margin-right: "15px",
  margin-top: "0px",
}

This might be a good or a bad thing depending on what you're after.
