Output CSS Markup to a string using Javascript

I'm wondering if anyone has had experience trying to output the css markup of a given element using javascript.

Note: Using Webkit only.

For example:

HTML:

<div id="css"></div>

Styling:

#css {
    background: #F1F3F5;
    border: 1px solid #B4BFC9;

    -moz-box-shadow: 0px 1px rgba(0, 0, 0, 0.3);
    -webkit-box-shadow: 0px 1px rgba(0, 0, 0, 0.3);
    box-shadow: 0px 1px rgba(0, 0, 0, 0.3);
}

nifty jQuery plugin? :)

alert($('#css').getCSS());

Alert

#css {
    background: #F1F3F5;
    border: 1px solid #B4BFC9;

    -moz-box-shadow: 0px 1px rgba(0, 0, 0, 0开发者_高级运维.3);
    -webkit-box-shadow: 0px 1px rgba(0, 0, 0, 0.3);
    box-shadow: 0px 1px rgba(0, 0, 0, 0.3);
}

function css(a){
    var sheets = document.styleSheets, o = {};
    for(var i in sheets) {
        var rules = sheets[i].rules || sheets[i].cssRules;
        for(var r in rules) {
            if(a.is(rules[r].selectorText)) {
                o = $.extend(o, css2json(rules[r].style), css2json(a.attr('style')));
            }
        }
    }
    return o;
}

function css2json(css){
        var s = {};
        if(!css) return s;
        if(css instanceof CSSStyleDeclaration) {
            for(var i in css) {
                if((css[i]).toLowerCase) {
                    s[(css[i]).toLowerCase()] = (css[css[i]]);
                }
            }
        } else if(typeof css == "string") {
            css = css.split("; ");          
            for (var i in css) {
                var l = css[i].split(": ");
                s[l[0].toLowerCase()] = (l[1]);
            };
        }
        return s;
    }

Usage:

var style = css($("#elementToGetAllCSS"));
$("#elementToPutStyleInto").css(style);
