CSS Style property names -- going from the regular version to the JS property camelCase version and vice versa

So you're basically reinventing jQuery.css(). Maybe a look at how jQuery solved the camelCase problem might help: https://github.com/jquery/jquery/blob/master/src/core.js#L600

I was about to ask question about the same thing (and I intended to name it "Translate css names to\from javascript counterparts"). Somehow I ended up writing my own solution.

function cssNameToJsName(name)
{
    var split = name.split("-");
    var output = "";
    for(var i = 0; i < split.length; i++)
    {
        if (i > 0 && split[i].length > 0 && !(i == 1 && split[i] == "ms"))
        {
            split[i] = split[i].substr(0, 1).toUpperCase() + split[i].substr(1);
        }
        output += split[i];
    }
    return output;
}

function jsNameToCssName(name)
{
    return name.replace(/([A-Z])/g, "-$1").toLowerCase();
}
