I want to convert it to javascript function for using on old browser. I know there are many easing function out there, but I just want to know how to convert. Is it possible?

You can use the jQuery Bez plugin for Cubic Bezier Easings in jQuery:

Demo: http://jsfiddle.net/SO_AMK/sbZ7a/

jQuery:

$("#box").click(function() {
    $(this).animate({
        "margin-left": 200
    }, 2000, $.bez([0.685, 0.595, 0.020, 0.720]));
});

// Take the Ceaser output and put the values in, in order, like above. i.e. cubic-bezier(0.685, 0.595, 0.020, 0.720) would end up as the above value​
