Javascript 以编程方式设置变换原点的正确方法

这是以编程方式跨浏览器设置变换原点的正确方法吗？谢谢

var s = element.style;

s.webkitTransformOrigin = transform;
   s.MozTransformOrigin = transform;      //cap first letter
    s.msTransformOrigin = transform;
     s.OTransformOrigin = transform;      //cap first letter
      s.transformOrigin = transform;

所以我决定用Modernizer这样做：

transform: null,
transformOrigin: null,

initCss: function() {
    this.transform = Modernizr.prefixed('transform');
    this.transformOrigin = Modernizr.prefixed('transformOrigin');
},

setTransform: function(element, transform) {
    if (this.transform) {
        element.style[this.transform] = transform;
    }
    else {                                //fallback just in case
        var s = element.style;

        s.webkitTransform = transform;
        s.MozTransform = transform;       //cap first letter
        s.msTransform = transform;
        s.OTransform = transform;         //cap first letter
        s.transform = transform;
    }
},
