#container{
  border:solid 1px #ccc;
  margin-top: 10px;

$(function(){

var stage = new Kinetic.Stage({
    container: 'container',
    width: 350,
    height: 350
});
var layer = new Kinetic.Layer();
stage.add(layer);

    var button=new Kinetic.Rect({
        x:30,y:30,width:50,height:35,fill:"green",stroke:"black",strokeWidth:3,
    });
    button.on("mousedown",function(){
        this.setShadowColor("green");
        this.setShadowBlur(20);
        layer.draw();
    });
    button.on("mouseup  mouseleave",function(){
        this.setShadowColor("transparent");
        this.setShadowBlur(0);
        layer.draw();
    });
    layer.add(button);
    layer.draw();

}); // end $(function(){});
