<canvas id="imageView" width="560" height="410">您的浏览器版本过低，请更换更高版本的浏览器</canvas>

// 通过画布ID 创建一个 Stage 实例
var stage = new createjs.Stage("imageView");
// 创建一个 Bitmap 实例
var theBitmap = new createjs.Bitmap("imgs/testImg.jpg");
// 设置画布大小等于图片实际大小
stage.canvas.width = theBitmap.image.naturalWidth;
stage.canvas.height = theBitmap.image.naturalHeight;
// 把Bitmap 实例添加到 stage 的显示列表中
stage.addChild(theBitmap);
// 更新 stage 渲染画面
stage.update();

//Create a stage by getting a reference to the canvas
var stage = new createjs.Stage("circleView");
//Create a Shape DisplayObject.
var circle = new createjs.Shape();
circle.graphics.beginFill("DeepSkyBlue").drawCircle(0,0,40);
//Set position of Shape instance.
circle.x = circle.y = 50;
//Add Shape instance to stage display list.
stage.addChild(circle);
//Update stage will render next frame
stage.update();

stage.addEventListener("click",handleClick);function handleClick() {    
// Click happened;
    console.log("The mouse is clicked.");
}
stage.addEventListener("mousedown",handlePress);function handlePress() {    
// A mouse press happened.
    // Listen for mouse move while the mouse is down:
    
    console.log("The mouse is pressed.");
    stage.addEventListener("mousemove",handleMove);
}function handleMove() {    
// Check out the DragAndDrop example in GitHub for more
    console.log("The mouse is moved.");
}

The mouse is pressed.
The mouse is clicked.

// Update stage will render next frame
createjs.Ticker.addEventListener("tick",handleTick);
//添加一个Ticker类帮助避免多次调用update方法
function handleTick() {    
var maxX =  stage.canvas.width - 50;    
var maxY =  stage.canvas.height - 50;    
//Will cause the circle to wrap back
    if(circle.x < maxX && circle.y == 50){        
    // Circle will move 10 units to the right.
        circle.x +=10;
    }else if(circle.x == maxX && circle.y <maxY){
        circle.y +=10;
    }else if(circle.x > 50 && circle.y == maxY){
        circle.x -=10;
    }else if(circle.x<= 50){
        circle.y -=10;
    }
    stage.update();
