你必须知道的【闭包】陷阱和案例(6)

            obj.printName = function () {

真实案例：
// create and populate the screen with random daisies:
for(var i = 0; i < 100; i++){
    bitmap = new Bitmap(image);
    container.addChild(bitmap);
    bitmap.x = canvas.width * Math.random()|0;
    bitmap.y = canvas.height * Math.random()|0;
    bitmap.rotation = 360 * Math.random()|0;
    bitmap.regX = bitmap.image.width/2|0;
    bitmap.regY = bitmap.image.height/2|0;
    bitmap.scaleX = bitmap.scaleY = bitmap.scale = Math.random()*0.4+0.6;
    bitmap.name = "bmp_"+i;
    // wrapper function to provide scope for the event handlers:
    (function(target) {
        bitmap.onPress = function(evt) {
            // bump the target in front of it's siblings:
            container.addChild(target);
            var offset = {x:target.x-evt.stageX, y:target.y-evt.stageY};
            // add a handler to the event object's onMouseMove callback
            // this will be active until the user releases the mouse button:
            evt.onMouseMove = function(ev) {
                target.x = ev.stageX+offset.x;
                target.y = ev.stageY+offset.y;
                // indicate that the stage should be updated on the next tick:
                update = true;
            }
        }
        bitmap.onMouseOver = function() {
