Bouncing Ball不会停止反弹
每次我这样做时,都会留下一个非常烦人的问题 - 球只会在底部稍微反弹一点。
请在下面找到我的jsfiddle代码链接

(function(){
var bounceBall = {} || bounceBall;
bounceBall = {
container: {
obj : null,
width : 0,
height : 0,
interval : 0
},
ball : {
obj : null,
top : 0,
left : 0,
height : 0,
width : 0,
maxWidth : 0,
maxHeight : 0,
dx : 10,
dy : 30,
stopBall : false,
moveRight : true,
moveDown : true,
counter : 0
},
init: function(){
console.log("BounceBall Init");
var self = this;
var myContainer
if(document.getElementById('container'))
myContainer = document.getElementById('container');
myContainer.addEventListener('click', self.handleClick, false);
self.setBall(myContainer);
self.ball.width = self.ball.obj.clientWidth;
self.ball.height = self.ball.obj.clientHeight;
},
setBall : function(myContainer){
var ballDiv = document.createElement("div");
this.container.obj = myContainer;
this.container.width = myContainer.clientWidth;
this.container.height =myContainer.clientHeight;
ballDiv.className= "ball";
this.ball.obj = ballDiv;
myContainer.appendChild(ballDiv);
},
handleClick : function(event){
console.log(bounceBall.container.height + " " + event.y);
bounceBall.ball.top = bounceBall.container.height;
bounceBall.ball.maxHeight = event.y;
bounceBall.ball.maxWidth = event.x;
bounceBall.ball.obj.style.top = bounceBall.ball.maxHeight + 'px';
bounceBall.ball.obj.style.left = bounceBall.ball.maxWidth + 'px';
bounceBall.container.interval = setInterval(function(){bounceBall.move(); },100);
},
move : function(){
if (this.ball.top >= this.ball.maxHeight){
this.ball.moveDown = false;
}
if (this.ball.top <= 0){
this.ball.moveDown = true;
this.ball.maxHeight = this.ball.maxHeight -20;
}
if (this.ball.moveDown){
this.ball.top = this.ball.top + this.ball.dy;
} else {
this.ball.top = this.ball.top - this.ball.dy;
}
this.ball.obj.style.top = this.container.height - this.ball.top + 'px';
}
};
bounceBall.init();
})();
我很感激若有人能指出我的错误。
var bounceBall = {} || bounceBall;
。应该是var bounceBall = bounceBall || {};
。此外,在这之后,您只需通过重新声明变量来覆盖它:bounceBall = {...}
