Javascript 在我的例子中，如何检查css动画是否完成？

我正在尝试检测我的css动画是否在我的应用程序中结束

我有如下的东西

  animation.prototype.nextStage = function(){
       this.ball.show().addClass('stage' + this.stage); //start the animation
       this.ball.on('animationend mozanimationend webkitAnimationEnd oAnimationEnd msanimationend',function(){
            //when animation is ended, do something for animation item itself….
        })
    }

   animation.prototype.isEnded = function(){
     // now sure how to check if the animation is ended outside of the animation obj.
    }


 function main(){
    this.ball = new animation ();
 }

main.prototype.checkAnimation = function(){
    this.ball.nextStage();
    if(this.ball.isEnded){
      //do stuff for something that is not part of animation items..
    }
}

我不知道如何检查我的球动画是否在我的主对象中完成。有人能帮我吗？非常感谢

这样，您可以在每次调用

nextStage

时添加新的事件处理程序

最好使用以下内容：

function animation(ball, completeCallback) {
    var self = this;
    this.isEnded = false;
    this.ball = ball;
    this.ball.on('animationend mozanimationend webkitAnimationEnd oAnimationEnd msanimationend', function () {
        self.isEnded = true;
        if (typeof completeCallback === 'function') {
            completeCallback();
        } 
    });
}
animation.prototype.nextStage = function () {
    this.ball.show().addClass('stage' + this.stage); //start the animation
    this.isEnded = false;
}


function main() {
    this.ball = new animation(DOM_ELEMENT, this.completeCallback);
}

main.prototype.completeCallback = function () {
   alert('ANIMATION IS DONE');
};

main.prototype.checkAnimation = function () {
    if (this.ball.isEnded) {
        //do stuff for something that is not part of animation items..
    }
}

调用

this.ball.nextStage（）当您想要设置动画时。

调用
this.ball.nextStage（）当你想制作动画时。
如果你在做一些异步的事情，你可以使用承诺或回调。这样传递回调可能对您有用：

animation.prototype.nextStage = function (callback) {
    this.ball.show().addClass('stage' + this.stage); //start the animation
    this.ball.on('animationend mozanimationend webkitAnimationEnd oAnimationEnd msanimationend', function () {
        if (callback) callback();
    })
}    

main.prototype.checkAnimation = function () {
    this.ball.nextStage(function () {
        //do stuff for something that is not part of animation items..
    });
}

这里有一个可能的承诺实现：

animation.prototype.nextStage = function () {
    var def = $.Deferred();
    this.ball.show().addClass('stage' + this.stage); //start the animation
    this.ball.on('animationend mozanimationend webkitAnimationEnd oAnimationEnd msanimationend', function () {
        def.resolve(true);
    });
    return def.promise();
}

main.prototype.checkAnimation = function () {
    var promise = this.ball.nextStage();

    promise.done(function () {
        //do stuff for something that is not part of animation items..
    });
}

您是否尝试过承诺或回调？动画完成后执行

。也许可以给它起个更有意义的名字。谢谢你的提示，但是，动画需要时间来播放，而这个.ball.isEnded总是为false。要达到self.isEnded=true，我不知道如何设置它+1您可以添加回调。请查看我答案中的更改。感谢您的提示，但是，动画需要时间来播放，而this.ball.isEnded始终为false。要达到self.isEnded=true，我不知道如何设置它+1您可以添加回调。请查看我答案中的更改。感谢您的提示，但是，动画需要时间来播放，而this.ball.isEnded始终为false。要达到self.isEnded=true，我不知道如何设置它+1您可以添加回调。请查看我答案中的更改。感谢您的提示，但是，动画需要时间来播放，而this.ball.isEnded始终为false。要达到self.isEnded=true，我不知道如何设置它+1您可以添加回调。看看我答案中的变化。
