我创建了一个动画循环。一旦一个动画完成，它就会触发下一个动画，依此类推。似乎当我保持浏览器打开 1-2 分钟时，它开始变慢并消耗越来越多的资源，直到我的浏览器响应缓慢并且动画几乎不再运行。我怎样才能防止这种情况发生？这是我的代码：

<!DOCTYPE html>
<html>
<head>
<title></title>
<style type="text/css">
html, body {
    margin: 0;
}
.shared {
    position: absolute;
    opacity: 0;
}
img#article-02 {
    top: 0;
    left: 0;
    width: 205px;
    height: 205px;
}
img#article-03 {
    top: 227px;
    left: 0;
    width: 205px;
    height: 205px;
}
img#article-04 {
    top: 318px;
    left: 227px;
    width: 431px;
    height: 114px;
}
@-webkit-keyframes article2 {
0%   {opacity: 0;}
10%  {opacity: 1;}
60%  {opacity: 1;}
70%  {opacity: 0;}
100% {opacity: 0;}
}
@-webkit-keyframes article3 {
0%   {opacity: 0;}
20%  {opacity: 1;}
70%  {opacity: 1;}
80%  {opacity: 0;}
100% {opacity: 0;}
}
@-webkit-keyframes article4 {
0%   {opacity: 0;}
30%  {opacity: 1;}
80%  {opacity: 1;}
90%  {opacity: 0;}
100% {opacity: 0;}
}
</style>
<script type="text/javascript" src="jquery-1.7.2.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
    animArticle02();
});

function animArticle02() {
    $("#article-02").css('-webkit-animation', 'article2 2s linear');
    var $element = $("#article-02").bind("webkitAnimationEnd", function(){
        this.style.webkitAnimationName = "";
        animArticle03();
    });
}
function animArticle03() {
    $("#article-03").css('-webkit-animation', 'article3 2s linear');
    var $element = $("#article-03").bind("webkitAnimationEnd", function(){
        this.style.webkitAnimationName = "";
        animArticle04();
    });
}
function animArticle04() {
    $("#article-04").css('-webkit-animation', 'article4 2s linear');
    var $element = $("#article-04").bind("webkitAnimationEnd", function(){
        this.style.webkitAnimationName = "";
        animArticle02();
    });
}
</script>
</head>
<body>
<img id="article-02" class="shared" src="article-02.png" alt="" />
<img id="article-03" class="shared" src="article-03.png" alt="" />
<img id="article-04" class="shared" src="article-04.png" alt="" />
</body>
</html>

它可能与重复的绑定和 jQuery 调用有关。试试这个脚本：

//shorthand .ready()
$(function() {

    //cache elements
    var ar2 = $("#article-02"),
        ar3 = $("#article-03"),
        ar4 = $("#article-04");

    //bind once
    ar2.bind("webkitAnimationEnd", function() {
        this.style.webkitAnimationName = "";
        animArticle03();
    });
    ar3.bind("webkitAnimationEnd", function() {
        this.style.webkitAnimationName = "";
        animArticle04();
    });
    ar4.bind("webkitAnimationEnd", function() {
        this.style.webkitAnimationName = "";
        animArticle02();
    });

    //animate
    function animArticle02() {
        ar2.css('-webkit-animation', 'article2 2s linear');
    }

    function animArticle03() {
        ar3.css('-webkit-animation', 'article3 2s linear');
    }

    function animArticle04() {
        ar4.css('-webkit-animation', 'article4 2s linear');
    }

    animArticle02();
});​

"transition" 和 "-webkit-keyframes" 都会导致 Chrome 上的内存泄漏。
