Question

我创造了一个动画循环。一旦完成了一个动画循环,它就会触发下一个动画循环。当我保持浏览器开放1-2分钟时,它开始减速并食用越来越多的资源,直到我的兄弟会回答粗糙的动画,动画几乎不再运行。我怎么能防止这种情况发生呢?这里的代码是:

<!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>

Answer 1

它可能和重复的绑定和jQuery 调用有关。尝试此脚本 :

//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();
});

“过渡”和“网基核心框架”都会导致铬的记忆泄漏。
