[英]Memory problems with JavaScript + CSS3 animations. How to improve?
I have created a loop of animations.我创建了一个动画循环。 Once one animation is finished, it triggers next one and so on.
一旦一个动画完成,它就会触发下一个动画,依此类推。 Seems that when I keep my browser open for 1-2 minutes, it starts to slow down and eating more and more resources until my broswer answers sloooowly and animations barely run anymore.
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。 How could I prevent this to happen?
我怎样才能防止这种情况发生? Here's my code:
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>
It may have something to do with the repeated bindings and jQuery calls. 它可能与重复绑定和jQuery调用有关。 Try this script:
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。
