我们使用CSS3之transform/-webkit-keyframes实现动画时，动画结束状态不会自动保持。
代码如下：
<!DOCTYPE html>
<html lang="zh-cn" class="no-js">
<head>
<meta http-equiv="Content-Type">
<meta content="text/html; charset=utf-8">
<meta charset="utf-8">
<title>沪江网</title>
<meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no">
<meta name="format-detection" content="telephone=no">
<meta name="format-detection" content="email=no">
<meta name="author" content="wechat:femvc_com">
<style>
.aa {position:absolute;left:0px;top:0px;z-index:50; }
@-webkit-keyframes 'dddin' {
0% {
left: 0px
}
100% {
left: 200px
}
}
.dddin {
-webkit-animation-name: "dddin";
-webkit-animation-duration: 0.3s;
-webkit-animation-timing-function: ease;
-webkit-animation-iteration-count: 1;
}
</style>
</head>
<body>
<button class="aa" onclick="this.className+=' dddin'">button</button>
</body>
</html>
需要将动画结束状态放到class中。
代码如下：
<!DOCTYPE html>
<html lang="zh-cn" class="no-js">
<head>
<meta http-equiv="Content-Type">
<meta content="text/html; charset=utf-8">
<meta charset="utf-8">
<title>沪江网</title>
<meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no">
<meta name="format-detection" content="telephone=no">
<meta name="format-detection" content="email=no">
<meta name="author" content="wechat:femvc_com">
<style>
.aa {position:absolute;left:0px;top:0px;z-index:50; }
@-webkit-keyframes 'dddin' {
0% {
left: 0px
}
100% {
left: 200px
}
}
.dddin {
left: 200px;
-webkit-animation-name: "dddin";
-webkit-animation-duration: 0.3s;
-webkit-animation-timing-function: ease;
-webkit-animation-iteration-count: 1;
}
</style>
</head>
<body>
<button class="aa" onclick="this.className+=' dddin'">button</button>
</body>
</html>
