我的图像宽度为4096px,屏幕宽度为960px。我必须创建连续的水运动。为此我使用32个图像的精灵我的代码如下
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Lets learn grammer</title>
<script language="javascript" type="text/javascript" src="jquery.js"></script>
<script>
function moveBack(){
var i=0;
setInterval(function(){
if(i<23){
i++;
$('#bck').css('background-position',((i)*-130));
}else{
//for(var j=0; j<=4;j++){
$('#bck').css('background-position',0);
//}
i=0;
}
}, 50);
}
</script>
<style type="text/css">
#bck{
position:absolute;
width:960px;
height:540px;
background-image:url("water.png");
background-repeat:repeat-y;
top:0px;
left:0px;
border:1px solid red;
}
</style>
</head>
<body onload="moveBack()">
<div id="bck"></div>
</body>
此代码将整个精灵移动到结束点后停止。但我想继续运动,直到我停止执行。
谢谢
