為什么前面那段script無法實現作用呢？
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<link rel="stylesheet" href="rabbit.css">
<script type="text/javascript">
var imgUrl='rabbit-big.png';
var positions=['0 -854','-174 -852','-349 -852','-524 -852','-698 -852','-873 -848'];
var ele=document.getElementById("rabbit");
animation(ele,position,imgUrl);
function animation(ele,positions,imgUrl){
? ?ele.style.backgroundImage='url(' + imgUrl + ')';
? ?ele.style.backgroundRepeat='no-repeat';
? ?
? ?var index=0;
? ?
? ?function run(){
??
? var position=position[index].split(' ');
? ele.style.backgroundPosition=position[0]+'px '+position[1]+'px ';
? index++;
??
? if(index>=position.length){
? index=0;
? }
?setTimeout(run,80);
?
? ?}
? ?run();
}
</script>
