如果你需要改变动画播放速度,
比如每5秒换一张图片
改变setTimeout('imgturn('' +numb+ '')', 1000)中的1000为5000
＜html>
＜head>
＜title>＜/title>
＜script language='JavaScript'>
＜!--
//请先准备几张JPG图片格式的,名字是demo1.jpg,demo2.jpg,demo3.jpg
if (document.images) {
demo1 = new Image();
demo1.src = '../../images/demo1.jpg';
demo2 = new Image();
demo2.src = '../../images/demo2.jpg';
demo3 = new Image();
demo3.src = '../../images/demo3.jpg';
}
function timeimgs(numb) {
thetimer = setTimeout('imgturn('' +numb+ '')', 1000);
}
function imgturn(numb) {
if (document.images) {
if (numb == '3') {
document['demo'].src = eval('demo3.src');
timeimgs('1');
}
else { document['demo'].src = eval('demo' + numb + '.src');
timeimgs(numb = ++numb);
}
}
}
// -->
＜/script>
＜/head>
＜body onload='timeimgs('2');'>
＜img src='../../images/demo1.jpg' name='demo' width='100' height='100' alt='demo'> |
