在这个小程序中，需要把images文件夹下图片的命名设置为有顺序的，1、2、3……
复制代码 代码如下:
<script type="text/javascript">
var imgnumb = 1;
function imgfor() {
imgnumb++;
document.getElementById('img1').setAttribute('src', 'images/' + imgnumb + '.jpg');
if (imgnumb == 5) { //共5张图片
imgnumb = 0;
}
}
var clearid;
function clearfun() {
clearInterval(clearid);
}
clearid=setInterval(imgfor, 500);
</script>
</head>
<body>
<img alt="" id="img1" src="images/1.jpg" width="500px" height="500px" />
<input type="button" value="结束执行" />
</body>
var imgnumb = 1;
function imgfor() {
imgnumb++;
document.getElementById('img1').setAttribute('src', 'images/' + imgnumb + '.jpg');
if (imgnumb == 5) {
imgnumb = 0;
}
}
var clearid;
function clearfun() {
clearInterval(clearid);
}
clearid=setInterval(imgfor, 500);
</script>
</head>
<body>
<img alt="" id="img1" src="images/1.jpg" width="500px" height="500px" />
<input type="button" value="结束执行" />
</body>
