问题描述
我想在我的网站上制作图片幻灯片，这是我的代码
I wanna make image slideshow on my web, here's my code
<head>
<script type="text/javascript">
var image1 = new Image()
image1.src = "images/pentagg.jpg"
var image2 = new Image()
image2.src = "images/promo.jpg"
</script>
</head>
<body>
<p><img src="images/pentagg.jpg" width="500" height="300" name="slide" /></p>
<script type="text/javascript">
function slideit()
{
var step=1;
document.images.slide.src = eval("image"+step+".src")
if(step<2)
step++
else
step=1
setTimeout("slideit()",2500)
}
slideit()
</script>
</body>
为什么它不起作用？我把想要的图像放在图像文件夹中
Why it's not working? I've put image I want in images folder
推荐答案
- 将var step = 1设为全局变量通过将其置于函数调用上方
- put semicolons
它将如下所示
<head>
<script type="text/javascript">
var image1 = new Image()
image1.src = "images/pentagg.jpg"
var image2 = new Image()
image2.src = "images/promo.jpg"
</script>
</head>
<body>
<p><img src="images/pentagg.jpg" width="500" height="300" name="slide" /></p>
<script type="text/javascript">
var step=1;
function slideit()
{
document.images.slide.src = eval("image"+step+".src");
if(step<2)
step++;
else
step=1;
setTimeout("slideit()",2500);
}
slideit();
</script>
</body>
