我遵循了一个简单的 javascript 幻灯片教程。它运行得很完美，我们在内部将 javascript 放入了 html 文档中。当我尝试将代码链接到我制作的页面并尝试单击下一个或上一个时，该页面只会重新加载第一张图像。有什么想法吗？
这是我的 html 代码
<!DOCTYPE html>
<html>
<head>
<link type="text/css" rel="stylesheet" href="stylesheetmusic.css"/>
<script type="text/javascript" src="slidescript.js"></script>
<title>New York Knicks</title>

<body>
<div id="header">

<div id="footer">

</div>
</body>
</html>
这是我的 JavaScript 文件
<script type="text/javascript">
var Image = new Array("tom.jpg", "mark.jpg", "travis.jpg");
var Image_Number = 0;
var Image_Length = Image.length - 1;
function change_image(num){
Image_Number = Image_Number + num;
if (Image_Number > Image_Length){
Image_Number = 0;
}
if (Image_Number < 0){
Image_Number = Image_Length;
}
document.slideshow.src= Image[Image_Number];
return false;
}
</script>
最佳答案
您需要从 JavaScript 文件中删除脚本标记。 javascript 文件 (slidescript.js) 的完整文本应为:
var Image = new Array("tom.jpg", "mark.jpg", "travis.jpg");
var Image_Number = 0;
var Image_Length = Image.length - 1;
function change_image(num){
Image_Number = Image_Number + num;
if (Image_Number > Image_Length){
Image_Number = 0;
}
if (Image_Number < 0){
Image_Number = Image_Length;
}
document.slideshow.src= Image[Image_Number];
return false;
}
