我如何才能将此图片库更改为缩略图?我似乎无法让它发挥作用。我需要将缩略图的src属性转换为big src属性值的值。

<html>
<head>
    <title>title</title>
    <link rel="stylesheet" type="text/css" href="CSSChloe.css">

首先,更改内联点击时调用函数的方式:

onclick="thumbFunc('test2.png');"

这样,所以你不必再次放置图像路径了:

onclick="thumbFunc(this.src)"

然后,更改您的javascript:

document.getElementById("big").setAttribute(src, a);

到此(如果您更喜欢简单的方式):

document.getElementById("big").src = a;

或者如果您仍想坚持使用setAttribute方法,请不要忘记使用"符号将属性(src)括起来:

document.getElementById("big").setAttribute("src", a);
