如何将此图片库中的大图更改为缩略图?我似乎不能使它工作。我需要将缩略图的src属性转换为大src属性的值。

        </div>
        <script>
        function thumbFunc(a)
        {
        document.getElementById("big").setAttribute(src, a);
        }
        </script>
</body>
</html>

首先，改变内联on-click函数的调用方式:

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

，所以你不需要再输入图像路径:

onclick="thumbFunc(this.src)"

然后，修改你的javascript:

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

到此(如果您喜欢更简单的方式):

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

或者如果您仍然想坚持使用setAttribute方法，不要忘记将属性(src)与"符号括起来:

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