所以我只在我的JSON数据中添加了两个URL，它们都与一首歌曲相关。
现在，前两个图像的歌曲不同，而其他图像完全没有歌曲。
我想从所有div中获取选定的索引，以便可以使用类似songDetails[selectedIndex].Song
但是我不知道如何获得点击的选定索引。
那我该如何开始播放与单击的项目相对应的歌曲？

答案 0 :(得分：0)
您必须定义自己的索引，并根据索引选择歌曲的编号
function playAudio(songDetails, self) {
let index = [...self.parentElement.children].indexOf(self)
let song = new Audio(songDetails[index].Song);
您的点击事件也应该在您的div上
<div class="image-box" onclick="playAudio(imageData, this);">

我更新了您的Option Explicit
Dim h as Long, i as Long, l as Long, j as Long, k as Long, lr as Long
Dim x as Integer
Sub IAR_macro()
On Error GoTo Canceled
i = (Range("B1").End(xlDown).Row) - 1
Sheets(x).Activate
Do While l < (i - l)
和generateTemplate函数。请参阅底部的代码段。
在您的playAudio函数中，我添加了第二个参数playAudio。在您的clickedElement中，您已经传递了参数generateTemplate。 this在这种情况下表示在其上设置onclick的元素。
我还向您的this函数生成的data-song="${imageData.Song}"元素中添加了img。
因此，在generateTemplate函数中，我们收到了单击的playAudio元素。通过调用img，我们检索在clickedElement.dataset.song元素上声明的data-song属性。这样，您就知道要播放什么歌曲。
请注意，当您的图片部分的JSON定义中没有img属性时，它将作为点击的歌曲返回song。因此，在调用undefined之前，您可能必须添加if语句。
let song = new Audio(song);const imageData = [{
