# HTML custom data attributes
**Rudolf Farkas**
explain the relations between `data-audio-file` and `button.dataset.audioFile`
**Tabnine Claude 3.5 Sonnet**
Certainly! The relationship between `data-audio-file` and `button.dataset.audioFile` is a key part of how HTML5 data attributes work with JavaScript. Let's break it down:
1. HTML Data Attribute:
In the HTML (or in this case, the Astro component template), we have:
```astro
```
Here, `data-audio-file` is a custom data attribute. The `data-` prefix is special; it allows you to store custom data on HTML elements.
2. JavaScript Dataset API:
In the JavaScript part, we access this data using the `dataset` property:
```javascript
const audioFile = button.dataset.audioFile;
```
3. How They Relate:
- When you create a data attribute like `data-audio-file` in HTML, it becomes available in JavaScript through the `dataset` object.
- The naming convention is transformed:
- The `data-` prefix is removed.
- Any hyphens are converted to camelCase.
So, `data-audio-file` in HTML becomes `audioFile` in `dataset`.
4. Value Assignment:
- In the Astro component, you're setting the value dynamically:
```astro
data-audio-file={audioFile}
```
- This means each button will have its `data-audio-file` attribute set to the corresponding `audioFile` value from your `audioFiles` array.
5. Accessing in JavaScript:
- When you use `button.dataset.audioFile` in your script, you're retrieving the value that was set in the HTML.
- This allows you to access the specific audio file path for each button when it's clicked.
In summary, `data-audio-file` in the HTML/Astro template is how you store the data, and `button.dataset.audioFile` in JavaScript is how you retrieve that data. This mechanism allows you to associate custom data with HTML elements and easily access it in your JavaScript code, creating a bridge between your markup and your script.
