File inputs are read only. Use a v-on:change listener instead.

Thank you for your question! In Vue.js, file inputs are indeed read-only by default. To handle file input changes, you can use the `v-on:change` event listener. This event is triggered when the user selects a file. You can then access the selected file(s) and perform any necessary operations.
Here's an example of how you can use the `v-on:change` event listener with a file input:
```html
<template>
<div>
<input type="file" @change="handleFileChange" />
</div>
</template>
<script>
export default {
methods: {
handleFileChange(event) {
const selectedFiles = event.target.files;
// Perform operations with the selected file(s)
// For example, you can read the file content or upload it to a server
// Access the first selected file
const firstFile = selectedFiles[0];
console.log('Selected file:', firstFile);
}
}
}
</script>
```
In this example, the `handleFileChange` method is called when the file input's value changes. Inside this method, you can access the `event.target.files` property to get the selected file(s). You can then perform any necessary operations with the file(s).
I hope this helps! Let me know if you have any further questions.
