An issue arises when attempting to utilize v-model with a file input

Is there a way to reset a file input field in Vue.js after uploading a file? I attempted to set the v-model value to null, but encountered an error message that said:

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

This is my current code snippet:

<input id="fileupload" type="file" v-model="file" multiple v-on:change="uploadFile" ref="fileInput" />

If anyone knows how to clear the file input after uploading a file so it can be uploaded again multiple times without interruption in Vue.js, please share your insights. Thank you!

Ensure your

v-on:change="uploadFile"

function has a success callback for handling file uploads.

To improve your code, consider the following steps:

Enclose your input field within a form element and assign a ref attribute to the form:

<form ref="myFileInputForm">
      <input id="fileupload" type="file" v-model="file" multiple v-on:change="uploadFile" ref="fileInput" />
 </form>

Add this line in your success callback function uploadFile:
```
this.$refs.myFileInputForm.reset();
```

File selections can only be read, not modified. To prevent binding on the element, delete v-model="file"
