Hey community :) I have a reactivity issue (I think it is about reactivity).
Description
I have FileInput.vue
component. With that component I upload files to project. When the new image is added, the new field is pushing to the form.allImages reactive
array:
@add="addImageField"
addImageField function:
const addImageField = (): void => {
form.allImages.push({ filename: '' });
};
Reactive data:
import type { Images } from '@/types/images.d';
interface Work {
allImages: Images[];
}
const form: Work = reactive({
allImages: [{ filename: '' }],
});
Problem description
When I add 2 images and then try to delete the first one using:
const deleteImageField = (index: number): void => {
form.allImages.splice(index, 1);
};
the first block is removing correctly and the second comes up to its place (it is correct), but now the second image block need to be empty(with clear value to be able to add image to that). The value of the second element in form.allImages
is clear, but the component block is not empty, there remains the image of the block that now is the first element in the array.

Reproduction
https://stackblitz.com/edit/nuxt-starter-qeaeuf?file=app.vue Here is the reproduction.
How to use the reproduction
Click to the Add Image
block and choose any image from your PC and there will be shown static favicon.ico
file just for the example. And there will appear the Delete
button for deleting that image. Above all the blocks you can see the data block for tracking data.
How it is supposed to work
After the delete the image block with empty value need to be empty(without any image, and be able for the user to upload image).
**Thank you for the attention. Please help if you can :)
P.S. If you have any ideas of making that code better, write it too. Thank you.**
