I'm using vue-3
I am not familiar with vuejs and I am a newbie developer.
Situation
To add translations in batch on salesforce I wanted to code a tool. I coded a webservice in rust which gets a json and turns it into a zip for salesforce.
The client provides me with data from a spreadsheet, and I have to format it in json to send it to my webervice. I wanted to allow a copy / paste in a cell then split each line with "\ n" that I link to an input in order to edit the entry if necessary.
Problem
The input fill well with splited values, but if I change the input, the value in "computed" does not update. see image here
Questions
How can I update my value in my computed array with splited values ? V-model update my input from the computed but not the reverse. what is the best function to do this? I saw that there is reactive but I do not know if this is the right solution.
Here my code
<template>
<div>
<label for="fr">fr</label>
<input type="checkbox" value="fr" id="fr" v-model="fr.state" />
<label for="en">en</label>
<input type="checkbox" value="en" id="en" v-model="en.state" />
<label for="it">it</label>
<input type="checkbox" value="it" id="it" v-model="it.state" />
<label for="es">es</label>
<input type="checkbox" value="es" id="es" v-model="es.state" />
<label for="german">german</label>
<input type="checkbox" value="german" id="german" v-model="german.state" />
</div>
{{ formated.fr }}
<div class="Array">

Thank you for your time and help
v-model works both ways, so it needs to get something and to set something. You have only defined a get computed property but not a set. You use formated like it is a data property.
So split the computed property in a get() and a set() method make this work.
See the documentation on how this works.
