Vue 3: How Do I Exclude Specific Items from a q-select Using a Computed Property?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

Good morning,
I have a q-select component that displays a list of employers from an array with identifiers and labels. I want to exclude specific items from this list (specifically the ones corresponding to lines 6 and 7).

Here is my q-select component code:

HTML
<q-select
            dense
            v-model="DataOrganisation.id_ref_employeur"
            :options="filtrageListeEmployeurs"
            :disable="DisableEmployeur"
            :rules="[val => !!val || 'L'employeur est obligatoire']"
            options-dense
            option-value="id"
            option-label="nom"
            emit-value
            map-options
            class="custom-q-select"
          />

My data is structured as follows:

JAVASCRIPT
const OptionsListeEmployeurs = JSON.parse(localStorage.getItem('Liste_Employeurs'))

[{id: 10, nom: "AIRPL"}, 
{id: 9, nom: "Autres"}, 
{id: 2, nom: "CNRS"}, 
{id: 12, nom: "CTS"}, ...
0: {id: 10, nom: "AIRPL"}
1: {id: 9, nom: "Autres"}
2: {id: 2, nom: "CNRS"}
3: {id: 12, nom: "CTS"}
4: {id: 11, nom: "ESB"}
5: {id: 7, nom: "ICAM"}
6: {id: 1, nom: "IMT Atlantique"}
7: {id: 5, nom: "IMT (autre)"}
8: {id: 14, nom: "IMT Transfert"}
9: {id: 3, nom: "INRIA"}
10:{id: 13, nom: "UBO"}
11:{id: 4, nom: "Univ Nantes"}

This is my filtering function in a computed property:

JAVASCRIPT
const filtrageListeEmployeurs = computed(() => {
  return OptionsListeEmployeurs.filter(item => ![1, 5].includes(item.id))
})

How can I exclude the items from lines 6 and 7 in my list?

Thank you.

Below is one way to do that using the filter method on your OptionsListeEmployeurs array. Since line 6 and line 7 in your data have id values 1 and 5 respectively, your computed property can filter them out like this:

JAVASCRIPT
const filtrageListeEmployeurs = computed(() => {
  return OptionsListeEmployeurs.filter(item => ![1, 5].includes(item.id))
})

In this code, the filter method iterates over each item in OptionsListeEmployeurs and removes those whose id is either 1 or 5. This way, the q-select will only display the remaining items.

Make sure that the id values you want to exclude (1 and 5) correctly correspond to the lines you wish to remove.
