Question

Filter a Vue list based on a checkbox that can be either checked or unchecked

I am currently working on my Vue app and aiming to filter a list to display only entries that have been moderated.

However, I am encountering an issue where when the checkbox is checked, I receive all the results that are true, and when the checkbox is unchecked, I get all the results that are false. What I actually want is for no filtering to occur when the checkbox is empty, and to only show results that have been moderated when the checkbox is checked.

Below is what I have tried:

<input type="checkbox" v-model="showUnModerated" /> Show only unmoderated listings</label>

Here is my filtering code:

return this.listing.listings.filter(listing => (this.showUnModerated ? 1 : 0) === listing.moderated);

By incorporating an array of modified lists and utilizing the v-model with checkboxes, you can easily access the modified list.

new Vue({
  el: '#app',
  data: {
    showChecked: []
  }
})

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>

<div id='app'>
  <input type="checkbox" value='1' v-model="showChecked" /> element 1</label> <br>
  <input type="checkbox" value='2' v-model="showChecked" /> element 2</label>
  <br> {{showChecked}}
</div>
