*SOLVED* Component with multiple checkboxes and ONE v-model

Asked By: Anonymous

I’m building “base” components for my application, mostly for form management. So far I’ve made a custom input, textarea, select, and radio. However, all those components only have “one” value at a time.

For radios and checkboxes, my component builds multiple radios/checkboxes at once, all attached to the same v-model. Howevever, my checkbox component is not working as intended. Instead of storing “all the checked checkboxes” in an array in the v-model, it only registers the last one clicked 🙁.

How can I override the “change” event so that it updates the attached model accordingly, by adding/removing the element from the array?

Here’s my code for the checkbox component:

/**
 * @description Component used to display a group of checkboxes
 * @author Jordan Kowal
 * @date 2019-11-30
 * @param name String, name attribute
 * @param alignment String, defines item alignment and should be "centered", "left", or "right"
 * @param block Boolean, whether items are displayed as "block" or "inline-block"
 * @param entries Array, list of objects with the following keys: label, value, active
 * @param errors Array, list of error messages
*/
Vue.component("checkbox-group", {
    props: {
        name: String,
        alignment: String,
        block: Boolean,
        entries: Array,
        errors: Array,
    },
    template:
        "<div class='field'>
            <p class='help is-danger' v-for='message in errors'>
                @{message}
            </p>
            <div class='control' :class='"has-text-" + alignment'>
                <template v-for='entry in entries'>
                    <label class='checkbox'>
                        <input
                            type='checkbox'
                            :name='name'
                            :checked='entry.active'
                            :value='entry.value'
                            @change='$emit("input", $event.target.value)'
                        />
                        @{entry.label}
                    </label>
                    <br v-if='block'>
                </template>
            </div>
        </div>",
});

Exemple of use:

<checkbox-group
    name="id"
    alignment="centered"
    :block="true"
    v-model="languageForm.fields.languages"
    :entries="languageForm.entries.languages"
    :errors="languageForm.errors.languages"
></checkbox-group>

Take a look what v-model on custom components does

<mycomponent v-model="data" />

is same as

<mycomponent 
  v-bind:value="data"
  v-on:input="data= $event" />

So if you do $emit("input", $event.target.value) inside of your component, whatever $event.target.value is, it replaces your model. But you need an “input” event so the v-model on your component works. value emitted just has to be in the same format as a model you are receiving.

On top of that whats the point of having a model and at the same time support entries.active ? It’s clear duplicity. Passed model should be only thing that decides whether checkbox is checked or not….

Do it like this:

Vue.component("checkbox-group", {
  props: {
    name: String,
    alignment: String,
    block: Boolean,
    entries: Array,
    errors: Array,
    value: Array
  },
  data() {
    return {
      model: this.value
    }
  },
  watch: {
    model: function(val) {
      this.$emit("input", val)
    }
  },
  template:
    "<div class='field'>
            <p class='help is-danger' v-for='message in errors'>
                @{message}
            </p>
            <div class='control' :class='"has-text-" + alignment'>
                <template v-for='entry in entries'>
                    <label class='checkbox'>
                        <input
                            type='checkbox'
                            :name='name'
                            :value='entry.value'
                            v-model='model'
                        />
                        {{entry.label}}
                    </label>
                    <br v-if='block'>
                </template>
            </div>
        </div>"
});

Changes:

  1. added value prop – its set by Vue to a value inside v-model attribute of your component
  2. introduce model in data – variable holds current state of your checkboxes. At the begging it’s initialized from v-model
  3. removed :checked=... because its a duplicity. Checked state of checkboxes is driven by model
  4. added watcher – every time model inside your component is changed (by v-model on checkboxes), emit an event so the parent’s model is updated
