Implementing 'Select All' and 'Unselect All' Logic

To achieve the 'Select All' functionality, the code utilizes a computed property named checkAll. This property is smartly designed to determine whether all checkboxes are checked or not. If all checkboxes are selected, the 'Select All' checkbox is automatically checked. Conversely, if any checkbox is unchecked, the 'Select All' checkbox is also unchecked.

The checkAll property is computed based on the checked array's length, which stores the selected country names. When the 'Select All' checkbox is toggled, the set method within the computed property handles the logic. If the 'Select All' checkbox is checked, it populates the checked array with all country names; if unchecked, it clears the checked array.

<v-container>
    <h3>Vuetify Checkbox Select All | Unselect All</h3>
    <v-row>
        <v-col class="form-check">
            <v-checkbox v-model="checkAll" label="Select all" id="selectAll"></v-checkbox>
        </v-col>
    </v-row>

    <v-row>
        <v-col v-for="c in country" :key="c.id">
            <v-checkbox v-model="checked" :value="c.countryName" :label="c.countryName" :id="c.id"></v-checkbox>
        </v-col>
    </v-row>

    <v-row>
        <p>Checked Value: {{ checked }}</p>
    </v-row>
</v-container>

Run

Now, let's break down the JavaScript part of the code:

<script>
    new Vue({
        el: '#app',
        vuetify: new Vuetify(),
        data() {
            return {
                country: [
                    { id: '5', countryName: 'CANADA' },
                    { id: '6', countryName: 'GERMANY' },
                    { id: '7', countryName: 'FRANCE' },
                    { id: '8', countryName: 'BRAZIL' },
                    { id: '9', countryName: 'JAPAN' },
                    { id: '10', countryName: 'CHINA' },
                ],
                checked: []
            };
        },
        computed: {
            checkAll: {
                get() {
                    return this.country ? this.checked.length === this.country.length : false;
                },
                set(value) {
                    if (value) {
                        this.checked = this.country.map((c) => c.countryName);
                    } else {
                        this.checked = [];
                    }
                }
            }
        }

    })
</script>

In the JavaScript part, we define a Vue instance. We have a data property that holds an array of countries and an empty array called checked to keep track of the selected checkboxes.

The checkAll property is a computed property that calculates whether the "Select All" checkbox should be checked. It returns true if all checkboxes are selected and false otherwise. When the "Select All" checkbox is changed, the setter is triggered, and it either selects or deselects all the checkboxes based on its value.
