Auto select rows in v-data-table - vuetify.js

Question

I would like to programmatically checkmark a row in a v-data-table when an external listener notifies me of a particular value.
As an example, here is a Vuetify selectable table: https://vuetifyjs.com/en/components/data-tables#selectable-rows
In the example, If I were passed the value of 'Gingerbread' after the table and its data have already been instantiated, how would I programmatically select that corresponding row?

Answer 1

You can do this by pushing your values in your model like this:
HTML:
<div id="app">
<v-app id="inspire">
<v-btn #click="select">button</v-btn>
<v-data-table
v-model="selected"
:headers="headers"
:items="desserts"
:single-select="singleSelect"
item-key="name"
show-select
class="elevation-1"
>
<template v-slot:top>
<v-switch v-model="singleSelect" label="Single select" class="pa-3"></v-switch>
</template>
</v-data-table>
</v-app>
</div>
VueJS:
new Vue({
el: '#app',
vuetify: new Vuetify(),
methods: {
select: function() {
let result = this.desserts.find((dessert) => {
return dessert.name == 'Gingerbread'
})
this.selected.push(result)
}
},
data () {
return {
singleSelect: false,
selected: [],
headers: [
{ text: 'Dessert (100g serving)', value: 'name' },
{ text: 'Calories', value: 'calories' },
],
desserts: [
{ name: 'Gingerbread', calories: 356 },
{ name: 'Jelly bean', calories: 375 }
],
}
},
})

The v-data-table component has a property called filteredItems which you can use to add items to the selected array
<v-data-table v-model="selected":items="itemsArray" ref="table"></v-data-table>
function selectAll() {
this.$refs.table.filteredItems.map(item => {
if(...some condition...) {
this.selected.push(item)
}
})
}
