如何在 object 的特定数组中插入一个值

Question

I am using Vue ( vuetify ) v-data.table to show some data, Its working fine, in the same time I am trying to show some data from another api, So I need to know how to push a items inside of a array of object.

axiosThis.tableDataFinal[i].push(axiosThis.printsumget[i])

I am getting an error .push is not a function

As per your code, Looks like you are trying to perform a push operation on an object instead of an array . That's the reason it is giving you that error.

Also, As per my understanding. Your API response will give you an array of objects. So instead of using .push , You can use Destructuring assignment

Live Demo :

 new Vue({ el: '#app', vuetify: new Vuetify(), data () { return { headers: [ { text: 'Dessert (100g serving)', align: 'start', sortable: false, value: 'name', }, { text: 'Calories', value: 'calories' } ], desserts: [ { name: 'Frozen Yogurt', calories: 159 }, { name: 'Ice cream sandwich', calories: 237 } ] } }, mounted() { // Another axios api call. Just for a demo purpose I am using mock array here. You can replace it with an actual API response. const res = [{ name: 'Burger', calories: 200 }, { name: 'Chocolate Cake', calories: 250 }]; this.desserts = [...this.desserts, ...res]; } })
