Utilize Vue.js functions within data through the Vue.js context

I'm trying to incorporate a function as a data property. While it works for the 'works' data property, I need access to the this context within the function in order to calculate values from the shoppingCart property. Is there a way to achieve this? If so, how can I correct my approach?

 new Vue({
    el: '#vueApp',

    data: {

        shoppingCart: [],      

        works : function () {
            return "testfunc";
        },
        totalPriceCalcProperty : function () {

            this.totalPrice = this.shoppingCart.reduce(function(total, cartItem){

                console.log(total, cartItem);
                return total + parseFloat(cartItem.price);

            }, 0);
        }
    },

    methods: {

       totalPriceCalc: function () {

            this.totalPrice = this.shoppingCart.reduce(function(total, cartItem){

                console.log(total, cartItem);
                return total + parseFloat(cartItem.price);

            }, 0);
        },
    }

Answer №1

It is best practice to utilize methods instead of relying on data.
Using data primarily for storage purposes can lead to a more organized code structure.

With methods, you have the flexibility to access properties from data or property by simply calling this.xxx.
