How to get this from a higher context level?

Question

JavaScript

Perhaps the description is a little wrong, but I do not know how to describe it more accurately.
I use Vue, the component has data:

data: function () {
            return{
                suggestionOptions: {
                    onSelect (suggestion) {
                        document.querySelector('#index').value = suggestion.data.postal_code;
                    },
                },
            }
        },

I connected the plugin and in the options one of the options is a function.
She has her this. I need to assign a value from data or from store to what it gives out. It gives out what after is equal to now, with a certain plug-in action. I can’t understand how I can get in it not ITS this, but the one that is “above”, this Vue component. I hope I explained clearly.

Answer 1

onSelect: () => {}
