I've been encountering an issue with using this.$refs within my Vue component. No matter where I place it - whether in methods, lambdas, or lifecycle hooks - I consistently receive errors indicating that 'this' may be undefined. As a newcomer to Vue, I'm certain that the solution is likely simple. Can anyone provide guidance on how to resolve this?
<template>
<div ref="tabtable"></div>
</template>
<script setup lang="ts">
import { onBeforeMount, onMounted, ref } from 'vue';
import { InventoryDataService } from '@/services/InventoryDataService';
import type { IInventoryItem } from '@/assets/interfaces/iinventoryitem';
import type { IVendor } from '@/assets/interfaces/ivendor';
import { TabulatorFull as Tabulator } from 'tabulator-tables';
// TODO: Remove this!
import { TestVendor } from "@/assets/testdata/fakevendor";
let inventory = ref<IInventoryItem[]>();
let tabulator: Tabulator;
const dataService = new InventoryDataService();
const getInventory = async (vendor: IVendor): Promise<IInventoryItem[]> => {
return await dataService.getInventory(vendor)
};
// The reference to 'this' below is currently undefined
onMounted(async () => {
tabulator = new Tabulator(this.$refs.tabtable, {<...rest of my code here});
});
onBeforeMount(async () => {
inventory.value = await getInventory(TestVendor);
});
</script>
