The presence of Vue refs is evident, though accessing refs[key] results in an

I am facing an issue with dynamically rendered checkboxes through a v-for loop. I have set the reference equal to a checkbox-specific id, but when I try to access this reference[id] in mounted(), it returns undefined.

Here is the code snippet:

let id = this.$route.query[key];
console.log(id);
console.log(this.$refs);
console.log(this.$refs[id]);

Resulting Output:

Can anyone shed some light on what might be causing this issue? The references are being printed and should exist since it's in the mounted() lifecycle hook. Changing the reference does not seem to solve the problem. Thank you for any help.

Answer №1

When you utilize refs in conjunction with v-for, the component / DOM nodes will be stored directly as an array under the specified variable name

For instance

<list-item
v-for="item in items" 
:key="item.id"
:value="item.value"
ref="items"
/>

To access these refs in your component, use this syntax:

this.$refs.items[index]
