This error message usually occurs when you are trying to access a variable or property that has not been defined or initialized. In this case, it seems that the variable "id" is not defined in the context where the v-on handler is being used.
To fix this error, you need to make sure that the "id" variable is declared and initialized before it is used in the v-on handler. You can do this by defining the "id" variable in the component's data object or by passing it as a prop from a parent component.
For example, if you are using the v-on directive to handle a click event on a button and you want to pass the "id" of the clicked button to a method, you can define the "id" variable in the component's data object like this:
```
<template>
<button v-for="item in items" v-bind:key="item.id" v-on:click="handleClick(item.id)">
{{ item.name }}
</button>
</template>
<script>
export default {
data() {
return {
items: [
{ id: 1, name: 'Item 1' },
{ id: 2, name: 'Item 2' },
{ id: 3, name: 'Item 3' }
]
}
},
methods: {
handleClick(id) {
console.log('Clicked item with id:', id)
}
}
}
</script>
```
In this example, the "id" variable is passed as an argument to the "handleClick" method when the button is clicked. The "handleClick" method then logs the "id" to the console.
