Error in v-on handler: "ReferenceError: id is not defined"

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.

Error in v-on handler: "ReferenceError: isCollect is not defined"

根据引用[1]中的解释，问题出现在v-on命令中的isCollect变量没有定义。你在代码中已经在data中定义了isCollect变量，但是在方法中使用实例上的变量时，必须使用this来指向这个变量。所以，你需要在v-on命令中使用this.isCollect来引用isCollect变量，这样问题就可以解决了。
