Using the v-for variable from a slot in the parent component: A step-by-step guide

Can you help me troubleshoot this error I'm encountering while trying to utilize a variable in the slot from v-for in Vue.js?

The issue of "Property or method "slide" is not defined on the instance but referenced during render. Make sure that this property is reactive, either in the data option, or for class-based components, by initializing the property."

This is how I am implementing the component:

<Slides v-model="slides">
  <AnotherComponent v-model="slide.someproperty" />

Within the Slides component, there is a v-for loop:

<div v-for="(slide, index) in value" :key="slide.id">
        <comp1 v-model="slide.prop1"></dropper>
        <slot></slot>
</div>

Answer №1

Scoped slots provide a solution for this specific scenario.

For instance, within your Slides template:

<slot :slide="slide"></slot>

Then in the parent component...

<Slides v-model="slides">
  <AnotherComponent slot-scope="{ slide }" v-model="slide.someproperty"/>

Please note that if you're using Vue version less than 2.5, remember that the slot-scope can only be used on a <template> element.
