我有两个组件rad-list和rad-card,我在rad-list中放置了一个插槽元素,我将在其中放置rad-card,现在rad-card需要访问父rad-list组件中的computeResults数据我可以使用Vue插槽访问它吗?

RAD列表

<template>
<div class="RADlist_maincontainer">
    <layout-pagination-1 v-show="pagination.last_page > 1" :pagination="pagination" @paginate="paginate({ page:pagination.current_page, paginate:paginate })"></layout-pagination-1>
    <div class="RADlist_wrapper">
        <!--rad-card, or any other component which will use computedResults GOES HERE-->
        <slot></slot>
    </div>
    <layout-pagination-1 v-show="pagination.last_page > 1" :pagination="pagination" @paginate="paginate({ page:pagination.current_page, paginate:paginate })"></layout-pagination-1>
</div>
</template>

这是我的模板中的样子:

<rad-list model="Discount" module="Discount" results="discounts">
        <rad-card :item="result" v-for="result in computedResults" :key="result.id" :model="module"></rad-card>
    </rad-list>

我的完整RADlist组件Justi,以备不时之需:

<template>
<div class="RADlist_maincontainer">
    <layout-pagination-1 v-show="pagination.last_page > 1" :pagination="pagination" @paginate="paginate({ page:pagination.current_page, paginate:paginate })"></layout-pagination-1>
    <div class="RADlist_wrapper">
        <!--rad-card, or any other component which will use computedResults GOES HERE-->
        <slot></slot>
    </div>
    <layout-pagination-1 v-show="pagination.last_page > 1" :pagination="pagination" @paginate="paginate({ page:pagination.current_page, paginate:paginate })"></layout-pagination-1>
</div>
</template>
<!--SCRIPTS-->
<script>
import { mapState } from 'vuex';
export default{
name: 'RADlist',


computed:
{
    computedResults: function()
    { 
        return this.$store.state[this.module][this.results];
    },
    pagination: function()
    { 
        return this.$store.state[this.module].pagination;
    },
    ...mapState('Loader', ['loader'])
},


props:
{
    component: { default:'rad-card', type:String },
    module: { default:'Post', type:String },
    action: { default:'list', type:String },
    results: { default:'posts', type:String },
    page: { default:1, type:Number },
    paginate: { default:6, type:Number },

},


mounted()
{
    console.log(this.$options.name+' component successfully mounted');
    this.$store.dispatch(this.module+'/'+this.action, { page: this.page, paginate: this.paginate, loaderId:2473});
},


}
