问题相关代码，请勿粘贴截图

Home.vue

<template>
    <el-button @click="filterFromHome()">filterFromHome</el-button>
    <Test></Test>
</template>

<script>
    import Test from "./Test.vue"
    import useTest from "@/hooks/useTest"
    import {toRefs} from "vue"

    export default {
        name: 'Home',
        components: {Test},

        setup() {

            const {filterFromHome} = useTest()

            return {
                filterFromHome
            }
        }
    }
</script>

<style scoped>

</style>

useTest.js

/**

import {reactive, watch} from "vue"

export default function () {

    let arr = _.map(new Array(100), (item, index) => {
        return {
            id: index + 1,
            name: `test${index + 1}`,
        }
    })
    const info = reactive({
        list: arr,
        sourceList: arr
    })

    watch(info, (val, oldVal) => {
        info.list = val.list
        console.log("useTest.js", val);
    })

    const filterFromHome = () => {
        info.list = _.filter(info.sourceList, item => item.id <= 50)
        console.log("Home.vue", info);
    }

    const filterInfoList = (row) => {
        info.list = _.filter(info.sourceList, item => item.id <= row.id)
    }

    return {
        info,
        filterInfoList,
        filterFromHome
    }
}

Test.vue

<template>
    <div class="test">
        <p v-for="item in info.list" :key="item.id" @click="filterInfoList(item)">
            name:{{item.name}}
        </p>
    </div>
</template>

<script>
    import useTest from "@/hooks/useTest"
    import {watch, toRefs} from "vue"

    export default {
        name: "Test",
        setup() {
            const {info, filterInfoList} = useTest()

            watch(info, (val) => {
                console.log("Test.vue", val);
            })

            return {
                info,
                filterInfoList,
            }
        }
    }
</script>

<style scoped>
    .test {
        border: 1px solid #333;
    }
    .test p {
        cursor: pointer;
    }
</style>

运行结果及报错内容

点击按钮 filterFromHome 后，子组件模板未更新？？

你的usetest是一个函数，在home和test中分别调用，生成的是两个实例，是没有关联的
