（十二）store 之间互相访问

一、store 之间互相访问

• note.js

import { ref } from 'vue'
import { defineStore } from 'pinia'

export const useNoteStore = defineStore('note', () => {
    cosnt noteList = ref([
        {
            title: '标题',
            desc: '详情内容'
        }
    ]),

    return {
        noteList
    }
})

• user.js

import { ref } from 'vue'
import { defineStore } from 'pinia'

export const useuserStore = defineStore('user', () => {
    cosnt user = ref(
        {
            name: 'bob',
            phone: 15729837802,
            emial: '2966211270@qq.com'
        }
    ),

    return {
        user
    }
})

二、只有当用户登录了才能进行添加

import { ref } from 'vue'
import { defineStore } from 'pinia'

export const useuserStore = defineStore('user', () => {
    cosnt user = ref(
        {
            name: 'bob',
            phone: 15729837802,
            emial: '2966211270@qq.com'
        }
    ),

    function isLoggedIn() {
        return user.value != null
    }

    return {
        user,
        isLoggedIn
    }
})

三、在 note.js 中访问其他 store

• 获取方法和在组件当中获取是一样的

import { ref } from 'vue'
import { defineStore } from 'pinia'
import { useUserStore } from './user.js'

export const useNoteStore = defineStore('note', () => {
    cosnt noteList = ref([
        {
            title: '标题',
            desc: '详情内容'
        }
    ]),


    const userStore = useUserStore()
    function addNote() {
        if(userStore.isLoggedIn) {
            setTimeout(() => {
                noteList.push({
                    title: '标题x'
                    desc: '详情内容x'
                })
            }, 2000)
        }
    }

    return {
        noteList
    }
})
