1.全局注册方法

import store from '@/store'
app.config.globalProperties.$store = store();

2.pinia的使用

注意：pinia不要使用全局注册方法，会导致在当前页面修改数据失败 ①首先在main.ts中注册

import { createPinia } from "pinia";
app.use(createPinia())

②store/index.ts中

import { defineStore } from 'pinia'

export const exportStore = defineStore({
  id: 'shi',
  state: () => {
    return {
      homeAnchor: 9999,
      solutionAnchor: 9999,
      successCaseAnchor: 9999,
      aboutUsAnchor: 9999,
    }
  },
  getters: {},
  actions: {}
})

③其他组件就可以使用了

import { exportStore } from "@/store";
const pinia = exportStore()

然后通过pinia.solutionAnchor就可以取到值了
