script中使用ts的写法，以及store和router在.vue页面的使用方法，需要从vue-routerhe 和vuex中导出useStore和useRoute(userouter)

通过getCurrentInstance（）方法可以获得组件实例

<script lang="ts">
import { defineComponent, computed, onMounted, watch,ref,getCurrentInstance,reactive,nextTick ,toRefs} from 'vue'
import {
  useStore,
  mapState,
  // mapMutations,
  // mapActions,
  // mapGetters
} from 'vuex'
import {useRoute,useRouter,useLink,UseLinkOptions} from "vue-router"
import { useI18n } from "vue-i18n";
import {data} from "@/utils/TypeState"
import HelloWorld from '@/components/HelloWorld.vue'
export default defineComponent({
  components:{
    HelloWorld
  },
  setup(props, context){
    console.log('context',context);
    const age=ref<Number>(10)
    const count=ref(50)
    const name=ref<any>(0)
    const store=useStore()
    const {proxy}:any=getCurrentInstance()
    const number=ref<string|Number>(store.state.app.age)
    const Route=useRoute()
    const RouteLink=useLink
    const data = reactive<data>({
      tableData: [
        {
          time: '姓名1'
        }
      ],
      language:[{
        name:'中文',
        value:'zh'
      },
      {
        name:'英文',
        value:'en'
      }],
      seleLanguage:'zh'
    })
    const { t } = useI18n();
    const languageD=()=>{
      proxy.$i18n.locale=data.seleLanguage
    }
    console.log(store.state.app.allMenuList instanceof  Array);
    console.log(proxy);
  // 监听指定基础类型数据
    const addNum=()=>{
      //  name.value=Number(name.value) +1
      name.value++
    }
    watch(name, (now, prev) => {
          console.log(now, prev, 'count')
    })
    // 监听reactive创建的响应式变量,可以直接监听对象，必须使用内联函数
    watch(() => data.tableData, (now, prev) => {

    })

    }
    const toDelit=():void=>{

    }
    return {
