Vue3中经验总结

在setup中获取全局this下属性

// 通过在main.js中将值绑定在vue全局上
import { createApp } from 'vue';
import App from './App.vue';
const app = createApp(App);
app.config.globalProperties.baseurl = "http://xxx.com/";

// 页面组件
<script lang="ts" setup>
import { getCurrentInstance } from "@vue/runtime-core";
// 通过getCurrentInstance获取vue实例
const vm = getCurrentInstance().proxy;
console.log(vm.baseurl);
</script>
