Vue 中 的 mixin 混入(合)
1:说明
/* ## mixin(混入) 1. 功能:可以把多个组件共用的配置提取成一个混入对象 2. 使用方式: 第一步定义混合: ``` { data(){....}, methods:{....} .... } ``` 第二步使用混入: 全局混入:```Vue.mixin(xxx)``` 局部混入:```mixins:['xxx'] ``` */

3:代码内容
vue.config.js
const { defineConfig } = require('@vue/cli-service') module.exports = defineConfig({ transpileDependencies: true, lintOnSave:false /*关闭语法检查*/ })
main.js
//引入Vue import Vue from 'vue' //引入App import App from './App.vue' //关闭Vue生产提示 Vue.config.productionTip=false; //全局引用 minix import { mixinGlobalData ,mininGlobalData2} from "@/mixin"; Vue.mixin(mixinGlobalData); Vue.mixin(mininGlobalData2); // 创建Vm const vm = new Vue( { el:'#app', render: (h) => h(App) });
