mixin

mixin文件里的index.js导出

export default{
    mounted() {
           
    },
    methods: {
        getdata(){
            this.name
        }
    },
    data() {
        return {
            name:'jack'
        }
    },
}

组件接收

先引入文件夹 然后有一个方法 mixins:[mixin],

<script>
import mixin from '../mixin'
 export default {
  mixins:[mixin],
   name: '',
//接收父组件传递过来的参数
   props: {
   },
   components: {

   },
    data() {
        return {
            msg:'jack'
        }
    },
    mounted() {
     this.getdata(
       this.mag= this.name
     )
   },
