vue 封装自定义组件

• 建立组件.vue，其中props是该组件的属性配置项，data能够根据ref获得

<template id="sjld">
	<el-form :model="formData" ref="reference" :rules="validatoRule" label-width="120px" :inline="true" >

<script>
    export default {

            reference: Object,
            validatoRule: Object,
            tableColumnType: Array,

            tablePcStyle: Array,
            tableMobileStyle: Array,
            addColumn: Function,
            deleteColumn: Function

        },
        methods: {
        	selsChange: function (sels){
        		this.sels = sels;
        	}
        },
        mounted(){
           
        },
        computed: {
        }
    }
</script>
<style >
.el-row {
	line-height: 30px;
    margin-bottom: 10px;
}
.el-table-column {
	margin: 0px;
}
</style>

• 使用自定义组件，ref配置组件，就可使用this.$refs.editForm获得该组件，就能够访问该组件暴露的data和method

import sysTableDetail from '../../components/sysTableDetail.vue'

components: {
            'sysTableDetail': sysTableDetail
        },

<sysTableDetail :formData="editForm" ref="editForm" :validatoRule="editFormRules" :tableColumnType="tableColumnType" :tableTypeOptions="tableTypeOptions" :tablePcStyle="tablePcStyle" :tableMobileStyle="tableMobileStyle" :addColumn="addColumn" :deleteColumn="deleteColumn">
			</sysTableDetail>

ok，能够了，固然组件也能够注册在main.js，成为全局组件
