Background

The B-side system has many forms, and the form may contain many fields
The form with many fields brings a large amount of HTML code
In a large piece of HTML, there are mixed parameter binding, event processing and other logic, which is not conducive to the maintenance of
technology stack Vue, Element (default form layout) is suitable for the middle and backend Rapid project development

Goal

Vue plugin that quickly generates forms through json configuration.

Design goal

1. Reduce html repeated fragments

2. The form field component is extensible

3. Events and linkages are decoupled through eventbus

4. Verification can be extended

5. Form layout can be customized

6. Visual configuration

##Use

Installation

npm install charlie-autoform charlie-autoform_component_lib

Source code:

https://charlielau.github.io/autoform/#/component/autoform

Introducing the plug-in

import AutoForm from 'charlie-autoform';
import AutoForm_component_lib from 'charlie-autoform_component_lib';
Vue.use(AutoForm);
Vue.use(AutoForm_component_lib);

Basic use

demo.vue

<template>
 <p>
  <auto-form ref="tagForm1" :model="model1" :fields="fields1" :layout="layout">
   <el-form-item class="clearfix">
   <el-button type="primary">立即创建</el-button>
   <el-button>取消</el-button>
   </el-form-item>
  </auto-form>
 </p>
</template>
<script>
 export default {
 data() {
  return {
  model2: {
   name: '',
   type: []
  },
  layout2: {
   align: 'left',
   labelWidth: '100px',
   custom: false, //是否自定义布局
   inline: true //是否内联
  },
  fields2: [
   {
   key: 'name',
   type: 'input',
   templateOptions: {
    label: '审批人'
   }
   },
   {
   key: 'region',
   type: 'select',
   templateOptions: {
    label: '活动区域',
    placeholder: '请选择活动区域',
    options: [
    {
     label: '区域一',
     value: 'shanghai'
    },
    {
     label: '区域二',
     value: 'beijing'
    }
    ],
    validators:[ //校验
    // {required:true,message:'必填'}
    // ""
    ]
   }
   }
  ]
  };
 }
 };
</script>

Final effect

Add self-

Definition componentor Component directory

Vue.$autoform.RegisterDir(()=>require.context('./components/autoform', 'c'));//目录
Vue.$autoform.Register(Vue,[Components...],{prefix: "c"}) //组件对象

cHello.vue

// PATH:/components/autoform/cHello.vue
<template>
 <p>
  <p>
   <p>基本的变量可以通过"mixins"获取，这里有开发组件需要的一些变量</p>
   <p>自定义子组件：Hello</p>
   <p>当前field: {{field}}</p>
   <p>整个model: {{model}}</p>
   <p>当前model: {{model[field.name]}}</p>
   <p>layout: {{layout}}</p>
   <p>字段相关配置to: {{to}}</p>
  </p>
 </p>
</template>
<script>
 import {baseField} from "charlie-autoform";
 export default {
  mixins: [baseField],
  name: 'cHello',
  data () {
   return {};
  },
  methods: {},
  mounted(){
   //this.eventBus 事件总线
  }
 };
</script>
