背景：

在前端系统开发中，系统页面涉及到的表单组件比较多，所以进行了简单的封装。封装的包括一些Form表单组件，如下：input输入框、select下拉框、等

实现效果：

封装组件：

封装组件的思路：

 不封装element组件，每一个input组件绑定一个form对象，例如官网。

简单封装element组件，利用for循环生成form表单的每一项el-form-item。

进一步封装，利用判断表单组件的类型，是input、select或者其它表单组件。

终极封装，把el-form表单封装成一个独立的表单，自定义命名为AreaFormItem.vue；然后单页面vue调用AreaFormItem.vue传参以及表单数据回显等操作。

封装组件的过程： 

1.不封装表单组件，代码如下： 

实现代码：【表单组件未封装】

<el-form ref="ruleForm" :model="state.form" label-width="auto" :rules="rules" class="form-box"><el-row class="form-row"><el-col :span="5" :gutter="20" style="padding-left: 0px"><el-form-item label="航次" prop="voyageNo"><el-input v-model="state.form.voyageNo" placeholder="请输入航次" /></el-form-item></el-col><el-col :span="4" :gutter="20" style="padding-left: 10px"><el-form-item label="船名" prop="name"><el-input v-model="state.form.name" placeholder="请输入船名" /></el-form-item></el-col><el-col :span="4" :gutter="20" style="padding-left: 10px"><el-form-item label="装港" prop="loadName"><el-input v-model="state.form.loadName" placeholder="请输入装港" /></el-form-item></el-col><el-col :span="5" :gutter="20" style="padding-left: 10px"><el-form-item label="卸港" prop="dischargName"><el-input v-model="state.form.dischargName" placeholder="请输入卸港" /></el-form-item></el-col><el-col :span="5" :gutter="20" style="padding-left: 10px"><el-form-item label="卸港" prop="cargoType"><el-input v-model="state.form.cargoType" placeholder="请输入卸港" /></el-form-item></el-col></el-row></el-form>

备注：因为是横着的表单，这里加入了el-row和el-col 。

2.表单组件封装，for循环渲染表单组件input：

//html
<el-form ref="ruleForm" :model="state.form" label-width="auto" :rules="rules" class="form-box"><el-row class="form-row"><el-col :span="item.span || 5" :gutter="20" style="padding-right: 10px" v-for="(item, index) in formItems":key="index"><el-form-item :label="item.label" :prop="item.key"><el-input v-model="state.form[item.key]" :placeholder="item.placeholder || '请输入'" /></el-form-item></el-col></el-row></el-form>//涉及到的变量
const state = reactive({form: {name: '',voyageNo: '',loadName: '',dischargName: '',cargoType: ''},
})
const formItems = [{type: 'input',label: '船名',key: 'name',placeholder: '请输入或者选择船名'},{type: 'input',label: '航次',key: 'voyageNo',placeholder: '请输入或者选择航次'},{type: 'select',label: '装港',key: 'loadName',placeholder: '请输入或者选择装港'},{type: 'select',label: '卸港',key: 'dischargName',placeholder: '请输入或者选择始港'},{type: 'input',label: '货种',span : 4,key: 'cargoType',placeholder: '请输入或者选择货种',}
]

3.封装一个input或者select下拉列表，封装如下：

<el-form ref="ruleForm" :model="state.form" label-width="auto" :rules="rules" class="form-box"><el-row class="form-row"><el-col :span="item.span || 5" :gutter="20" style="padding-right: 10px"v-for="(item, index) in formItems" :key="index"><el-form-item :label="item.label" :prop="item.key"><el-input v-model="state.form[item.key]" :placeholder="item.placeholder || '请输入'"v-if="item.type === 'input'" /><template v-else-if="item.type === 'select'"><el-select v-model="state.form[item.key]" :clearable="true":loading="routeState.loading_startPoint" :multiple="false":remote-method="(query) => remoteMethod_Point(query, 'cargoType')"filterable placeholder="请输入或者选择货种" remote reserve-keyword@change="(value) => blur_Point(value, 'cargoType', '')"@clear="clear_select('cargoType')"><el-option v-for="item in routeState.options_startPoint" :key="item.value":label="item.label" :value="item.label" /></el-select></template></el-form-item></el-col></el-row></el-form>
//涉及到的数据
const routeState = reactive({loading_startPoint:false,options_startPoint:[]
})

4.终极封装，把上面的form表单封装成一个vue组件，自定义命名为 AreaFormItem.vue，

AreaFormItem.vue组件，封装如下：

<template><el-form :model="data.formInline" class="area-from" :inline="true" :label-position="'left'" ref="ruleAreaFormRef":rules="data.rules"><template v-for="(item, index) in props.formItems"

调用组件AreaFormItem.vue的方式：

//调用组件
<template><AreaFormItemref="areaForm":formItems="formItems":formItemsVal="state.formItemsVal"/>
</template><script setup>
import { nextTick, onMounted, reactive, ref, watch } from "vue";
import AreaFormItem from "@/components/Form/AreaFormItem.vue";
const state = reactive({formItemsVal: {},
});
//备注：state.formItemsVal用于表单回显
const formItems = [{type: "datePicker",label: "签发日期",key: "dateOfIssue",rule: [{required: true,message: "签发日期不能为空!",trigger: "blur",},],},{type: "datePicker",label: "截止日期",key: "deadline",rule: [{required: true,message: "截止日期不能为空!",trigger: "blur",},],},{type: "select",label: "文件类型",key: "type",optionsData: [{label: "船舶经营许可证",value: 0,},{label: "船舶管理人许可证",value: 7,},],defaultVal: 0,rule: [{required: true,message: "文件类型不能为空!",trigger: "blur",},],},{type: "uploadSingleImg",label: "渡船证书",key: "file",option: {uploadParames: {fileType: 0, //渡船相关证书},img_bg: "table/upload.png",info: "upload",text: "上传",importUrl: BASEUrl + "/data/file/upload",},width: "100%",getRowInfo: (data) => {console.log("上传图片的结果", data);state.formItemsVal.file = data;},removeImg: (data) => {api.fileApi.deleteFile({ fileName: data.fileName, fileType: data.fileType }).then((res) => {if (res.status === 200 && res.data.code === 200) {ElMessage({type: "success",message: "删除成功",});}}).catch((err) => {console.log(err);});},rule: [{required: true,message: `${state.pageTheme}不能为空!`,trigger: "blur",},],},
];
<script>

 写到这儿就实现了表单组件的封装，根据调用组件传参的formItems变量的type类型渲染不同的表单组件例如：input、select等组件。。。最终随着项目的进行，表单组件的其他类型：

'location', 'medium','password', 'sexRadio', 'coordinate','radio','textarea','multipleSelect', 'uploadFile','uploadSingleImg',也会封装。
