实现表单项按配置展示

实现表单展示方式通过数据库表配置实现

1. 数据库配置表
2. 表单元素按数据库配置来确定展示形式text，时间框，文本框等

3. 配置校验，校验实现

   一、数据库配置表

   ①建表

   create table *_config
   (
   item_id bigint auto_increment comment '主键',
   form_id bigint not null comment '表单编号',
   item_type varchar(10) null comment '对象类型，1、字段物理名称、2：属性ID，3：模块标识',
   item_key varchar(30) null comment '属性id',
   item_name varchar(30) null comment '字段名称',
   item_value varchar(30) null comment '属性值',
   default_value varchar(30) null comment '默认值',
   show_type varchar(30) default 'text' not null comment '展示形式 text、date、picker、smartInput',
   is_display char null comment '是否显示，0：否、1：是',
   is_editable char null comment '是否可编辑，0：否、1：是',
   is_data_mask char null comment '是否脱敏，0：否、1：是',
   mask_type varchar(5) null comment '脱敏类型，1：名称、2：证件号码、3：地址、4：电话号码',
   check_rule varchar(50) null comment '校验规则名称',
   remark varchar(300) null comment '备注',
   seq tinyint not null comment '顺序',
   status_cd char(2) default '00' not null comment '状态 00：有效，其他：无效',
   CREATE_DATE datetime default CURRENT_TIMESTAMP null comment '创建时间'
   )
   comment '表单属性项配置';

   ②插入示例记录

   INSERT INTO *_config(item_id, form_id, item_type, item_key, item_name, item_value, default_value, show_type, is_display, is_editable, is_data_mask, mask_type, check_rule, remark, seq, status_cd, CREATE_DATE)
   VALUES (1, 2, '1', '20210810067', '支局名称', '', null, 'text', '1', '0', '0', null, null, '', 1, '00', '2022-02-28 09:57:47');
   INSERT INTO *_config(item_id, form_id, item_type, item_key, item_name, item_value, default_value, show_type, is_display, is_editable, is_data_mask, mask_type, check_rule, remark, seq, status_cd, CREATE_DATE)
   VALUES (3, 2, '1', '20210810069', '小区名称', '', null, 'smartInput', '1', '1', '0', null, '', '', 3, '00', '2022-02-28 09:58:05');
   INSERT INTO *_config(item_id, form_id, item_type, item_key, item_name, item_value, default_value, show_type, is_display, is_editable, is_data_mask, mask_type, check_rule, remark, seq, status_cd, CREATE_DATE)
   VALUES (6, 2, '1', '20210810072', '合约到期时间', '', null, 'date', '1', '1', '0', null, null, '', 6, '00', '2022-02-28 09:58:12');
   INSERT INTO *_config(item_id, form_id, item_type, item_key, item_name, item_value, default_value, show_type, is_display, is_editable, is_data_mask, mask_type, check_rule, remark, seq, status_cd, CREATE_DATE)
   VALUES (7, 2, '1', '20210810074', '现有宽带速率', '', null, 'picker', '1', '1', '0', null, null, '', 7, '00', '2022-02-28 09:58:14');

二、表单页面实现

<van-form ref="attrFrom" @submit="onSubmit">
    <div v-for="attr in attrList">
        <div v-if="attr.cfg.showType == 'text'">
          <van-field v-model="attr.value" :label="attr.attrName"
            :readonly="attr.cfg.isEditable=='0'"
            :clickable="attr.cfg.isEditable=='1'"
            label-align="right"
            label-width="8em"
            :rules="te(attr.cfg.checkRule)"
            :right-icon="attr.cfg.isEditable=='1'?'edit':''"
            @change="onSubmit"
            @click="clickField(attr.cfg)"
          >
          </van-field>
        </div>
        <div v-else-if="attr.cfg.showType == 'date'">
          <van-field v-if="attr.cfg.isEditable=='0'" v-model="attr.value" :label="attr.attrName"
            readonly
            label-align="right"
            label-width="8em"
          >
          </van-field>
          <van-field v-if="attr.cfg.isEditable=='1'" v-model="attr.value" is-link readonly
            :label="attr.attrName"
            label-align="right"
            label-width="8em"
            @click="clickField(attr.cfg)"
          >
          </van-field>
          <van-calendar 
            v-if="attr.cfg.isEditable=='1'" 
            v-model:show="attr.cfg.isShowPopup" 
            @confirm="(value) => onConfirmDate(value, attr)">
          </van-calendar>
        </div>
        <div v-else-if="attr.cfg.showType == 'picker'">
          <van-field v-if="attr.cfg.isEditable=='0'" v-model="attr.cfg.valueMap[attr.value]" :label="attr.attrName"
            readonly
            label-align="right"
            label-width="8em"
          >
          </van-field>
          <van-field v-if="attr.cfg.isEditable=='1'"
            v-model="attr.value"
            is-link
            readonly
            :label="attr.attrName"
            name="picker"
            label-align="right"
            label-width="8em"
            @click="clickField(attr.cfg)">
          </van-field>
          <van-popup round v-if="attr.cfg.isEditable=='1'" 
          v-model:show="attr.cfg.isShowPopup" 
          position="bottom">
            <van-picker
              show-toolbar
              confirm-button-text="确定"
              cancel-button-text="取消"
              :columns="values"
              value-key="attrValueName"
              :colunmsFieldNames="{text:'attrValueName'}"
              @confirm="(value) => onConfirm(value, attr)"
              @cancel="onCancel(attr.cfg)"
            />
          </van-popup>
        </div>
        <div v-else-if="attr.cfg.showType == 'smartInput'">
          <van-field v-if="attr.cfg.isEditable=='0'" v-model="attr.value" :label="attr.attrName"
            readonly
            label-align="right"
            label-width="8em"
          >
          </van-field>
          <van-field v-if="attr.cfg.isEditable=='1'"
           name="my-field" 
           :label="attr.attrName"
           label-align="right"
           label-width="8em"
           :right-icon="'edit'"
           >
            <template #input>
              <smart-input id="service" @sync="syncService" :props="attr"></smart-input>
            </template>
          </van-field>    
        </div>
    </div>
</van-form>

三、校验实现

data () {

  return {
    loadingMap: {},
    showSubmit: false,
    showPicker: {},
    attrList: [],
    attrMap: {},
    cfgMap: {},
    customFieldName: {
      text: 'attrValueName',
      values: 'valueList'
    },
    values: [],
    rules: {
      isMobile: [
        {
          pattern: /^1[0-9]{10}$/,
          message: '请输入正确手机号'
        }
      ],
      isNumber: [
        {
          pattern: /^[0-9]+(.[0-9]{1,3})?$/,
          message: '请输入正确数字'
        }
      ]
    },
    addrName: '',
    addrId: ''
  }
},
