vue根据后端数据生成form表单

后端数据格式

 formData: [
        {
          label: '角色名称',
          id: 'name',	 //key值
          type: 'input', //form的属性
          placeholder: '请输入角色名称',
        },
        {
          label: '渠道',
          type: 'select',
          id: 'channel',
          placeholder: '请选择渠道',
          radio: [
            { key: 1, value: '安卓' },
            { key: 2, value: 'IOS' },
          ], // 选项
        },
        {
          label: '时间',
          type: 'datePicker',
          id: 'date',
          placeholder: '请选择时间',
        },
        {
          label: '复选框',
          type: 'checkbox',
          id: 'checkbox',
          placeholder: '请选择',
          checkbox: [
            { key: 1, value: '安卓' },
            { key: 2, value: 'IOS' },
          ],
        },
        {
          label: '单选',
          type: 'radio',
          id: 'radio',
          placeholder: '请选择',
          radio: [
            { key: 1, value: '安卓' },
            { key: 2, value: 'IOS' },
          ],
        },
        {
          label: '文本框',
          type: 'textArea',
          id: 'textArea',
          placeholder: '请输入',
        },
      ],

表单组件

<template>
  <div>
    <a-form-model :model="form" layout="inline">
      <a-row>
        <a-col :span="4" v-for="(item, index) in formData" :key="index">
          <div v-if="item.type == 'input'">
            <a-form-model-item :label="item.label">
              <a-input v-model="form[item.id]" :placeholder="item.placeholder" />

          </div>
          <div v-if="item.type == 'datePicker'">
            <a-form-model-item :label="item.label">
              <a-date-picker
                v-model="form[item.id]"
                show-time
                format="YYYY-MM-DD"
                value-format="YYYY-MM-DD "
                :placeholder="item.placeholder"
                style="width: 183px"
              />
            </a-form-model-item>
          </div>
          <div v-if="item.type == 'checkbox'">
            <a-form-model-item :label="item.label">
              <a-checkbox-group :placeholder="item.placeholder" v-model="form[item.id]" style="width: 183px">
                <a-checkbox v-for="(item, index) in item.checkbox" :key="item.key + index" :value="item.value">
                  {{ item.value }}
                </a-checkbox>
              </a-checkbox-group>
            </a-form-model-item>
          </div>
          <div v-if="item.type == 'radio'">
            <a-form-model-item :label="item.label">

                </a-radio>
              </a-radio-group>
            </a-form-model-item>
          </div>
          <div v-if="item.type == 'textArea'">
            <a-form-model-item :label="item.label">
              <a-input
                v-model="form[item.id]"
                :placeholder="item.placeholder"
                type="textarea"
                style="width: 100%; height: 100%"
              />
            </a-form-model-item>
          </div>
        </a-col>
        <slot></slot> // 插槽 特殊需求单独写入
        <a-col :span="4">
          <a-form-model-item>
            <a-button @click="submit" type="primary">查询</a-button>
          </a-form-model-item>
        </a-col>
      </a-row>
    </a-form-model>
  </div>
</template>

<script>
export default {
  name: 'AntdadminIndex',
  props: {
  //接收父组件拿到的表单内容 然后遍历
    formData: {
      type: Array,
      default: [],
    },
  },
  data() {
    return {
      form: {},
    }
  },

  mounted() {},

  methods: {
    submit() {
      console.log(this.form)
      this.$emit('updateValue', this.form)
    },
  },
}
</script>

<style lang="scss" scoped>
</style>

思路很简单 就是挨个去判断每个对象的类型 然后根据类型去渲染出对应的form对象
