# 表单联动

valuelink 中配置的 fieldvalue 发生变化时会触发 update 回调, 可以在 update 回调中做一些关于 value 的联动处理

# 类型

type update = (value: any, formItem: formItem, fApi: fApi) => void
1

# 示例

提交
<template>
  <div>
    <v-form-create :formConfig="formConfig" :formData="formData" v-model="fApi" />
    <a-button @click="submit">提交</a-button>
  </div>
</template>
<script>
export default {
  name: 'Demo',
  data() {
    return {
      fApi: {},
      formData: {},
      formConfig: {
        formItems: [
          {
            type: 'input',
            label: 'input1',
            field: 'input1',
            span: 24,
            props: {
              type: 'text'
            }
          },
          {
            type: 'input',
            label: 'input2',
            field: 'input2',
            link: ['input1'],
            span: 24,
            props: {},
            update(value, formItem, fApi) {
              console.log('-> fApi', fApi)
              formItem.label = fApi.getValue('input1')
            }
          }
        ],
        config: {
          layout: 'horizontal',
          labelLayout: 'flex',
          labelWidth: 100,
          labelCol: {},
          wrapperCol: {}
        }
      }
    }
  },
  methods: {
    async submit() {
      const data = await this.fApi.submit()
      console.log(data)
    }
