import { SimpleSchema } from 'meteor/aldeed:simple-schema';
import { AutoForm } from 'meteor/aldeed:autoform';

const schema = new SimpleSchema({
  field1: {
    type: String,
    label: 'Field 1',
  },
  field2: {
    type: String,
    label: 'Field 2',
  },
  hiddenField: {
    type: String,
    label: 'Hidden Field',
    autoValue() {
      const field1Value = this.field('field1').value;
      const field2Value = this.field('field2').value;
      // 根据field1和field2的值计算隐藏字段的值
      return field1Value + field2Value;
    },
  },
});

Template.myForm.helpers({
  myFormSchema() {
    return schema;
