FormStateContext

表单状态上下文。

import { FormStateContext } from '@sinoui/rx-form-state';

往上下文中提供formState：

import React from 'react';
import { useFormState, FormStateContext } from '@sinoui/rx-form-state';
function FormDemo() {
  const formState = useFormState();
  return (
    <FormStateContext.Provider value={formState}>
      <form>...</form>
    </FormStateContext.Provider>
  );
}

从上下文中获取formState：

import React, { useContext } from 'react';
import { FormStateContext } from '@sinoui/rx-form-state';
function ChildComponent() {
  const formState = useContext(FormStateContext);
  // ...
}

也可以使用useFormStateContext从上下文中获取formState：

import { useFormStateContext } from '@sinoui/rx-form-state';
function ChildComponent() {
  const formState = useFormStateContext();
  // ...
}
